sender check: a Sender: line is held to the rule From: is held to
test / test (push) Canceled after 0s
The owner's decision (2026-10-16) on the security review's F1: a Sender: line - the sending agent's, shown beside From: as "on behalf of", and signed since 2.8.0 - was neither held to the login nor, before, signed: an application could write its own From: and Sender: ceo@bank.com under this server's signature. Now, when a message has one, it must be one address the application may send as, and at most one such line (RFC 5322 § 3.6); From: is judged first. The refusal is "550 5.7.1 Sender: <address> - <why>", a send-log row of reason "sender" (store.ReasonSender), tagged "wrong Sender"; the message page names the line. The log tailer recovers such a row from cleanup's line as it does a From: refusal (fromRefusalRe reads either). Help text as in the design commit d9d9af3; guide, architecture, security and CHANGELOG say it, security.md keeps Resent-From: (signed, not judged) as an accepted risk. Tests: TestSenderLineHeldToTheSameRule (own address, a name, another application's, a stranger's, two addresses, two lines, From: first), the recovery of a Sender: refusal line, the tag, the message page; e2e sender_check_holds_the_sender_line (own Sender: passes and is signed, another domain's refused at DATA and logged).

panel-dkim-signing stage 2: OpenDKIM removed
test / test (push) Canceled after 0s
The panel's signer is the only one. Gone: the opendkim package and its
configuration, the syslog-relay and opendkim programs, /dev/log and
/run/opendkim, the reload by USR1 through supervisord
(internal/supervisor/supervisor.go), internal/syslogrelay, the port of
OpenDKIM's From: parser (internal/milter/mailparse.go and its probe,
harness and test/upstream scripts), OPENDKIM_SOCKET and OPENDKIM_DIR.
Keys: internal/domain/keys.go (Keys, NewKeys, DKIM_DIR=/data/dkim) keeps
the keys and writes a selector table, /data/dkim/selectors ("<name>
<selector>"), which the signer reads in place of the KeyTable - it reads
no database, as the sender check reads none. The table is written before
the signer serves (EnsureServerSigned moved there from the notifier).
Keys and table 0600, directories 0700, the panel's. The entrypoint copies
/data/opendkim/keys once, as the panel user, into /data/dkim.new renamed
when whole, and stops the start if the copy fails; /data/opendkim is left
for a rollback to 2.7.x.
Sender check: one RFC 5322 address as a mail program reads it, held
against the bindings; the 256-byte refusal and the texts naming OpenDKIM
go. Allowed() folded the domain through strings.ToLower, which makes the
Kelvin sign a "k" - the comparison with OpenDKIM's reading had hidden it;
it folds ASCII only now.
Health: two dkim-signer rows (applications, notifications) in Milter
sockets, opendkim out of the liveness set; the card no longer takes any
row with a note for the spam filter. Texts as in the design commit.
KILL stays in deploy/docker-compose.yml: measured on the test server,
root without it cannot signal a process of another uid - supervisord
stopping the panel, Postfix's master its children. The plan's "only use
was the reload" was wrong; the comment now gives the real uses.
e2e: one signature, the panel's, verified by dkimpy; the /data/dkim modes;
the OpenDKIM log and process checks, testNeverSignedForAnother and the
cited opendkim, libopendkim11 and libmilter1.0.1 go.

base-trixie: the image on Debian trixie, Postfix 3.10.13; Received: hidden on 465/587
test / test (push) Canceled after 0s
The runtime base is debian:trixie-slim, the build stage golang:1.26-trixie:
Postfix 3.10.13 with upstream's 2026 security fixes up to the August
batch, libmilter 8.18.1, OpenSSL 3.5. Every citation of another program in
code, scripts and documents was re-read against the trixie sources
(dev/upstream; bookworm's kept in dev/upstream-bookworm) and updated;
development.md's cited-package table holds the trixie versions.
What the re-reading changed in behaviour:
- logtail: reject lines with sasl_method/sasl_username/sasl_sender
(smtpd_check.c:1019-1026); cleanup's "removed (canceled)" forgets a
port-25 id (cleanup_api.c:363-364).
- internal/postfix/retry.go reads postconf's stdout only: since 3.9 a
deprecated-parameter warning on stderr made one value too many and the
panel fell back to the compiled-in retry policy.
- logrotate-loop.sh: logrotate 3.22 exits 1 when it ignores a config;
the loop refuses on that output whatever the status.
- postfix-config.sh: cyrus_sasl_config_path set explicitly (bookworm's
07_sasl_config.diff is gone); maillog_file_permissions=0640; mynetworks
explicit; Dockerfile: SYNC_CHROOT= in /etc/default/postfix,
opendkim-tools dropped, openssl named, systemd-standalone-sysusers so
cron does not bring the whole of systemd.
- The selfpost group is 10998, outside the system range 100-999: in
trixie a package took 998 and the build failed (owner's decision:
a conflict-free id, the distribution's own ids untouched). The
entrypoint hands /data back by name when the user or the group differs.

audit 6: documents, comments, dead code and staticcheck; the test gaps closed
test / test (push) Canceled after 0s
The last stage of the 2026-10-12 audit; no cut. Doc drift: architecture.md (the sender check in § OpenDKIM, the limit: row's 48 hours, the inbound log and filter-list routes and who may open them, migrations to 0011 and every table, KitPage as production data, Reload configuration as a restore writes, the panel's roles counted), schema-migrations.md (tables and columns since v2), guide.md (a delivery's lines go at the next prune; INBOUND_JOURNAL_MILTER_SOCKET moved to architecture.md's internal list), development.md (the env guard, the deferral the e2e proves, its fixed sleeps), roadmap.md. Comments say what the code does now; TestBaselineIsTheOnlyMigration is TestChainStartsAtTheBaseline; the milter package doc names its three milters. Dead code gone: view.Facts, dmarc HostedSuggestion and ValidateHostedAddress, app UpdateMode (each with the test that alone kept it), the method checks the method-bound routes made dead; Settings.WithResult calls resultFlash. staticcheck 2026.1 in test.yml on both modules, clean: the e2e package builds without its tests now (a test and two constants moved out of non-test files), three findings fixed. The test moved, TestImageBuildPreservesLogrotateMode, had sat in a non-test file and never run; run, it failed on the entrypoint (docker run without a hostname) and now asks with --entrypoint stat. The test gaps no step named, each closed: follow() with mail.log gone past blindMin and made again; CheckRestore with a manifest that is not JSON; the origin check with a port; every /server/ pattern in web.go through server() and in the routes table (it found GET /server/health/fragment missing from the table - guarded, not tested); L9 as the owner decided it on 2026-10-12, the comment on senderSession.Headers and the test passing an h that holds the earlier messages' From:. Plan stage 6 ticked; roadmap audit row done, 81/81. Tested on the test server: go vet + go test of 27 packages, make e2e (all pass, 513 s) on this tree; staticcheck locally on both modules.

audit 4: findings of the two reviews
test / test (push) Canceled after 0s
- Two inbound domains on one upstream could never change its TLS mode,
each save refused for the other (medium): SetTransportAs changes the
mode for every domain on the upstream when the one saving may change
them all; a domain user who may not is refused with the mode, not the
other tenant's domain name (security F1: the first version named it).
- A deletion's leftover DKIM key is removed by Resync (Reload
configuration, a restore's first start) for names no domain has.
- The backup's write deadline moves before Check.
- hasUnsavedEdit skips password and file fields and compares a multiple
select's options; htmx.config.timeout 30 s, so a refresh never answered
ends and is tried again; a failed refresh's promise is handled.
- An empty filtered Outbound log says no message matches the filters.
- The dummy bcrypt hash is made at start; a DMARC part over 8 MiB is
refused for its size like the other two limits.
- Health's Configuration box says what Reload writes (design first,

