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.

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> |

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 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.

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> |

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.

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).

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.

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).

supervision as supervisord does it: Postfix stopped, give-ups FATAL, reload's exit read
test / test (push) Canceled after 0s
C-P42. postfix-script's start-fg runs master as its child and master calls setsid() (Postfix 3.7.11, conf/postfix-script; src/master/master.c); supervisord signals the pid alone (supervisor 4.2.5, process.py, Subprocess.kill()). A stop of program postfix left master running - a restart then found "already running" - and a container stop cut Postfix off with SIGKILL. The wrapper now stays the parent of "postfix start-fg" and on TERM/INT runs "postfix stop", asking again while start-fg is still in its checks (master -t). stopwaitsecs=15. C-V6. The wrapper's give-up on the milter sockets came after the default startsecs, so it was EXITED and restarted for ever. startsecs is now MILTER_WAIT_TIMEOUT + 10, exported by the entrypoint as POSTFIX_STARTSECS and expanded by supervisord (options.py, processes_from_section(); a non-number MILTER_WAIT_TIMEOUT stops the start): a give-up is "Exited too quickly", BACKOFF, FATAL after startretries, crashexit. For those seconds after each start the program is STARTING (the healthcheck's 90 s start period covers it; the sender check counts no downtime then). C-V5. logrotate had startsecs=0, so a refused config restarted it every second for ever. startsecs=1: FATAL after startretries; crashexit reads the event's processname and leaves logrotate's FATAL on Server > Health. B-U2. "supervisorctl start" returns when a startsecs=0 program is RUNNING, not when it ends, and mapped "already started" to success. The panel now speaks supervisord's XML-RPC itself (internal/supervisor, RunOnce): startProcess without waiting, getProcessInfo until it leaves STARTING/RUNNING, exitstatus 0 or an error; a run in progress is waited out and one of its own follows. A failed reload while program postfix is not RUNNING is logged, not an error: the next master reads the files. C-V10: postfix-reload rests EXITED after a run; the e2e process check takes STOPPED or EXITED. C-P34: the dead "postfix set-permissions" branch goes - postfix check's create-missing builds the queue tree. Stand (2026-10-14, make e2e, exit 0; MILTER_WAIT_TIMEOUT=10 on the stand): new supervision_stops_postfix_and_gives_up - supervisorctl restart postfix writes postfix-script's "stopping the Postfix mail system" and leaves one master; with the panel's sockets removed, start answers "postfix: ERROR (spawn error)" (finish() sets spawnerr "Exited too quickly", onwait() reads it first) and Postfix comes up once the panel is back; a group-writable logrotate config ends FATAL with the container up; the panel's Reload configuration answers only after mail.log has "refreshing the Postfix mail system", postfix-reload EXITED. session_survives_restart sees the stop line for the container's restart. Measured: master's own "terminating on signal 15" never reaches mail.log (master TERMs its group, postlogd included, before it logs). go vet and go test ./... pass on the server (24 packages; new unit tests of RunOnce against a fake supervisord).

logtail, health, panel: cite the source of what they rely on (assumptions part A)
Comments only, no behaviour changed. Each place the log tailer, Health and cmd/panel rely on another program now says where that is written, for the version the image runs: Postfix 3.7.11 (log_adhoc(), msg_logger_print(), smtpd_whatsup(), cleanup_milter.c, qmgr_active.c, postlogd.c, showq.c, pipe.c), logrotate 3.21.0, supervisor 4.2.5, proc(5). Measurements stay measurements and say where and when; test fixtures say whether they were seen or composed. Where the source contradicts the code the comment does not bless it but names the register entry (A-8 expiry, A-12 the ISO stamp no Postfix writes, A-15 the last recipient, A-21/A-23 sasl_username, A-33 postlogd's old inode, A-38 a socket file is not a listener, A-65 the certificate served); those are fixed in their own commits.

