panel-dkim-signing stage 2: OpenDKIM removed
test / test (push) Waiting to run
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.

design: panel-dkim-signing stage 2 - the pages without OpenDKIM
Health: the opendkim process row goes; the Milter sockets card shows the panel's signer on its two sockets, dkim-signer · applications (sign.sock) and · notifications (sign-local.sock) - Q3 of the plan; Configuration says it reloads Postfix. Domain delete: "stop signing mail as the domain" for the OpenDKIM reload. System log: mail.log is Postfix's log (OpenDKIM never wrote to it), its sample line goes. Message page: the sample's OpenDKIM line becomes a qmgr line. Help, sender check: the From: line is read as a mail program reads it and must be one address; DMARC holds the signature to it; the sentence the mockup carried twice is once. Overview: 5 of 5 sockets. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

docs/assets/panel-ui (the 1.x experiment, superseded by the redesign) and
docs/assets/panel-redesign/{a,b,c} (the three stage-1 directions; C was
taken) are history - the plan says so - and nothing builds, checks or

panel-dkim-signing stage 1: the panel's DKIM signer, beside OpenDKIM
internal/milter/sign.go: a milter on two sockets (cmd/panel/signer.go): sign.sock for 465/587, the key of the domain the SASL login belongs to (Bindings.DomainOf, the sender_login_maps Postfix reads), and sign-local.sock for the panel's own sendmail(1) mail, the server's name. go-msgauth/dkim v0.7.0, relaxed/simple, OpenDKIM's dkim_should_signhdrs[] (libopendkim/dkim.c:223-246) in message order plus From once more; keys and selectors from the KeyTable the panel writes, a key path outside the key directory refused; strict - whatever cannot be signed is deferred. From the sources: Postfix 3.10.13 milter8.c:2329-2400 hands a folded header \n-separated, so the signer joins its lines with CRLF; inserts are 1-based in cleanup_ins_header() (cleanup_milter.c:1193), so index 0 is the top, where OpenDKIM puts its own (opendkim.c:3673). go-milter v0.4.1 calls no Abort when a connection ends, so a watchdog closes go-msgauth's streaming signer after an hour and a late end of message is deferred. Postfix: smtpd_milters = sender check, signer, OpenDKIM, journal; non_smtpd_milters = the signer's local socket, OpenDKIM - both sign every message until stage 2. disable_mime_output_conversion=yes (default off, mail_params.h:3088): an 8-bit message is no longer re-encoded after it is signed. Tests: unit tests sign and verify folded, tab-led and space-free headers, an added From:, a changed body, two messages on a connection, odd bodies, and five cases deferred. e2e: the sink image has python3-dkim (dkimpy 1.1.8-2) and the stand's DNS; on an application's message and on a notification the two signatures must agree on h=, bh=, c=, s=, a= and each must pass dkimverify. On the server: make e2e exit 0 (714 s), go vet + go test 27 packages ok. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

release: 2.7.0: base-trixie - Debian trixie, Postfix 3.10.13
Cut without asking, as the owner said on 2026-10-15. The image runs debian:trixie-slim with Postfix 3.10.13, libmilter 8.18.1, OpenSSL 3.5; every citation re-read against the trixie sources. smtpd_hide_client_session=yes on 465/587 (owner's decision). The selfpost group is 10998 and the panel 10999:10999, outside the system range; the entrypoint re-owns /data by name. The panel's database is 0600; the entrypoint removes symbolic links the panel could leave under /data. Commits |

plan: panel-dkim-signing, the draft with three open questions
test / test (push) Waiting to run
The signer in the panel's milter with go-msgauth/dkim v0.7.0 (sign.go read: streaming NewSigner, HeaderKeys over-signing, last-first picking), relaxed/simple, OpenDKIM's dkim_should_signhdrs[] plus From, the key by the login's domain and by the server's name for local mail, strict. From Postfix 3.10.13 milter8.c: multi-line headers come \n-separated, so the signer rebuilds them with CRLF. disable_mime_output_conversion=yes, unset until now. The oracle dkimpy (python3-dkim 1.1.8-2 in trixie). Three stages, 2.8.0. Open for the owner: where the signer runs, the key directory's name, Health's label.