audit 4: DNS outages unknown, DMARC limits said, typed Health, one TLS mode per upstream
test / test (push) Canceled after 0s
M14, M15: queryEach gives each resolver 2 s within the check's context and asks the one that answered last first; an address or PTR lookup not answered is Unknown, an answered mismatch beside it still an error; Checker.Server keeps the last answer's addresses, so SPF does not go Unknown with it. Notifications report faults only, now tested with SPF unknown alone and beside a wrong DKIM. DMARC reports: tests of malformed XML, gzip and zip bombs, a message over the limit, the service's Resync, hosted suggestion and validation. The finding: both limits cut silently and an oversized report failed as damaged; readAtMost refuses it for its size (MaxMessage 10 MiB, moved into IngestMessage). healthReadings replaces map[string]any for Health and Overview. L5: an inbound upstream has one TLS mode - a second domain to the same [host]:port with another mode is refused, naming the first; the TLS policy map holds each next hop once. Tested on the test server: go vet + go test of 25 packages, make e2e (all pass, 631 s) on this tree. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

test / test (push) Canceled after 0s
Step 4 of stage 4 (L10, L11, L13, L18, L19 and a row of
review-2026-08-followups):
- The Outbound log counts first and clamps the page to the last; a number
too large for an int (strconv's ErrRange with the largest int) is the
last page on both logs. Tested at the edges: first, last, past the last

audit 4: sign-in timing and sessions, server timeouts, polling that recovers
test / test (push) Canceled after 0s
Steps 1-3 of stage 4, tested together (their docs share files).
Step 1 (M8, L15, L16): an unknown name pays a bcrypt comparison at the
panel's work factor too (noSuchUserHash, made once) -
TestLoginTakesAsLongForAnUnknownName holds the medians within a factor of
two; the Account form's current-password check has its own limiter, per
user (AllowPasswordChange); a sign-in destroys every session the request
presents before it issues its own.
Step 2 (L14): newHTTPServer - ReadTimeout 30 s, WriteTimeout 60 s,
IdleTimeout 2 min beside ReadHeaderTimeout; the full backup moves its write
deadline to two hours through http.ResponseController (e2e: the log shows
no failure to move it).
Step 3 (M11), read in htmx 2.0.4's source (dev/upstream/htmx-2.0.4, the npm
build byte-equal to the shipped htmx.min.js): the poll passes source: box,
and the next refresh is scheduled from htmx:afterRequest, which htmx fires
on load, error, abort and timeout, and after a swap on the nearest parent
left (the box found by detail.target's id); failures in a row double the
wait to 60 s. RequireAuth answers htmx with 401 + HX-Redirect: /login,
which htmx follows before it looks at the status. testdata/poll_test.js
runs panel.js in node against a stand-in DOM and clock (TestPanelJS; skipped
without node, which the test server lacks - run here, and it fails on the
old panel.js).
Also measured: the stage-3 e2e regression for H1 fails as it should on HEAD
with the old entrypoint ("check data/postfix/e2e_extra_map: permission
denied", the panel restarting).
Tested on the test server: go vet + go test of 25 packages, make e2e (all
pass, 639 s) on this tree.

audit 3: backup CLI, envelope budget, directory sync, docs; findings of the reviews
Steps 3-6 of stage 3 and what the two reviews found in steps 1-6, in one commit: the review fixes sit in the same hunks. Step 3, CLI backup (M3, M5, L1, L2; L4 of the stage's list): - backup.snapshotDB refuses a database that is not there and opens the source mode=ro (measured: mode=ro creates no file). - selfpost-backup holds an encrypting password to validate.MinSecretFilePasswordLen; -o of both directions writes a temporary file beside the name and renames it whole; -decrypt peeks the first chunk (password and type authenticated) before the output exists. - what a backup leaves out (a link under data/, a link under certs/ to a directory, a socket...) is told to OnWarn; certs/ with no file is backup.ErrNoCerts, refused by Check and Create, named by the panel. - parseTrustedProxies: a bare address takes /128 when written with a colon (::ffff:10.0.0.1/32 was ::/32). Step 4, secretfile (M4, L3): scrypt's V at most 128 MiB, r <= 64, p <= 2; bytes after the last chunk are ErrCorrupt. Step 5 (L7): atomicfile.SyncDir after the rename, used by Write, replaceSASLDB and the CLI; atomicfile_test.go. Step 6: security.md and guide on backup and restore. Reviews (technical, security): - H1: a restore of a server with DMARC on was refused on every start - the archive records no owner, tar as root left the DMARC maps root's, and the entrypoint only chowned the maps it named. It now hands every file beside queue/ in /data/postfix to panel:selfpost 0640; e2e writes an extra map before the backup and finds it panel:selfpost 640 after a root unpack. - the comparison reads regular files only (Lstat, size, LimitReader); a record unpacked again wins over the earlier check's mark; ConsumeRestore removes both; the mark is synced; a journal file beside a freshly unpacked database is refused. - AttachRefusalLine refuses an empty line as the old statement did; skipped entries named in words; -decrypt of an empty payload is no failure; guide wording on the shell's '>' and a killed CLI; the in-place restore's 'mv .' (older than this stage) fixed. Tested on the test server: go vet + go test of 25 packages, make e2e (all pass, 643 s) on this tree. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

audit 3: a restore is ended by its Resync, and half an archive is refused
test / test (push) Canceled after 0s
The restore manifest was consumed as soon as its version was checked, before store.Open and the Resync; a start that failed in between left a data directory the next start took for an ordinary one (M1). openData now runs CheckRestore, store.Open, the Resync, and only then ConsumeRestore. A truncated archive had nothing to refuse it: the manifest is the first entry, so a download cut short or a tar stopped by a damaged block was a restore on half a database. Every archive now ends with data/contents.json, the size and SHA-256 of each data/ file (deploy files are the operator's to edit), and CheckRestore compares /data with it before the database is opened, then renames it contents.checked.json so a start after a failed one does not compare again unless the manifest changed. Tests: a start whose Resync fails, then a start that resyncs and consumes; an archive cut in the database, before the deploy files and in its last entry (refused, database untouched, no -wal); a damaged key named; the record's names confined to data/; the domain import of a cut plain export, a cut and an altered .spde (refused, nothing created). e2e on the test server: full_backup_restore now also sees contents.json in the archive and gone after the first start, through the real entrypoint and daemons (all pass, 762 s); go vet + go test of 24 packages pass there.

audit 2c: findings of the two reviews
test / test (push) Canceled after 0s
Technical review (Opus, 11 findings, 2 medium) and security review (Fable, no high or medium) of 3c86280..HEAD. Both confirm the port gives dkim_mail_parse()'s result on every input it parses, and that no line the check passes is signed with another domain's key. - F1 (medium): OpenDKIM's parser takes lines no mail program reads as one address - "ceo@bank.com:me@mine.com", "Name <ceo@bank.com:me@mine.com>", "<b@evil.com, a@mine.com>", "ceo@bank.com <me@mine.com>", "ceo@bank.com@mine.com" - and signs for the last while a lenient reader shows the first. The line must now also be one address in RFC 5322's grammar (net/mail, display names in any charset passed through), at the domain OpenDKIM signs for. A quoted display name may still hold anything. - F2 (medium): the bindings were asked about OpenDKIM's form of the address, quotes and all, so "x"@mine.com passed for an application holding @mine.com while x@mine.com belonged to another. They are now asked about the reader's address, its local part unquoted, as Postfix holds the envelope's. - F3 / security (low): Bindings.Allowed and DomainOf fold case in ASCII only: Postfix folds as Unicode (casefold.c, ICU), but every key and login the panel writes is ASCII, and the Unicode fold let the Kelvin sign pass for "k" (net/mail then refuses such a line on the domain test). - F4 (low): a TERM between "postfix start-fg &" and "child=$!" is no longer lost: the wrapper stops Postfix as soon as the pid is known. - F5 (low): for startsecs after a start any failed reload passed as "not running". postfix-reload is now build/postfix-reload.sh: exit 75 when master -t says no master runs, else exec postfix reload; RunOnce returns EndError with the status, and only 75 is taken as done. supervisor.State goes. - F6 (low): crashexit spares postfix-reload too - a reload that could not be spawned is reported to whoever asked, not a reason to stop the container. - F7 (low): a certs/ that is itself a link is resolved before the walk (filepath.WalkDir does not follow its root). - F8 (low): at shutdown the tailer reads what is left of the rotated file before saving its place. Not changed: a refusal line still waiting on the old file at shutdown is not kept - the panel writes refused rows itself, only a kill loses one, and that window is the minute's grace. - F9 (low): pct read as text - empty or unreadable is 100, the rest held to 0..100. - F10 (low): the directory is synced after sasldb2's rename. - F11 (low): POSTFIX_STARTSECS by expr, so "010" or "08" in MILTER_WAIT_TIMEOUT are decimal, not octal or an error. - Security (low): pagehide also empties defaultValue - the input's value attribute and the textarea's text - not only .value. A sasldb2.new left by a killed panel is removed at start (entrypoint) and never archived. security.md says that links under certs/ are followed and by whom they can be placed. Tests: sender check cases for F1 (four lines), F2 (a bound address quoted, for its owner and for another), F3; EndError's state and status; pct cases. architecture.md and CHANGELOG describe the reader rule. Stand (2026-10-15, make e2e, exit 0); go vet and go test ./... pass on the server (24 packages). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