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

from-header-binding: what the reviews had left as found, and address extensions
test / test (push) Canceled after 0s
The owner on the three things the reviews' commit left as found: can they be fixed? They can. - Downtime that crossed a UTC midnight was all booked on the day of the restart: it is cut at the midnights between (byDay). - A message with the null envelope sender - a bounce an application writes itself - left a refusal row without a domain, which no domain administrator would see: the row takes the domain the login is bound to. - A log read again after an unclean stop counted its deferrals again: while the tailer catches up, a warning no later than the last one counted is passed over. The mark is kept to the fraction of a second the log gives. And on the check being stricter than Postfix for an address with an extension (invoices+x@ passed in the envelope, was refused in the header): it makes Postfix's second try now, the address without its extension. recipient_delimiter was the distribution's default; it is set in postfix-config.sh, since the check depends on it. e2e sends one through. Test server, this tree: go vet ok, go test 23 packages ok, make e2e ok (339 s). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

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> |

panel-notifications: the notifier, its mail and the server's own DKIM key
internal/notify applies the owner's rules. Each subject has a row of state, so a thing is said once and a restart says nothing again: - DNS of a sending domain: said after two hourly checks in a row found a record wrong, said to be over after two found it right. A lookup that did not answer moves nothing; a warning (no DMARC record) is not a subject. - TLS certificate: at 14 days and at 3, per certificate. - Queue: a message older than three days, once; once more when none is. - Level-2 limit: from the rejected rows of the send log, every five minutes; at most once a day per domain and application. Global users are told everything, domain users about their domains; one message per recipient. With the instance switch off nothing is checked and no state moves. A message that could not be handed to Postfix is tried again at the next check. Mail leaves by sendmail(1) as postmaster@<hostname>, addresses after "--", no shell. For it to be believed the server's own name is signed like a sending domain: domain.Service keeps a key for it and a line in OpenDKIM's tables without a registry row, and non_smtpd_milters now names OpenDKIM. A sending domain of the same name shares its key with the server. dnscheck.ServerMail checks the name's DKIM and SPF records; postfix.QueueMessages reads postqueue -j for arrival times. The notifier is a sixth role of the panel process. Nothing in the panel shows or switches it yet. Checked on Windows: go vet clean; go test passes for notify, store, postfix, dnscheck, cmd, and domain apart from TestWriteLoadPrivateKeyRoundtrip, which fails there on file modes and always did. Not yet run in a container: whether the unprivileged panel may submit is for the e2e step. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

inbound-antispam-panel: the filter signs what it judged
test / test (push) Canceled after 0s
Closes what the security review left as an accepted risk: with the
spam filter down - it is attached fail-open - nothing removes verdict
headers a sender wrote himself, and the inbound journal recorded his
verdict as the filter's. The owner asked whether rspamd could add a
header that proves the others are ours (2026-10-12) and agreed to a
signature: a fixed mark could be written by a sender as easily as the
verdict.
- inbound.FilterKey: a key of 32 random bytes, 64 hex characters, in
/data/antispam/filter.key, made on the first start with the relay
on. 0644 like the list files beside it: the filter is another user
in another container.
- deploy/antispam/rspamd/milter_headers.conf: a custom routine reads
the key through the directory the sidecar already mounts and adds
X-SelfPost-Filter, the HMAC-SHA256 of the message's queue id, hex;
a header of that name from the sender is removed.
- internal/milter/inbound.go: the verdict headers are kept as they
are read, and at end-of-message - when the queue id is known - they
count only if the signature fits (FilterSignature, hmac.Equal). No
key, no queue id, no signature or a wrong one: the row is that of
mail nobody judged (accept, selfpost, no detail).
The signature goes on to the upstream with the mail and is of no use
there: it fits one queue id.
Tried in a throwaway rspamd 3.11 container on the test server before
the Go side was written: the routine loads, signs
(2aa1ca6d... for key 0123...cdef and queue id 4A1B2C3D5E, the value
python's hmac gives and TestFilterSignatureIsWhatTheFilterWrites
pins), removes a sender's header of the same name, and adds nothing
without a queue id.
Tests: signed, unsigned, made-up, another message's, another key's,
the sender's followed by the real one, the next message on the
connection, no queue id; the key made once, read after, replaced when
damaged, left alone by the lists. e2e: filter.key is there, 644, 65
bytes.
docs/security.md: the accepted risk is replaced by a narrower one (the
key is readable on the host); Mail path describes the signature.
Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