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.

design: help - the selfpost group is 10998 (base-trixie)
The private key in certs/ is given to group 10998 on the host, no longer 998: in the trixie image systemd's packages take ids in 100-999, and 998 is systemd-network on the test server's host.

port 25 ends DATA only at CRLF.CRLF: smtpd_forbid_bare_newline=normalize (port25-bare-newline)
Postfix 3.7.11 leaves its 2023 SMTP-smuggling defence off (default "no" before 3.9, src/smtpd/smtpd.c:807), and the inbound relay's smtp/inet listener did not turn it on: a "." line ended by a bare LF ended DATA and what followed was read as the next transaction. The listener now sets normalize (bare_lf_mask_table, smtpd.c:1656; the DATA loop drops such a "." line, 3649-3652), the setting Postfix recommends and 3.9's default. The submission ports keep the default (own-mta-builds, section 5). Tests: e2e inbound_bare_newline_is_one_message sends the smuggling sequence over raw SMTP (net/smtp's DotWriter would rewrite the bare LF) and finds one message at the upstream with the smuggled part inside; port25 config check asserts the parameter on smtp/inet. On the server: make e2e exit 0 (511 s), go vet + go test 27 packages ok. Docs: CHANGELOG [Unreleased] Security, security.md, architecture.md, guide.md; roadmap: port25-bare-newline, base-trixie and panel-dkim-signing agreed by the owner in this order.

roadmap: own-mta-builds analysed - no own builds; three rows proposed instead
test / test (push) Canceled after 0s
docs/own-mta-builds-2026-10-15.md weighs patched builds of Postfix and OpenDKIM against what the panel works around. No Postfix limit needs a patch (the panel reads it through the interfaces it offers); every limit worked around is OpenDKIM's, a project with no release since 2018, three 2026 CVEs open in every Debian suite and no one answering (read in dev/upstream: dkim_process_set runs on a tenant's DKIM-Signature header in signing mode too). Bookworm is in LTS since 2026-07-12 and its Postfix 3.7.11 lacks the June, August and September 2026 upstream security batches, which carry no CVE ids. Proposed as candidates: port25-bare-newline (smtpd_forbid_bare_newline defaults to no on 3.7; our smtp/inet block does not set it), base-trixie (postfix 3.10.13; 331 citation lines to re-read), panel-dkim-signing (go-msgauth/dkim in the panel's milter; OpenDKIM, the syslog relay and the parser port removed, about 1,500 lines).

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.

Postfix takes TLS 1.2 at least, the client too where TLS is required; VRFY off; the banner without the distribution; the start refuses a rate, size or milter timeout that is not a number, under its minimum or past an int (L31).

audit 5: findings of the two reviews
- The e2e's numeric-settings test ran a container that passed every gate
and never ended: the good values are checked beside a bad one after
them; each run is named, bounded to a minute and removed.
- The gates refuse a value under the parameter's minimum (a zero window
kills anvil, a zero milter timeout smtpd) and one past an int, in
seconds for a time value (src/global/conv_time.c, src/anvil/anvil.c).
- OpenDKIM waits, five seconds at most, for the relay's socket.
- The relay marks its lines `syslog: `, writes control characters out,
reads into a queue at once and drops past 200 lines a second, saying
how many (security F1, F2; a stuck relay would hold OpenDKIM in
syslog(3)).
- smtp_tls_mandatory_protocols >=TLSv1.2 too.
- extract-cert.sh keeps the old files' group and sets its trap before
mktemp.
- crashexit spares cert-reload; architecture.md "four times running" and
what else exits the container; security.md the restart after five panel
exits and the /dev/log socket.
- Measured against the technical review: smtpd has the selfpost group
(Groups 104 998), so it did reach the supervisor socket before this
stage.
Accepted, reasons in the plan: the logrotate state file in the postfix
user's directory, envdoc_test's reading of `${VAR:-}` only, crashexit's
window pruning untested.
Tested on the test server: go vet + go test of 27 packages, make e2e (all
pass, 592 s) on this tree.