sender check: From: read with OpenDKIM's own parser; L8 closed
test / test (push) Canceled after 0s
Audit 2026-10-12, stage 2c, the owner's decision of 2026-10-14: the check
decides by the address OpenDKIM signs for, whatever a display name or a
comment holds.
internal/milter/mailparse.go ports libopendkim's dkim_mail_parse() with
dkim_mail_first_special(), dkim_mail_token() and
dkim_mail_matching_paren() from Debian's opendkim 2.11.0~beta2-8+deb12u1,
line for line: the '<' form, group and list punctuation, an '@' before the
first ':', ';' or ',' deciding where the address starts, source routes
dropped, quoted strings and domain literals kept with their delimiters,
comments skipped, whitespace between atoms one space, no encoded word
decoded; and the C's own quirks ("@d" gives d as the local part too).
testdata/mailparse_harness.c compiles the C from the image's source; the
test feeds it and the port 200 019 lines (the hand-written cases and
200 000 random ones over the specials) - 93 443 parse and agree byte for
byte, 106 576 fail and agree on the error (on an error the C leaves its
in-place result unterminated, and OpenDKIM uses neither part then).
judge(): one From: field and one address stay required (moreAfter: only
list or group punctuation may follow); what OpenDKIM cannot read is
refused (mlfi_eoh() would not sign it); the address is lower-cased in
ASCII only, as dkimf_lowercase() and Postfix's tables do. Found reading
dkimf_apply_signtable(): OpenDKIM matches its refile SigningTable against
"user@domain" printed into MAXADDRESS + 1 = 257 bytes, so a longer address
is matched cut short - a quoted local part padded to end there in
"@another.tenant" would be signed with that tenant's key while its real
domain is the application's. Such an address (over 256 bytes) is refused;
one that fits is matched whole. The display-name and comment scan, the
"one @ outside quotes" rule and the SigningTable reader (Signers) go; the
check asks for header values with their leading space as OpenDKIM does
(OptHeaderLeadingSpace; Postfix keeps a v2 milter's event mask, milter8.c
milter8_negotiate()).
L8 closed: refused or passed no longer depends on other domains of the
server; security.md's accepted risk is struck. The shared other-sender
lines are now held to "never signed for the other sender": unit test (a
passed line is read at the application's domain) and e2e (a passed line
arrives signed for the application's domain, none for the other).

audit 2c: what only the stand could answer, measured and written down
test / test (push) Canceled after 0s
All 2026-10-15; each written beside the code or text it settles. - A-43: /usr/sbin/postlog is -rwxr-xr-x root:root in the image (postfix 3.7.11-0+deb12u1; dpkg-statoverride lists postdrop and postqueue only): Debian does not install it set-gid, so it is no use to dmarc-ingest (cmd/panel/dmarc_ingest.go). - C-X1: OpenSSL 3.0.22 in the image prints the same public key from `x509 -pubkey` and `pkey -pubout` for RSA-2048, P-256, P-384 and a SEC1 P-256 key - cert-reload's same_pair holds for certbot's ECDSA keys. - C-K5, D-guide:933/:233: on the live server (Docker 29.6.1, userland proxy on 0.0.0.0 and ::, no IPv6 on the network) an outside IPv4 client and the host's own public IPv4 address are logged as themselves; the host's IPv6 address and 127.0.0.1 arrive as 172.18.0.1. Over IPv6 every client is the gateway: one level-1 budget, an application IP list cannot name them, rspamd sees the gateway. Guide paragraph under level 1, notes at the milter and allow-list, comments at the anvil setup and authip.go, and a Security entry in the CHANGELOG (an allow-list naming the gateway would admit every IPv6 client). - D-guide:61: a published port nothing listens on (a throwaway container, -p 20999:25) is refused from outside over IPv4 and from the host's public IPv4, accepted and closed through 127.0.0.1 - Docker's proxy, which IPv6 goes through too (not probed over IPv6 for this). - C-M8: the live installation has received one DMARC report, of one record: nothing to set maxReportRecords by yet - said at the constant. - D-S7, D-arch:516, D-arch:532: a new database filled through the store to 120 days at 1 900 messages a day (228 000 messages, 1.37 million lines, 464 MB) on the test server (2 cores): the longest write is the line prune after a 30-day gap, 1.9 s for 342 000 lines (0.4 s with nothing to delete); the send-log delete 0.6 s; 2 000 lines of a tailer pass 18 ms; VACUUM INTO 1.7 s; a second connection writing every 50 ms waited 1.8 s at most, no SQLITE_BUSY - inside busy_timeout's 5 s. architecture.md's "about a second per million lines" was five times too fast; its "six to ten lines of 200 bytes" is 6.0 lines of 146 bytes on the live data. - D-B16: which favicon is fetched, by the probe server's log: Edge 155 the SVG, the desktop app's embedded Chromium 152 the PNG, with or without sizes="any" - layout.html's "vector wins where supported, raster catches the rest" holds; Firefox and Safari not measured. - D-arch:121: the allow/deny trial again, in rspamd/rspamd:3.11.1-3 with today's multimap.conf: every mix of allow and deny entries matching one message ended reject; a changed map was used about 10 s later. - D-sec:424: rspamd runs as _rspamd, uid 11333; the panel is uid 999.

D-B3. Fetch Standard § 3.2 "append a request `Origin` header": under Referrer-Policy no-referrer a request that is not GET/HEAD and not CORS - a form POST, a navigation - gets Origin "null". originAllowed() refuses "null" whenever Sec-Fetch-Site is absent, and Fetch Metadata § 3 sends Sec-Fetch-Site only to a potentially trustworthy URL: every form, sign-in included, failed in Safari before 16.4 and in any browser on a plain-HTTP panel at a name. same-origin nulls Origin only for a request not same origin with its URL and still sends no referrer to another site. The comments of the origin check say so. D-B13. noStore keeps the page out of HTTP caches (RFC 9111 § 5.2.2.5); a history mechanism "might honor" it (§ 6), and Pragma in a response "was never specified" (§ 5.4) - it goes. CopyField.Secret marks the password of out-app-created data-secret, and panel.js empties such fields on pagehide (HTML § 7.5.9, "unload a Document", step 10.2: fired whether or not the document is kept for history traversal). Measured 2026-10-15 in Chrome 152 (the desktop app's browser), a local probe page with Cache-Control: no-store and a data-secret field: Back reloads it (pageshow persisted=false, a new load), so this browser keeps no-store pages out of its back/forward cache; the handler, fired on the same page, empties the field. Firefox and Safari not measured. Tests: the header value; the created page has the password data-secret and the login not, no Pragma. Stand (2026-10-15, make e2e, exit 0): new form_post_with_the_browsers_origin - Referrer-Policy: same-origin on a page; a POST carrying the page's own Origin and no Sec-Fetch-Site, what a browser sends now, passes; one carrying Origin: null, what it sent before, is 403. (A first run failed where the e2e client and a view test scraped the old input markup; both read data-secret now.) go vet and go test ./... pass on the server (24 packages).