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.

inbound-antispam-panel: filter lists, written as rspamd maps
Step 5/12 of docs/plans/inbound-antispam-panel.md.
Store: AddSpamListEntry, ListSpamListEntries, DeleteSpamListEntry.
internal/inbound/lists.go validates and normalises an entry - sender
address, sender domain, client address or network (canonical text, an
IPv4-mapped address as IPv4, /0 refused) - and writes the lists as six
map files under /data/antispam (ANTISPAM_DIR), each atomically, 0644 in
a 0755 directory: the filter is another user in another container. All
six are written on every change and on every start with the relay on,
empty ones included. An entry whose maps could not be written is taken
back out of the table. The writer refuses a stored value with
whitespace, a newline or # in it.
The plan's allow.map / deny.map became one file per list and entry
type: to rspamd an IP map and a sender map are different map types.
deploy/antispam/rspamd/multimap.conf holds the rules; the fragment
mounts it and ./data/antispam into the sidecar. Deny is a prefilter
reject, allow a symbol weighing -100. Tried in a throwaway rspamd 3.11
container on the test server:
- with allow as a prefilter accept, an address on both lists was
accepted and an IP on both was refused - the rule that ran first
decided; with the weight, deny won in all five mixed cases;
- IPv4, IPv6, address (any case), domain (not its subdomains) match;
- a rewritten file is reread in about ten seconds, no restart;
- files that appear after rspamd started are loaded the same way.
No page edits the lists yet (step 6).
Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok - with the relay on
/data/antispam is 755 and holds the six maps, 644, empty.

inbound-antispam-panel: refused inbound mail from mail.log; retention
Step 4/12 of docs/plans/inbound-antispam-panel.md. The log tailer writes an inbound_spam_log row for mail port 25 refused (internal/logtail/inbound.go): a "reject:" line of the port-25 smtpd is Postfix's own policy; a milter-reject / milter-hold / milter-discard line of cleanup is the filter's verdict. Only a recipient at an inbound domain is a row, so "Relay access denied" for a stranger's domain is not. The row is dated by its log line; the reply text is cut to 255 bytes of printable ASCII; a reply starting with 4 is a tempfail. To tell port 25 from 465 / 587 the listener now logs as postfix/inbound (syslog_name). cleanup logs under one name for every listener, so its verdict counts only for a queue id the port-25 smtpd was seen to open (4096 remembered). Lines are matched from the head, after timestamp and host: their tail is the sender's own text. Retention: PruneInboundSpam every six hours - older than the inbound_spam_log_retention_days setting (seeded from INBOUND_SPAM_LOG_RETENTION_DAYS, 90, range 7-365), then down to 10 000 rows. The setting has no field in the panel yet. Known limits, in architecture.md: a log line names one recipient, so a message refused at end-of-message is one row; a line re-read after an unclean stop would be a second row. Checked on the test server, uncommitted tree: go vet ./... ok, go test ./... ok (22 packages), make e2e ok - the unknown recipient at the inbound domain refused on port 25 has its row (reject by postfix), the stranger's domain has none.

inbound-antispam-panel: inbound journal milter on port 25
Step 3/12 of docs/plans/inbound-antispam-panel.md. The panel serves a second milter while the inbound relay is on (internal/milter/inbound.go, socket INBOUND_JOURNAL_MILTER_SOCKET, default /run/selfpost/inbound-journal.sock). build/postfix-config.sh puts it last on port 25, after the optional antispam milter, with default_action=accept; postfix-wrapper.sh waits for its socket. At end-of-message it writes one inbound_spam_log row per recipient at an inbound domain - other port-25 recipients (DMARC report addresses) get none - and always accepts. With a filter attached it reads the verdict from X-Rspamd-Action and X-Spamd-Result (action, score, up to six weighted symbols, only what the patterns recognise, 255 bytes); without one those headers are the sender's and are not read. The plan named X-Rspamd-Score, which rspamd does not have. The antispam compose fragment mounts rspamd/milter_headers.conf into the sidecar so that it adds the two headers (checked in rspamd 3.11: both routines exist and remove a sender's own headers of those names). Store: InsertInboundSpam, IsInboundDomain. Checked on the test server, uncommitted tree: go vet ./... ok, go test ./... ok (22 packages), make e2e ok - the relayed message of inbound_relay_delivers_and_refuses has its journal row (accept by selfpost) and the DMARC report sent through the same listener has none. Not yet seen in a real run: a verdict written by rspamd reaching this milter. The e2e stand has no filter, and the test server's only inbound domain has no upstream, so it accepts no mail.