audit 5: the supervisor socket the panel's alone, OpenDKIM logs and oversigns From
test / test (push) Canceled after 0s
M17: the supervisord control socket is root:supervisor 0770, a group whose one member is the panel; OpenDKIM and Postfix keep `selfpost` for the files under /data and no longer reach the socket. L30, read in OpenDKIM 2.11.0~beta2's source first: it logs through syslog(3) only and has no Logfile option, and nothing in the container served /dev/log. internal/syslogrelay (the panel binary with -syslog-relay=/run/syslog/log, program syslog-relay before OpenDKIM, /dev/log a link to its socket) passes the datagrams to stdout, error and worse marked. opendkim.conf: Syslog yes, Canonicalization relaxed/simple, OversignHeaders From (RFC 6376 § 3.4, § 8.15). e2e: OpenDKIM's start line reaches the container log; every program RUNNING; DKIM verifies.

release: 2.5.4: audit stage 4 - panel behaviour
test / test (push) Canceled after 0s
Cut without asking, as the owner said on 2026-10-15. Signing in costs the same for an unknown name (M8) and ends the session the browser presented (L16); the Account password check has its own limit (L15). The HTTP server bounds the request, the answer and idle connections; the full backup moves its own deadline (L14). Monitoring refreshes are scheduled from htmx:afterRequest with a back-off and a 30 s timeout, and a lost session sends htmx to sign-in (M11). The Outbound log clamps its page (L10) and filters by status and day; the multiplier refuses NaN (L11); a rate-limited refusal is red (L18); Recalculate asks before it drops an unsaved edit (L19); Reload configuration writes what a restore writes and removes the keys of deleted domains (L13, L17). The cards layout orders by number. A notification is owed to each recipient (migration 0011). A DNS outage is unknown, each resolver with its own time (M14, M15). DMARC reports too large are refused for their size. An inbound upstream has one TLS mode, changed for all its domains (L5). Plus the findings of both reviews ( |

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.

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> |

On a phone the stylesheet ordered a cards box by its place in its stack, four to a stack; a fifth box got no rule and landed out of place with nothing failing (owner, 2026-10-13). Each box of the layout carries its number as data-order, and theme.css orders by it, up to twelve: an attribute, since check.py refuses classes the pages do not use, and not a style, which the CSP forbids.

L17: past DeleteDomain both rebuilds run, their errors joined under domain.ErrDeletedIncomplete; the key is removed only when OpenDKIM's tables were rebuilt (they may still name it otherwise); the domain list says the domain is deleted and that Reload configuration finishes it, not "internal error". Tests in domain (the tables failing, the sender map failing) and handlers. The Outbound log's status and day filters (owner, 2026-10-13; the mockup first, |

design: the Outbound log filters by status and by day
The status list is the statuses of a row - queued, sent, deferred, bounced, rejected, the last the three kinds of refusal together (owner, 2026-10-13). The mockup's own list was wrong: it offered rate-limited, a reason, and had neither queued nor rejected. And the days, from and to, the Inbound log's control.

audit 4: log paging at its edges, NaN refused, a red rate limit, recalculation asks, reload writes all
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
however far, nonsense, an empty log asked for page 5.
- checkAutoMultiplier is "not within", so NaN and the infinities are out.
- rate-limited is red (components.go; the mockup first,

design: a refusal under a rate limit is red, as its two siblings
out-log drew the rate-limited tag grey beside wrong From and bounced in red (audit 2026-10-12, L18); it is is-danger now. The kit's status table names the red statuses as the panel does: reject and rate-limited join error, fail, mismatch, bounced (reject was in the code's list and not here).