health: sockets dialled, the certificate Postfix serves, "deferred" only for the queue
test / test (push) Canceled after 0s
Audit 2026-10-12, stage 2c, "Health says what is served"; the pages of
ea8b6bf's mockup.
Sockets (A-38). A unix socket's file outlives a killed OpenDKIM or panel
and refuses every connect() (unix(7)); Health said "Listening" from a
stat. CheckSocket and CheckMilter's unix case now dial: refused is
"Nothing listens on the ... socket: the program that made it has
stopped", EACCES is unknown (the panel may not connect), anything else
"does not answer". The probe closes before a byte, which no milter logs:
libmilter takes the EOF as SMFIC_EOF without a line (sendmail
8.17.1.9-2+deb12u2, the image's libmilter1.0.1, libmilter/comm.c
mi_rd_cmd(), engine.c mi_engine() - its source is now in dev/upstream),
OpenDKIM's mlfi_close() has no connection to free, go-milter v0.4.1
returns quietly on io.EOF (session.go, HandleMilterCommands()). The page
polls every 5 s while in view, so this mattered.
Certificate (A-65). Postfix serves build/postfix-config.sh's copy,
refreshed by cert-reload every TLS_RELOAD_INTERVAL_SECONDS. The panel now
reads smtpd_tls_cert_file from postconf -h at its start (as the retry
policy) and TLS_RELOAD_INTERVAL_SECONDS; CheckServedCertificate checks the
served copy and, when the mounted file differs byte for byte (cert-reload's
own cmp -s), names it as Renewal: its expiry and mtime, two facts on the
card. Waiting is fine for the interval: a nearing expiry of the served one
is then no warning (an expiry still an error); past interval + 1 h it is a
warning pointing at cert-reload's lines. The notifier sends no expiry
notice while a renewal waits on time.
Wording (D-P1, D-P3, and the same for the spam filter): Sender check
note, help topics sender-check, upstream, filter, certificate - word for
word as in the mockup; the filter row's detail too.
Tests: stale socket file (Linux) refused for CheckSocket and CheckMilter;
CheckServedCertificate (same, waiting, late, expired + waiting, no served
path); intervalText; the card's facts; the notifier quiet while a renewal
waits, speaking once it is late. Stand (2026-10-15, make e2e, exit 0):
new health_shows_what_is_served - the three sockets dialled ok by the
panel's user; a certificate mounted without its key is refused by
cert-reload ("do not belong together") and the card shows the served
expiry, "Renewal expires" with the mounted one's, "Renewal mounted", and
"Postfix still serves the certificate above."; a matching pair is then
served again. go vet and go test ./... pass on the server (24 packages).

log tailer: the rotated mail.log read until postlogd lets it go
test / test (push) Canceled after 0s
postlogd opens maillog_file once per process (Postfix 3.7.11,
src/postlogd/postlogd.c, pre_jail_init()) and leaves it only when it
exits: at "postfix reload" master closes the service's status pipe
(src/master/master_service.c, master_restart_service() ->
master_status_cleanup()) and dgram_server_abort() exits on reading its end
(src/master/dgram_server.c). logrotate renames and creates, then runs the
reload (build/logrotate-mail.conf postrotate; logrotate 3.21.0,
logrotate.c, rotateLogSet(), after rotateSingleLog()), so lines go to the
renamed file in between, and the tailer, already on the new one, never
read them (assumptions A-33). follow() now keeps the renamed file open as a
rotatedTail and reads it on each tick for rotatedGrace (a minute, far
longer than the gap); its places are never saved as the resume point, so a
restart still reads the rotated file through readRotated. A truncated file
is not kept.
The RFC 3339 stamp goes (A-12): it was written for a maillog_file_format
said to arrive in Postfix 3.9; there is none in 3.7.11 nor in the 3.12
snapshot of 2026-09-25 (proto/postconf.proto; msg_logger.c,
msg_logger_print() keeps strftime("%b %d %H:%M:%S ")). Every fixture now
carries the stamp Postfix writes; logtail's TestMain fixes time.Local to
UTC, since the stamp is local time and this PC is UTC+3.
Tests: TestFollowReadsTheRotatedFileAfterTheSwitch (Linux: a line appended
to the renamed file after the switch reaches the store). Stand
(2026-10-14): go vet and go test ./... pass on the server (23 packages);
make e2e exit 0, delivery_log_survives_rotation included. The tested tree
was this commit plus the previous one; the CHANGELOG entry was written
after the run, and a comment's logrotate citation corrected
(rotateLogSet runs postrotate, not rotateSingleLog).

log tailer: expiry, Postfix's time values and refusal lines as Postfix writes them
test / test (push) Canceled after 0s
Expiry (assumptions A-8). Postfix 3.7.11 logs the end of a message's queue lifetime once per message, "<id>: from=<..>, status=expired, returned to sender" (src/qmgr/qmgr_active.c, qmgr_active_done_25_generic()), with no line per recipient; the tailer waited for "to=..., status=expired", which no Postfix writes, and the sweep closed only queued rows, so such rows stayed deferred. The tailer now reads qmgr's line (ExpireMessage: each recipient's newest open row of the id becomes bounced); the sweep closes a deferred row too when Postfix no longer holds the message, and counts as missed only a final line (sent, bounced, expiry). The queue listing's '#' (forced expiry, showq_compat.c showq_message()) is read as a flag (B-PQ1). Time values (B-PQ10, B-PQ11): conv_time() ported - one number, one lower-case unit, the parameter's default unit when none (get_def_time_unit: d for the lifetimes, h for delay_warning_time), the rest ignored; postconf -h -x expands $name; bounce_queue_lifetime capped at maximal_queue_lifetime as qmgr_post_init() caps it, so LongestLifetime is the queue lifetime. Refusals (A-21, A-23, A-24, A-15): smtpd_whatsup() ends the NOQUEUE line with sasl_username=<login> on an authenticated session; the line is now matched to its row by client, login and sender, and a line without a login is no application's. The client= line's login ends at the comma. The "IPv6:" trim goes (namaddr is built from state->addr). A row recovered from cleanup's line says that line names the last recipient only. Stand (2026-10-14, make e2e, exit 0): new expired_message_is_closed - defer_transports=smtp makes the retry service defer the message, postsuper -e and postqueue -i force its expiry; mail.log has "<id>: from=<alerts@sender.e2e.test>, status=force-expired, returned to sender" and the row goes deferred -> bounced; refusals_show_postfixs_line passes with the login match. go vet and go test ./... pass on the server.

findings of the reviews of audit stage 2b
Technical review (Opus) and security review (Fable) of 5be109b..5154bba;
reports in the session's scratchpad. Nothing above low from security; one
bug and three risks from the technical review. Migration 0009 is not
deployed, so it was extended.
- Bug: two refusals of one second swapped their NOQUEUE lines (each line
went to the newest lineless row). AttachRefusalLine now matches the
client address too (send_log.client_ip, written by the journal milter -
Postfix's line names the client and the sender, never the login: the
sasl_username part of the pattern never matched and could be fed by HELO,
security F1/F2), takes the nearest row in time and the oldest of equals,
and a line already on a row goes on no other (security F6).
- Waiting lines and recoveries lived only in memory while the saved offset
moved past them: a stop within 30 s lost them. The tracker now never saves
an offset past the oldest waiting item in its file (tracker.hold,
refusalLines.oldest) - for a recovery, the client= line that names its
login - so they are read again; the "once" guards make that harmless.
- A recovered row whose login the tailer did not see was nobody's: its
domain_id falls back to the envelope domain's.
- The fingerprint's file identity is the inode alone: the device number can
change across a host reboot and make the same log look rotated.
- A refused row carries its queue id; UpdateStatus's "newest row" now skips
refused rows, so a later message with that id does not flip it to sent.
- The alive mark: its age is read first and kept from then on, so asking
supervisord for 30 s cannot make it stale; the entrypoint removes it with
the sockets - a container restart is not the check's downtime, and a mark
from before would have counted the whole outage as "≈".
- Security F3: the sender check prints no ";" of the client's in the From:
text of its reply, and the tailer reads the envelope after the first ";"
- Postfix's own text.
- A refused row with a queue id and no stored lines says so (it was told the
mail.log text of 2.2.0); the fact's em dash is the house hyphen.
- Docs: architecture (client address, no login), guide § Health (warns on
either count), help topics log and sender-check (design