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. The roadmap no longer calls the review pending. go vet ./cmd/... ./internal/dmarc/ ./internal/store/: ok go test ./cmd/... ./internal/dmarc/ ./internal/store/ ./internal/web/...: ok make e2e on the test server (with the port-25 scenarios of the next commit): ok Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

dmarc-ingest: what is not a report this relay keeps is dropped, not retried
Owner, 2026-10-11: foreign and malformed reports are turned away. The command answered every failure with EX_TEMPFAIL, so Postfix kept a message that could never be stored and offered it again for days, each attempt adding to the parse-failure count. IngestMessage now marks those failures (unreadable as an aggregate report, a domain not sent from here, another domain's report address) with ErrRejected; the command counts one failure, writes the reason where Postfix puts it on the delivery line of the mail log and reports the delivery as done. No bounce: the envelope sender of such a message is whatever its author wrote, and the report addresses are public. A failing store is still EX_TEMPFAIL. go vet ./cmd/... ./internal/dmarc/: ok go test ./cmd/panel/ ./internal/dmarc/ ./internal/web/...: ok Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

dmarc-ingest: Postfix can run the command, and it is told the recipient
The first DMARC report to reach the test server (Google, 2026-10-11
09:41 UTC) was accepted on port 25 and then sat in the queue:
postfix/pipe: fatal: missing user= command-line attribute
postfix/qmgr: warning: private/dmarc-ingest socket: malformed response
Three things stood between an accepted report and the panel, all since
the feature shipped in 1.7.0 - no report had ever been delivered:
- The service was addressed as dmarc-ingest/unix-pipe. Its type is unix:
postconf -P answered "unmatched service_name/type" for flags=, user=
and argv= (the warnings in the container log at every start), which
are arguments of pipe(8) anyway and not -o parameters, and the service
stayed a bare "pipe". For the same reason postconf -MX never removed
it. It is dmarc-ingest/unix now, with the arguments in the service line.
- pipe(8) gives the command export_environment and nothing else, so the
command would have refused to run: it reads DMARC_REPORTS_ENABLE (and
the data directory, when it is not the default) from the environment.
Those are now named in export_environment.
- The command took the recipient from RECIPIENT, which local(8) sets and
pipe(8) does not. With no recipient the check that a report came to the
address of its own domain is skipped. It is now ${recipient} in argv,
one recipient per run.
When DMARC ingest is off the service and both parameters are removed.
e2e: every port-25 combination now asks Postfix for the service and the
two parameters (postconf -M / -h), and for their absence when ingest is
off - which is how the wrong type was found. make e2e on the test
server: ok. go test ./cmd/panel/ ./internal/dmarc/ ./internal/postfix/:
ok.