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.

release: 2.5.3: audit stage 3 - persistence and restore
test / test (push) Canceled after 0s
Cut without asking, as the owner said on 2026-10-15: "Вопросы про резку не задавай, просто режь." A restore is ended by its Resync: the manifest stays until the first start has regenerated the maps (M1). Every archive ends with data/contents.json and the first start after a restore compares /data with it before it opens the database: half an archive, a damaged file, a journal left beside the database is refused, named. The entrypoint hands every map under /data/postfix to the panel (a restore unpacked as root left the DMARC maps unreadable - found by the review). Migration 0010: the send log's sweep, refusal-line check, level-2 count and pages each by its index, pinned by EXPLAIN tests on the statements the store runs (M2). The backup CLI refuses a missing database (M3) and a password under 12 (M5), writes -o whole, checks -decrypt's password before the output (L1), warns of what it leaves out and refuses an empty certs/ (L2). An encrypted file may ask scrypt for 128 MiB at most, r <= 64, p <= 2, and nothing may follow its last chunk (M4, L3). TRUSTED_PROXY_CIDR's bare ::ffff:a.b.c.d is one host (L4). Maps are durable across a power loss: the directory is synced (L7). Commits |

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: every per-message question of the send log has its index
test / test (push) Canceled after 0s
Migration 0010 (DDL only; 0009 went to stage 2b). EXPLAIN QUERY PLAN of
every send_log statement showed, beyond M2 as written (stage 2 had already
moved the by-domain counts onto (domain_id, created_at)):
- the tailer's sweep of open rows (every 5 min) and its count scanned the
table: partial idx_send_log_open (created_at) WHERE status IN ('queued',
'deferred'), the statuses literal in the statements, ORDER BY +id (else
SQLite walks the table in id order to skip a sort);
- AttachRefusalLine's NOT EXISTS (... refusal_line = ?1) scanned the table
for every refusal line: partial idx_send_log_refusal_line, the query
carrying the index's WHERE; its row found by idx_send_log_rejected
(status literal, +queue_id) instead of every refusal without a queue id;
- an application's level-2 count went through its domain's index:
+domain_id in appByLogin;
- a page of one domain's or one application's log sorted all of it:
idx_send_log_domain_id, idx_send_log_app_login (id order; several domains
still sort, top-N). idx_send_log_domain stays for the global filter.
The statements are constants and builders (countMessagesQuery,
peakPerHourQuery, listOpenQuery, countOpenQuery, sendLogPageQuery,
attachRefusalLineQuery, limitRefusalsQuery) and
TestSendLogQueriesUseTheirIndexes explains exactly those: the index each
must use, no SCAN of send_log, no sort where none is wanted; the literal
statuses checked against the constants. It replaces the hand-written plan
check of TestLimitRefusalsSince.
Tested on the test server: go vet + go test of 24 packages, make e2e (all
pass) on this tree.

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.

release: 2.5.2: audit stage 2c - what SelfPost relies on, read in the sources
test / test (push) Canceled after 0s
The owner's word, 2026-10-15: "Да, режем."
Every place SelfPost relies on another program was read in that program's
source, of the version the image runs, and is cited in the code (621
entries, docs/assumptions-2026-10-14.md); what the sources contradicted is
fixed: rspamd signing a sender's own verdict, the sender map's first key,
queue expiry and Postfix's time values, refusal and recipient lines as
Postfix writes them, the rotated log read until postlogd lets it go,
inbound mail over 10 MB, local delivery to an address literal, supervision
(Postfix stopped, give-ups FATAL, the reload's exit read), sasldb2 through
a copy, Health dialling sockets and showing the certificate Postfix
serves, Referrer-Policy same-origin, migrations under BEGIN IMMEDIATE,
certbot's links followed, about forty sentences of the documents, and ten
measurements on the stand. The sender check reads From: with OpenDKIM's
own parser, ported and checked against the C and against OpenDKIM's
signing; L8 is closed; an address OpenDKIM would cut short is refused.