message page: a row the sweep closed says the panel closed it (stage 2b)
The History step of every bounced row said the receiving server refused
the message permanently or Postfix gave up, "the reason is in the delivery
log below" - for a row the reconcile sweep closed (reason "reconcile")
neither is known and the log has nothing (review of stage 1). Such a row's
step is now "Closed by the panel - Postfix no longer held the message and
mail.log never said what became of it ... rather than show a delivery it
cannot evidence." The help topic log names the case (design

logtail: a refusal the panel did not get to write is written from mail.log (stage 2b)
test / test (push) Canceled after 0s
The sender check answers 550 5.7.1 and writes the refused row through a
buffer a moment later; a panel stopped in between (a rollout, a kill) left
an application refused and a log that did not know it. A refusal at MAIL
FROM needs nothing: the journal milter writes its row before it answers.
- logtail.refusalLines remembers each queue id's login from smtpd's
"<id>: client=..., sasl_username=<login>" (4096 ids at most) and, on
cleanup's "<id>: milter-reject: END-OF-MESSAGE ...: 5.7.1 From: <line> -
<why>; from=<...> to=<...>", waits 30 s and hands it to
store.RecoverRefusal - an INSERT ... WHERE NOT EXISTS a refused row of that
queue id within two minutes: the row the panel wrote, or one recovered
before, means nothing is written. It is read from the saved offset on, so
a kill is covered as well as a clean stop - which a flush of the buffer at
shutdown would not.
- Migration 0009 (not deployed yet) gains send_log.recovered; the row is
written with the line's time, the login's domain id, reason "from", the
From: line as the check printed it (to the last " - " before ";").
- The message page: a fact "Written: from mail.log after a restart: the
panel stopped before it wrote the refusal".
Tests: store (not written when the panel wrote it; written once however
often); logtail (the login from client=, the From: line with a " - " in it,
nothing before the wait is over); view (the fact). e2e
refusal_recovered_from_the_log: a From: refusal, the panel stopped, its row
deleted and the tailer's saved place moved before the message's first line
(python3 in the container, as the panel's user - a kill cannot be timed to
that moment from outside); started again, the row is back, recovered, once.
Also fixed: handlers TestMessagePageOfARefusedMessage still expected the
old sentence; it failed on the server after

refused messages: the page shows what Postfix wrote (stage 2b, 0009)
The Delivery log box of every refused row said "This message never reached
the queue, so Postfix wrote no delivery lines for it" - untrue: Postfix
wrote a line for each. The owner, 2026-10-13: the box is required on every
message page. Pictured for him first (dev/shots, the refused variant of
out-message: wrong From with its queue id lines, rate-limited with the
NOQUEUE line); the variant has no mockup screen of its own - the guard ties
screens to pages, and its outline is out-message's.
- Wrong From: cleanup gives the message a queue id before the headers are
judged; the sender check reads {i} at end-of-headers and writes it on the
refused row. Its lines - stored under the id like any other's - are on the
page, but only those from 10 minutes before to 1 minute after the refusal
(store.SendLogLines for a rejected row): Postfix frees the id at once, and
a later message with it lends nothing. No mail.log fallback for a refused
row, for the same reason.
- Rate-limited and wrong client: refused at MAIL FROM, no queue id. Migration
0009 adds send_log.refusal_line; logtail.refusalLines matches smtpd's
"NOQUEUE: milter-reject: MAIL from ...; from=<...>" (not port 25's, not
CONNECT/EHLO) and store.AttachRefusalLine puts it on the newest refused row
of that sender (and login, when the line names it) within two minutes; a
line whose row is not written yet waits up to 30 s (retried at each pass).
- The page: the queue id fact says "given, the message was not queued" or
"none - refused at MAIL FROM, before one is given"; the box's caption is
"The line from mail.log for this refusal" for the latter; a row from
before says the line was not kept. LogLineLevel colours a refusal by its
reply: 5xx red, 4xx amber (IPv6 clients included). The id in the fact is
not muted as in the picture: the kit has no muted inline.
Tests: store (attach by sender, login, time; not a queued row, not one an
hour off; a refused row's lines are its own minutes); logtail (attach, wait
and retry, port 25 and other lines ignored); milter (the refused row carries
{i}); view (facts, caption, line levels); handlers (the line on the page,
the sentence without it). e2e refusals_show_postfixs_line: a client-address
refusal made there, and the pages of a wrong From, a rate-limited and a
wrong client refusal each show Postfix's line.
schema-migrations row 9, CHANGELOG [Unreleased], audit plan line ticked,
roadmap 25/62.
Evidence on the test server for this tree: make e2e exit 0 (the new case
in 5.4 s); go test ./... ok but for two schema tests, fixed after the run
(the schema at 0009) - store tests ok locally; the full run follows before
the push.

findings of the reviews of audit stage 2
test / test (push) Canceled after 0s
Technical review (Opus) and security review (Fable) of a59e3d4..cb5a4a2;
reports in the session's scratchpad. Nothing critical, high or medium; no
outright bug. Fixed:
- F2, F3 (0008 backfill, before it runs on the live database): rows are
filled by the rule new rows follow - the application's domain, then the
name's - and only by a domain and application that existed when the row
was written (created_at); the inbound log likewise. Test: the migration's
UPDATEs re-run on prepared rows (before the domain, after, null sender,
application gone, a stranger's name). Dry run on a copy of the live
database: 68/68 and 10/10 rows filled, none disagreeing with its login's
domain, integrity ok.
- V2, F4: an application's statistics and level-2 count are its login's
rows of its domain (appByLogin), and StatsWindow starts no earlier than
the entity's creation; the message page's "may send as" only for a login
still of the row's domain. Test: a login taken again in another domain
starts at zero.
- F7: MAIL FROM:<> is held to the domain limit of its login
(ApplicationByLogin fills DomainName).
- V3: an imported DKIM selector is held to DNS labels (validate.Selector).
- F5, F6: an imported auto limit's numbers are dropped and recalculated
right after the import; its mode is stored trimmed.
- V6: the store refuses a role that is neither global nor domain.
- F9: SaveUser keeps the stored hash when no new password is given (the
form no longer writes back the hash it read). F10: a reach naming a
domain deleted meanwhile is ErrNoSuchDomain, answered on the form.
- V4, F12: from-lines-other.txt - lines naming another sender ({other}) in
a quoted string, a quoted pair, capitals, a comment, an encoded word, a
quoted local part; the unit test wants each refused, the e2e
(lines_naming_another_sender_never_signed_for_it) wants each refused and
none signed for it. The passed list gained a.{DOMAIN}, a comment after
the angle address, a quoted local part, and "b@ {other}" - passed by
design (security.md), and the e2e shows it signed for the own domain.
- F13: e2e login_in_other_capitals_does_not_authenticate - AUTH with the
login upper-cased gets 535.
Not changed, written down: V1/F1 - L8 is half closed (refused or passed
still tells an application which domains are hosted here); security.md's
accepted risks and the CHANGELOG say so, and the owner is asked whether to
refuse every foreign address in a display name (changes the 2.4.0 rule).
F11 - deleting a domain rewrites its rows' domain_id (seconds at 1e5 rows),
accepted at this size. F8 (test cannot tell write-first from read-first;
the reviewer verified it with two stores, 30/30), V5, V7, P2: noted.
Evidence on the test server for this tree: go vet clean, go test ./... 23
packages ok, make e2e exit 0 with the three new cases.