panel-redesign: Inbound domains, domain and delete on the kit; Spam filter box
Stage 2, step 5. Written by Sonnet, reviewed by Opus.
- Three pages named after their mockups: in-domains, in-domain,
in-domain-delete, with typed page data (view/inbound.go), fixtures
and tests. The engine pages inbound, inbound_domain and
inbound_delete are gone with their templates and are off
legacy_pages.txt.
- The Spam filter box (plan, Who sees what). The panel now reads
INBOUND_ANTISPAM_MILTER and INBOUND_ANTISPAM_MILTER_ACTION, with the
semantics of build/postfix-config.sh (on only with the inbound relay
on and a milter set; accept | tempfail). It reports them, nothing
more:
on Applies to / Filter (the address, global role only) / If the
filter is down (accepted unfiltered | deferred)
off one sentence; the variable is named for the global role only
The list shows "Spam filter on|off" in its head.
- Handlers pass typed data; routes, POST targets, field names,
validation and authorization (global: all inbound domains; domain
role: the assigned ones, another tenant's id is a 404; add and
delete are global-only) are unchanged. A test saves the upstream and
recipients forms untouched and finds the domain unchanged.
Left out of the mockups' Spam filter box and menu - no source before
inbound-antispam-panel (2.1): the engine name, the quarantine row, the
"refused at the door, see the log" row, the lists row, "Log for this
domain". Also "Checked N min ago" on the MX box: the check carries no
time.
Not done: the filter's socket on Health and Overview. internal/health
checks a unix socket by stat; the documented form of the filter's
address is inet:host:port and needs a dial that does not exist yet.
Differences from the mockups, for the owner:
- refusals and confirmations are the kit flash above the boxes;
- the MX tag is coloured by the check in every state; an MX that
points elsewhere shows "In DNS now";
- the lead of the domain page follows what is saved ("Not accepting
mail yet: no upstream is saved");
- the delete page lists only what the domain has;
- /help#inbound opens Help at the top until the Help step.
Evidence
- docs/assets/panel-redesign/evidence/in-domains.png, in-domain.png,
in-domain-delete.png: 1440 px wide, headless Edge, real templates
served locally with their fixtures (filter on) - NOT from the
container (no Docker on this machine).
- panel/audit.js on the three pages at 1440 and 1280: 352 texts
checked, problems: [].
- That the panel process sees the two variables inside the container
is read from supervisord.conf and entrypoint.sh, not run.
- go test -count=1 ./internal/web/... ./cmd/panel
ok internal/web
ok internal/web/auth
ok internal/web/handlers
ok internal/web/validate
ok internal/web/view

panel-redesign: paths follow the menu; Account and Server settings split
Stage 1, step 3 (plan § Routes). BREAKING: every panel URL changes and the
old paths are removed without redirects.
Routes (web.go)
- /status -> /overview; /domains -> /outbound/domains with the domain's
settings actions under .../settings/ (reports, ratelimit, export);
/deliveries -> /outbound/log; /mail-queue -> /outbound/queue; /dmarc ->
/outbound/dmarc; /inbound -> /inbound/domains; /system-log ->
/server/log; /backup -> /server/backup (import under it); /users ->
/server/users; recheck and reload under /server/health/.
- One fragment name: <page>/fragment everywhere.
- Everything under /server/ is registered through server(), which wraps
the handler in globalOnly: the subtree is guarded once, where a new
route cannot forget it. Handlers keep their own requireGlobal.
- GET / leads to /overview, /outbound/domains or /inbound/domains.
- The /account -> /settings redirect is gone with /settings.
Account and Server > Settings
- handlers_account.go: GET /account and three POSTs - profile (username,
e-mail; no password asked, as designed), password (current password,
rate-limited like a sign-in, signs out other sessions), dmarc (the
user's default: hosted / account / custom / none, each validated).
This replaces step 1's bridge through the old Settings form.
- handlers_settings.go is the instance's page only: log retention and the
read-only rate limits, global role.
- One legacy template serves both pages by a flag until stage 2 gives each
its own: a new legacy page cannot be added to the ratchet.
Still to come inside stage 1, and why @routes stays on the ratchet:
- step 4: the application routes (one POST, under the domain);
- step 5: GET /server/health.
With @routes removed by hand TestRoutesFollowNavigation reports exactly
those and nothing else - no template links to a path the router lacks.
Old templates, tests and the e2e client are retargeted. The e2e module was
edited but not run here (no Docker, and its dependency could not be
downloaded on this machine).
Tests: Account (page, profile, password, DMARC default in every mode, a
domain administrator's own row only), Server settings (saved without a
password, range, global only), the /server/ subtree answered 404 by the
router for a domain administrator with All on both lists and for no
principal.
go test ./... green except the two Windows-only failures in internal/domain
and internal/logtail.
Roadmap 13/27.