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> |

audit 2c: the From: parser port checked against OpenDKIM's signing itself
test / test (push) Canceled after 0s
The last check of the port, and the plan's last line of stage 2c. Through
Postfix the sender check refuses most lines before OpenDKIM sees them, so
TestPortAgainstOpenDKIM (internal/milter) talks to OpenDKIM directly:
test/upstream/opendkim-probe.sh starts OpenDKIM from the SelfPost image in
a throwaway container, with keys and a refile SigningTable for three
names, and the test plays it each From: line through go-milter's client,
as a client OpenDKIM trusts (127.0.0.1, InternalHosts' default). For each
line the d= of the signature OpenDKIM adds must be the domain the port
predicts - its address, the domain cut to DKIM_MAXHOSTNAMELEN, the whole
cut to MAXADDRESS, matched against "^.*@<domain>$" case-insensitive as
dkimf_apply_signtable() matches - or neither signs.
Run on the test server, 2026-10-15 (OpenDKIM Filter v2.11.0 from the
image): 385 lines - both shared files and lines composed from display
names plain, quoted, escaped and encoded, comments nested and open,
groups, lists, brackets, source routes, domain literals and quoted local
parts, with the other sender's name and the server's in each place - 385
agree, 287 signed. The two lines padded so that, cut at 256 bytes, they
end in "@other.e2e.test" are signed by OpenDKIM with other.e2e.test's key:

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.

audit 2c: the rest the sources contradict, and the documents
test / test (push) Canceled after 0s
Code and config: - C-M7: a DMARC report's explicit <pct>0</pct> stays 0; only an absent pct takes RFC 7489 § 6.3's default 100 (Pct *int). - C-D1: docs/development.md now tables the Debian versions the citations were read at (postfix 3.7.11-0+deb12u1, opendkim and libopendkim11 2.11.0~beta2-8+deb12u1, libmilter1.0.1 8.17.1.9-2+deb12u2, libsasl2-2 and sasl2-bin 2.1.28+dfsg-10, supervisor 4.2.5-1, logrotate 3.21.0-1 - read off the image with dpkg-query, 2026-10-15); the e2e stand's new checkCitedPackageVersions fails when the image it built differs. - C-E2: the e2e zone's SOA serial only grows (CoreDNS v1.14.6's file plugin reloads on a grown serial, not on mtime); Corefile comment says so; TestZoneSerialGrows. - C-K8, C-K9: the e2e compose and stage comments say how --project-directory and .env resolve. - D-arch:154: postfix-config.sh's "Postfix insists" comment says what TLS_README advises and that smtpd reads the key as root. - B-G7: inflight.go's reservationTTL comment: a dropped client does give ABORT (smtpd_proto() -> mail_reset() -> milter_abort()); the TTL is for smtpd dying or the milter connection breaking. - D-guide:301: the nginx fragment's first-certificate command now reaches certbot (--entrypoint certbot, --standalone, port 80 free), and the renewal loop passes --webroot -w /var/www/certbot - a standalone certificate would otherwise renew standalone while nginx holds port 80 (certbot docs, "Renewing certificates": the issuing plugin is used "unless you specify other plugins or options", and options of a successful renewal are saved). The register's proposal missed that. Documents: every D-arch, D-guide and D-sec claim the register's Answers E found false or partly true, rewritten - by three Sonnet agents, one per document, then reviewed: two proposals were obsolete after this stage's fixes and not used (a bounce's From: line - extract_from = "smtp" now; "Origin: null" - Referrer-Policy is same-origin now); a stand observation the agent had dated from a commit is now tied to the e2e test that checks it; the SQLite writers paragraph describes _txlock=immediate; the log tailer's rotation paragraph describes the minute's grace; the guide's nginx steps were put in working order (links and modes before `up`, no reconfigure step). "Deferred" is kept for Postfix's queue in the guide too. guide.md's CRLF from the agent normalised. Stand (2026-10-15, make e2e, exit 0, the version gate and zone serial test included); go vet and go test ./... pass on the server (24 packages).