send log: rows belong to a domain by id (audit L12, 0008)
A domain user's log, the message page, a domain's statistics, the level-2 count and the notifier's refusal count picked send-log rows by domain name, so a domain deleted and re-added under its old name showed its earlier mail to the next assignee and went on counting it. Migration 0008 (not run on the live database yet, so extended here): send_log.domain_id and inbound_spam_log.inbound_domain_id, REFERENCES ... ON DELETE SET NULL, filled once by name from the registry as it is at migration time, each with an (id, created_at) index. - Writes: InsertQueued / InsertRejected set domain_id to the domain of the row's login (loginDomainID) - the journal milter and the sender check's refusal rows both go through them; the inbound journal sets inbound_domain_id from the inbound domain's name at insert. - Reads: SendLogFilter.DomainIDs (was Domains, by name) and InboundSpamFilter.DomainIDs are the scope; the global role still reads everything. The message page checks row.DomainID against the user's domains. DomainSendStats and CountMessages keep their name argument and select domain_id = (SELECT id FROM domains WHERE name = ?). The notifier joins send_log.domain_id to the domain and its application. - DMARC reports stay by name on purpose (a report is about the DNS name). Tests: store - scope by ids; a re-added domain's log, level-2 count and statistics hold its own row only, the global log both; inbound scope by ids. Handlers - the new assignee gets 404 for the old row's page and does not see it in the log, the global role sees both. Tests that wrote rows for a login that is no application now register it (a row is a domain's through its application). Schema at 0008 with the two columns and indexes. schema-migrations row 8, CHANGELOG [Unreleased], audit plan line ticked, roadmap 19/62. Evidence: go vet ./... clean; go test ./... ok locally but for the two Windows-only tests; the server run follows before the push. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

import: the export file held to the forms' rules before anything is created (audit M10)
test / test (push) Canceled after 0s
domain.Import trusted the file for everything but the domain name, the selector and the password: DMARCRua was not validate.Email'ed, client IPs not parsed, a rate limit's mode, window and count not checked - a window of 0 counted nothing, a garbage IP made the application refuse every client. handlers.checkDomainImport runs in HandleImportDomain after the domain name check and before Import, and refuses the file with "Invalid <what> in export file: <the form's own text>": the report address (validate.Email), each rate limit (parseRateLimitMode; auto - checkAutoMultiplier, 0 meaning the default as an empty field does; manual - checkManualLimit, which the form now uses too: count > 0, <= the level-1 backstop, window > 0; both 0 is an export without a limit of its own), each application's client addresses and the legacy ones on its rate limit (parseIPList, written back as the form stores them; allow-list on with none is refused). Login, sending addresses and password stay checked in app.ImportApplication. Tests: a good export passes and its addresses come out normalised; nine broken fields each refused with their message; a refused file posted to the handler creates no domain.

store: users saved in one transaction, the last global kept inside it (audit M7, M9)
M7: DeleteUser counted the global users and then deleted; the handler's demotion and CreateGlobalUser checked and then wrote. MaxOpenConns(1) serialises statements, not pairs: two globals deleting or demoting each other at once could leave none. Now: - DeleteUser: a transaction that deletes first (taking the write lock) and then requires a global left (requireAGlobal) - ErrLastGlobal rolls back. - SaveUser: likewise for a demotion, the count inside the transaction after the write. The handler's early count stays only to answer before hashing a password; SaveUser decides, and ErrLastGlobal maps to the same message. - CreateGlobalUser: INSERT ... SELECT ... WHERE NOT EXISTS (SELECT 1 FROM users), one statement. M9: submitUserUpdate made five writes in a row (UpdateUser, sessions, SetUserRole, ClearUserReach with its error only logged, SetUserReach). store.SaveUser(UserChange) writes name, hash, e-mail, role and reach in one transaction (a global user's reach cleared); sessions end after it commits. The create path had the same flaw - user, reach and then e-mail in three writes - and now goes through AddUser, one transaction; CreateUser stays as a wrapper for its many test callers. SetUserRole is gone; writeUserReach is the reach write inside a transaction. Tests: store - two globals demoting, and deleting, each other from two goroutines: exactly one refused, one global left; a refused SaveUser (taken name, a reach to no domain, nothing assigned) changes nothing; promoted to global loses the reach; AddUser with a bad reach leaves no user; four setups at once create one user. Handlers (the users pages, direct): the whole change saved, back to domain with a reach; the last global not demoted and the typed rename not written; a domain user with nothing assigned refused, nothing changed; create with e-mail and reach.

from-header-binding: the sender check, what it costs, its pages; guide, architecture, security
test / test (push) Canceled after 0s
A message's From: line is held against the application that sends it, under the rule Postfix holds the envelope sender to. OpenDKIM chooses the key by that line, so until now an application could have mail signed as another domain of the server or as the server itself. The check (internal/milter/sender.go) - A role of the panel on a socket of its own (SENDER_CHECK_SOCKET), first in smtpd_milters and strict: default_action=tempfail. The journal milter keeps its socket and stays fail-open. postfix-wrapper waits for the new socket. - It reads no database: what an application may send as comes from Postfix's own sender_login_maps, what the server signs for from OpenDKIM's SigningTable. Both are read again when they change; one that cannot be read defers mail. - One From: field, one address, allowed by the envelope's lookup; then no other name of the SigningTable may appear anywhere in the raw line. Refused: 550 5.7.1 naming the line, reduced to printable ASCII. - A refusal is a send-log row with reason "from" and the header address (migration 0006), written by another goroutine and not waited for. The journal's refusals record their reason too (limit, client), and the notifier takes only a limit's. What it costs (docs/plans/from-header-binding.md, Statistics) - The role marks itself alive every 2 s; at start the gap since the mark is downtime, counted from Postfix's start if later and not at all when supervisord says Postfix is not running. - The log tailer counts the connections Postfix turned away: a warning that names the socket, then milter-reject "Service unavailable" from the same smtpd. Seen on the stand: the client is refused from CONNECT on and leaves at AUTH (454), so no MAIL line is ever written. - sender_check_days, a row per UTC day, kept a year. Pages - Health: the card "Sender check", the socket's row, and the cards layout - boxes numbered by importance in two stacks read in rows; the left stack polls, the three readings of the right one are swapped in by id. - Outbound log: a refused row says why in its tag (wrong From, wrong client, rate-limited); the message's page shows the From: line and what the application may send as. - Help: topic "Sender check", word for word the mockup's. Found by the stand, fixed here: the names for the second look came from the sender bindings, and a domain with a key and no application yet was not among them. e2e: negative_journal_milter_fail_open is gone - it proved that mail passes with the panel down, which is no longer so. In its place sender_check_holds_the_from_line (another domain's From:, the hostname's, a stranger's, an address off the list, another sender in the display name - refused; own addresses - delivered) and panel_down_defers_mail (4xx with the panel stopped, the container alive, mail again after, downtime and one deferred message on Health, the card warning). Test server, this tree before the last cosmetic edits (a fixture row, a fact's size, docs): go vet ok, go test 23 packages ok, make e2e ok (337 s). Locally after them: internal/web/view ok.

panel-notifications: findings of the technical and security reviews
test / test (push) Canceled after 0s
Neither review (read-only agents, Opus and Fable, over 972a9f8..400aa76) has a Critical finding. Both found the same serious one, and more: - The notification about refused mail was built on what a rejected row says of itself. Its domain is the one in MAIL FROM, which the client typed and Postfix has not yet held against the login when the milter refuses: an application over its limit could have had the panel write a message per made-up domain, to another tenant's users among others. And the same status is written when an application is refused for its client address, which is no limit. Refusals are now counted by the domain the login is registered under, only for logins that exist and only while a limit is set on the login or its domain; one subject per sending domain. They are read through a partial index of their own (migration 0005): the query walked the whole send log every minute. - Account and user e-mails were checked with the DMARC report validator, which refuses Gmail and the like - the owner's own kind of address. A new validate.AccountEmail accepts them and refuses a local part beginning "-". - "Said" now means sent: what arises while nobody can be told, or while Postfix does not take the message, is told at a later check. Its ending with nobody left to tell is simply over. - Two DNS checks must be 45 minutes apart as well as two: the last check before a restart and the first after it were minutes apart. - The notifier's own mail waiting in the queue, and its bounce coming back to postmaster@ this server, are not the queue's subject. A listing cut at its size limit or with a line too long to read is no listing; postqueue -j gets 30 seconds. - The tables must name the selector the panel shows, not only have the line. - An a/mx lookup that did not answer inside the SPF check made the record "not authorising"; it is "cannot tell" now, for the pages too. - A ceiling of 60 messages an hour; a pass stops between domains when the process is asked to stop; sendmail gets a WaitDelay; days are rounded as a person counts; a failed read of the switch shows it on, not off. Recorded as accepted in security.md, with a roadmap candidate (from-header-binding): an application can have a message signed as the server's own name - or, as always, as another registered domain - by writing it into the From: header, which nothing holds against the login. Left as found: a recipient whose copy failed while another's went out is not tried again; a certificate that lives under 14 days is reported at each renewal. On the test server, for this tree: go vet clean, go test ./... 23 packages ok, make e2e ok (326 s). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

delivery-log-storage: findings of the technical and security reviews
test / test (push) Canceled after 0s
Neither review (read-only agents, Opus and Fable, over ae06d8b..815236a) has a Critical or High finding. What they found and what was done: - A stranger on port 25 could grow the table: every queue-id line of inbound mail was stored and pruned an hour or more later, his own message-id among them. The tailer now leaves out the lines of a queue id that postfix/inbound/smtpd opened, until qmgr removes the message or another listener opens one under the id; 4096 such ids are remembered. - A commit, so a disk sync, per stored line on the connection the journal milter shares, and a backlog written line by line. Lines are now written in one transaction per pass over the log, 500 at most, before the read offset is saved (InsertSendLogLines; follow() calls the keeper's flush). - The prune asked the send log once per line and ran hourly. It asks once per queue id and runs at start and with the six-hourly sweep; with port-25 mail left out there is little without a row to wait for. - The 4096-byte cut could split a character; it keeps characters whole. - security.md did not say that a backup now carries these lines, and the plan said the time window excludes a reused queue id where it only limits the chance to the row's queue lifetime. Both are corrected; the collision is recorded as an accepted risk with its trigger. - Tests that did not prove their comments: the prune is now tested with the sweep, a rejected row next to the prune, batching and the change from catching up to following, port-25 mail left out and its id reused. Left as found and written down in the plan: lines the tailer never reads (a file rotated away while the panel was down), and a message in the queue across the upgrade, which shows only its later lines. On the test server, for this tree: go vet clean, go test ./... 22 packages ok, make e2e ok. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

delivery-log-storage: a message's page reads its stored lines
The Delivery log box on a message's page was filled by searching the current
mail.log on every view; that file is rotated daily, so the box was empty for
anything not sent today. deliveryLog now asks the store for the row's lines -
its queue id, dated within the row's queue lifetime plus a day
(RetryPolicy.LongestLifetime) - and shows the latest 200, oldest first.
When nothing is stored the page still searches the current file, which is
what shows a message accepted before 2.2.0. When that finds nothing either,
the note no longer blames rotation for the ordinary case: it says lines are
kept with the row since 2.2.0. The Outbound log help topic in help.go follows

inbound-antispam-panel: three things the reviews left as found
test / test (push) Canceled after 0s
The owner asked for them to be put right (2026-10-12).
- A refusal is not logged twice after an unclean stop. The tailer
saves its place every five seconds, so on start it reads some
lines again; for the lines it reads on start a row is written only
if the same row is not there already (store.InsertInboundSpamOnce:
same moment, client, sender, recipient, decision, engine, detail).
Lines read as they are written are always new, so two identical
refusals in one second stay two rows.
- The Inbound log offers Deny / Allow sender only for a sender the
lists would take (inbound.Listable): an envelope sender may be
spelt in ways the form refuses, and the link led to a refusal.
- A network of one address is stored as the address: 192.0.2.7/32
and 192.0.2.7 were two entries of one list.
Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

inbound-antispam-panel: findings of the technical and security reviews
test / test (push) Canceled after 0s
Steps 11 and 12 of docs/plans/inbound-antispam-panel.md: 12/12. Two
read-only reviews of d65d632..HEAD by different models (Opus,
technical; Fable, security), each given the code and questions, not
conclusions. Nothing Critical or High in the feature; the High the
technical review found outside it is the commit before this one.
Log tailer (internal/logtail/inbound.go):
- the reply of a refusal ends at the first "; from=<", Postfix's own,
and the HELO name after it is whatever is left. Taking the longest
reply let a HELO name that spelt "; from=<..> to=<..> proto=.."
supply the row's sender, recipient and reply - and so make a
refusal read as the deny list's;
- an address with a quote, a bracket or a space is not kept: a quoted
sender could otherwise supply the recipient;
- the journal is cut to its row cap every 500 rows written, not only
every six hours;
- a queue id is forgotten when the message is queued or the id is
opened by another listener, and a stale place in the queue of
arrivals no longer drops a live id;
- milter-hold lines are not read: the held message reaches the
journal milter, which writes its row - it was written twice.
Lists (internal/inbound/lists.go): a change of the table and the
rewrite of the files are one step under a mutex; a failed rewrite puts
a removed entry back and rewrites after taking a new one out.
Store: the row cap removes the oldest by time, as the page orders them.
Page: on a sheet a refusal's text is a Reply whatever it starts with.
Help and the guide say that an allow entry for a sender address trusts
an address anyone can claim (design commit before this one).
docs/security.md: the two reviews; the roles table gains Inbound > Log
and Filter lists; Mail path describes the milters, the tailer and the
lists; four accepted risks - the filter's verdict while it is down, an
allow entry by sender address, the list files' mode, log rows held by
domain name. The plan's stale lines (size and rate refusals, who reads
the journal) are corrected.
Left as found, told to the owner: the journal's rows after an unclean
stop may be written twice (the tailer saves its place every five
seconds); a "Deny sender" link is offered for an address the form then
refuses; 1.2.3.4 and 1.2.3.4/32 are two entries.
Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

inbound-antispam-panel: Filter lists, kind column, matches, note on a sheet
Follows the design commit before it (owner's words quoted there). The lists' tables are Value, Kind, Matched and Remove. The kind tag opens the entry's sheet: note, day added, how often it decided a message in the days the log keeps, and the last match. Matches are read off the journal on each view, nothing is stored (inbound.Lists.Usage, store.ListSpamListHits). A row counts for an entry when the list decided the message - a rejected row whose reply is the deny rule's message, an accepted row whose verdict carries the allow rule's symbol for that kind - and the entry fits the row's sender or client address the way rspamd matches it: an address whole, a domain as the sender's domain, a network containing the client (an IPv4-mapped address as IPv4). A failure to count shows the lists with "never" and logs why. For that the journal milter keeps the lists' own symbols ahead of its six-symbol cap: rspamd writes symbols heaviest first, so an allow entry's -100 came last and was cut behind any six others. The plan gains "Filter list usage": what counting from the journal implies, and - the owner asked for it in writing - the conditions under which a counter kept with each entry becomes worth a migration (the journal cut by its row cap and not by age; a short retention; counts that must outlive the journal; a slow page). multimap.conf says which of its texts SelfPost reads back. Tests: Usage over every kind on both lists and the rows that are nobody's; the milter's symbol order; the store query; the page and its sheets; a handler test from journal rows to the numbers on the page. Seen: the fixture page with a sheet open, headless Edge at 1360 px - the same as the accepted drawing. Checked on the test server, uncommitted tree: go vet ./... ok, go test ./... ok (22 packages), make e2e ok. Not seen in a real run: a count above zero. It needs an entry added in the panel, which I cannot sign in to, and then mail that the list decides; in particular the deny rule's message arriving in mail.log as the reply of a milter-reject line is what the trial with rspamc showed, not yet what Postfix logged.

inbound-antispam-panel: Inbound log, Why as a sheet; no Deny on a Postfix reject
Follows the two design commits before it (owner's decisions quoted there). Kit: a new component, Sheet / SheetRow (components.go), partials sheet_tag and sheet (components.html), its rules in panel.css as in theme.css, and its sample on the kit page next to status_tag. It is the browser's popover: no script. Inbound log: the Why column is gone; the decision tag opens a sheet with who decided, then either the filter's verdict and its symbols one a line (a detail the journal milter wrote) or the reply (a detail the tailer read from mail.log - it starts with its code), and the subject whole. The sheet's id is the journal row's. A row Postfix itself refused no longer links to the filter lists. Tests: the page fixture and view tests for the sheet's markup and content (TestWhyRows), the link rule, three Deny and two Allow on the mockup's six rows; e2e reads "Decided by" and "Reply" from the sheet and wants no sender link on the refused row. Seen: the fixture page with a sheet open, headless Edge at 1360 px - the same as the accepted drawing.