certbot: certs/ links into /etc/letsencrypt, mounted at the same path; the backup follows them
test / test (push) Canceled after 0s
C-A1, C-Q4, D-guide:258, :291, :722. certbot's live/<host>/*.pem are relative links into ../../archive/<host>/ (eff-certbot docs, "Where are my certificates?": point a server at them "or create symlinks"). The guide had `ln -s /etc/letsencrypt/live/<host> certs` and the nginx fragment mounted live/<host> alone: inside the container the links led into a directory it did not have - postfix-config.sh's [ -f ] false, no copy, Postfix without a certificate - and the panel's backup, reading certs/ through /selfpost-deploy, skipped links silently. Now certs/fullchain.pem and certs/privkey.pem are links to /etc/letsencrypt/live/<host>/, and /etc/letsencrypt is mounted read-only at the same path: a commented line in deploy/docker-compose.yml for the Apache scenario, mounted in the nginx fragment (./nginx/certbot-etc). The guide's steps add certbot's own commands for a server that is not root - chmod 0755 live archive, chgrp 998 + chmod 0640 the key, which certbot keeps on renewal - so the panel reads them (Health, backup). Postfix's side follows links already ([ -f ], cp, cmp, openssl). The vhost comment says the same. The backup table: links are followed by the panel's backup; a stopped tar stores them as links unless -h (GNU tar). internal/backup: addTree follows, for certs/ only, a link to a regular file and archives that file under the link's name; a link to nothing reachable is an error naming it and the mount. Tests: TestCertsLinksAreFollowed (certs/ -> live/ -> archive/, the archive holds the files; the tree gone, Check names the dangling link; Linux). Stand (2026-10-15, make e2e, exit 0): the stand mounts ./letsencrypt at /etc/letsencrypt; new certbot_layout_followed puts a new pair into letsencrypt/archive/, relative links in live/, absolute links in certs/, recreates the container: 465 serves the new serial, Health names no renewal waiting, and the full backup holds certs/*.pem as regular files with the archive's bytes. go vet and go test ./... pass on the server (24 packages); the Linux-only tests of this session run there and pass.

store: migrations under BEGIN IMMEDIATE, the version read again inside
test / test (push) Canceled after 0s
D-S3. A deferred BEGIN starts nothing until the first access (SQLite, lang_transaction.html § 2.2), and migrate() read user_version outside the transaction: after an upgrade the panel and dmarc-ingest, opening the file at once, could both read the old version, both begin, and the second applied the next migration again on the migrated file - "already exists", that Open failing (nothing damaged: its transaction rolled back). The DSN now has _txlock=immediate (modernc.org/sqlite v1.60.1, sqlite.go applyQueryParams() sets beginMode, tx.go newTx() issues "begin immediate" for any transaction not read-only), so a migration holds the write lock from its BEGIN, and migrate() reads user_version again inside it and skips one another process applied meanwhile. Test TestTwoOpensMigrateOnce: a raw connection holds BEGIN IMMEDIATE on a new file while two Opens read version 0 and queue on their first BEGIN; released, both succeed and user_version is the number of migrations. Without the fix it fails as the register said: "apply migration 0001_init.sql: SQL logic error: table settings already exists (1)". Stand (2026-10-15): go vet and go test ./... pass on the server (24 packages); make e2e exit 0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

web: Referrer-Policy same-origin; a password shown once emptied on pagehide
test / test (push) Canceled after 0s
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).