inbound-antispam-panel: Inbound > Log and Inbound > Filter lists
Step 6/12 of docs/plans/inbound-antispam-panel.md. Written by a Sonnet
subagent from the mockups, reviewed and corrected by me.
GET /inbound/log - the journal a page at a time (50), filtered by
domain, decision and day; QueryInboundSpam / CountInboundSpam with the
viewer's inbound domains as the scope. The global role reads all of it
and gets "Deny sender" / "Allow sender" links into the lists; a user
with the domain role reads the rows of the inbound domains assigned to
them, without the links. The plan said global-only for the journal;
the accepted mockup and 2.0's delegation of Inbound say otherwise -
recorded in the plan as built.
GET, POST /inbound/filter-lists and POST .../{id}/delete - global role,
404 otherwise. Add form (prefilled from the query), the two lists with
Remove as the kit's row action, and "Where the lists go" with the
filter's state and when the maps were last written
(Lists.LastWritten). A refused or duplicate entry is 422 with the
message and what was typed.
Server > Settings: "Keep inbound log rows, days" with the relay on.
Help: Inbound log, Filter lists. Navigation: Log for everyone who sees
Inbound, Filter lists for the global role (Shell.ShowFilterLists).
Status tags accept / reject / tempfail join the kit's mapping.
Tests: page fixtures for both screens, held to outlines.json; view and
handler tests (both roles, filters, paging, relay off, add / duplicate
/ invalid / delete, map file content, settings field, help). e2e reads
the journal from the page instead of the database and adds and removes
a deny entry through the panel, reading deny_domain.map after each.
Seen: both pages and Settings rendered from their fixtures and compared
with the mockups side by side (headless Edge, 1360 px) - same layout
and wording.
Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

design: in-log and in-filter-lists leave the deferred screens
Guards and mockups only, ahead of the pages (inbound-antispam-panel
6/12). The owner agreed the feature ("Следующая по дорожной карте -
inbound-antispam-panel" / "Да", 2026-10-11) and started this step
("Начинай"), so the two screens are no longer "drawn but not built":
- guard_panel_test.go: in-log and in-filter-lists removed from
deferredScreens. From here TestLegacyRatchetMatchesTheEngine wants
the engine to have both pages - red until the next commit.
- guard_routes_test.go: the four routes join routes.inbound, so they
must exist with the relay on and answer 404 with it off.
Two mockup details brought to what the kit can draw, found when the
pages were built from it:
- help: the two new topics are one paragraph with a break in it, as
every topic is (panel.css has no gap between paragraphs of a topic);
- in-filter-lists: the directory in "Files" is mono at the text size -
the kit's inline code has no small variant.
check.py: 32 screens, 0 violations; outlines.json unchanged.

backup: the panel's archive is the command's, private key included
Owner, 2026-10-11: the private key is needed, and a backup from the panel and one from the console have to be the same. The commit that made the panel's backup work skipped a file under certs/ the panel could not open - on the test server the private key, which the certificate hook leaves to root and Postfix's group. That gave an archive with a certificate and no key, and two kinds of archive. - Params.Unprivileged is gone. Nothing is left out on account of who makes the archive; the queue is out for everyone (previous commit). - When the panel cannot read a file under certs/, backup.Check says so before the download and the panel refuses with what to do on the host: chgrp 998 certs/privkey.pem && chmod 640. backup.UnreadableCert tells that case from any other failure. - 998 is the container's selfpost group, which holds the panel and Postfix. Its id was whatever groupadd gave; the Dockerfile now fixes it at the value it has always had, because an operator addresses it by number from the host. - Guide: method 1 is the same archive as method 2, with the permission the key needs and a note for whatever renews the certificate. Help and the box follow the design commit before this one. - e2e: the restore scenario first makes the key unreadable and expects the refusal naming the file and the way out, then takes the backup and expects the key in it; nothing is put back by hand before the restart. go vet ./internal/backup/ ./internal/web/handlers/: ok go test ./internal/backup/ ./cmd/... ./internal/web/...: ok make e2e on the test server: ok Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

backup: no full backup holds the Postfix queue
Owner, 2026-10-11: the queue goes out of the command's archive too. The commit that made the panel's backup work left the queue in the archive of selfpost-backup, which runs as root and can read it. But that copy was never the queue: the archive is made while the instance runs, Postfix moves messages between the queue's directories all the time, and a message on its way could be in the archive twice or not at all. One rule now - QueueDir is left out of every archive - and Params.Unprivileged is only about a certs/ file the panel may not open. What is not carried over is mail still waiting for delivery; a restored instance builds an empty queue (the e2e restore scenario starts one). To keep the queue: stop the instance and tar the project directory, as the guide's methods 3 and 4 already describe. Guide: the description of a full backup, methods 1 and 2 and the comparison table.

backup: the panel's full backup works, without the queue
Found by the e2e restore scenario of the next commit: the Full backup button answered 200 with ten bytes. The archive includes the Postfix queue, Postfix keeps every queue file and directory readable by its own user alone (not configurable), and the panel runs as its own user - the walk stopped at /data/postfix/queue/active with "permission denied" after the headers were out. So since the queue moved under /data in 1.3.0. Confirmed on the test server: selfpost-backup as root makes the whole archive, the same command as user panel fails the same way. Owner, 2026-10-11: the panel's archive comes without the queue. - backup.Params.Unprivileged: the queue is left out, and so is a file under certs/ that cannot be opened (the private key on the test server is root and Postfix's group only), named through OnWarn. The selfpost-backup command leaves it unset and takes both, as before. - backup.Check reads through everything Create would archive, writing nothing. The panel runs it before the first byte: a failure is a message on the page, not a download cut short. - The box, Help (design commit before this one) and the guide say what the panel's archive leaves out; the guide's comparison table has rows for the queue and the private key, and tells to put the key back before starting a restored instance. go vet ./internal/backup/ ./internal/web/handlers/: ok go test ./internal/backup/ ./cmd/... ./internal/web/...: ok make e2e on the test server, with the restore scenario: ok Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

dmarc: a report is bounded, kept per domain, and ingested one at a time
Security review of the DMARC report path (Fable, 2026-10-11), which ran for the first time in 2.0.0. No Critical or High finding. Fixed: - Medium: a report was bounded only as 8 MiB of XML - some 160 000 records or one name of megabytes, all of it rows and table cells. At most 5 000 records (more is ErrRejected, dropped), text fields cut to 255 bytes on a character boundary, a record's count capped. - Medium: the cap of 500 reports was for the whole server, so a stranger filing under one domain's address evicted every other domain's reports. PruneDMARCReports counts per domain. - Low: the pipe service ran up to default_process_limit (100) commands at once against the panel's database; maxproc is 1. - Low: the reason logged for a dropped message carried the sender's bytes (header line, zip entry name) as they came; cut to 200 bytes and reduced to printable ASCII, zip entry names quoted. - Low: SELFPOST_DATA_DIR / SELFPOST_DB_PATH with whitespace or "$" would reach the command through export_environment as another path; refused at start when DMARC ingest is on. Left as they are, told to the owner: the parse-failure count is a lifetime figure shown under "This week"; a report larger than the command reads is dropped as unreadable; nested multipart is not searched. The hub's Retention line follows the design commit before this one. security.md: the review, and the accepted-risk entry says what a stranger can and cannot do now.

panel: show/hide rules reach a form that arrives in an htmx swap
initShowWhen bound a change listener to each control it found at DOMContentLoaded, so a form swapped in later would have been neither synced nor wired. The rules now listen once on the document and are applied again on htmx:load. No form arrives by a swap today; the roadmap row that recorded the gap is struck. Checked in a browser on the application form: the rate-limit select toggles the manual and auto fields as before, and a copy of the form put into the page with htmx.swap is synced on arrival and follows its select. go vet and go test ./internal/web/... pass.
