mixandClaude Opus 5.5 fbd0acd035 audit 2c: the rest the sources contradict, and the documents
test / test (push) Canceled after 0s
Details 
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).

mixandClaude Opus 5.5 2e1544dac5 certbot: certs/ links into /etc/letsencrypt, mounted at the same path; the backup follows them
test / test (push) Canceled after 0s
Details 
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.

mixandClaude Opus 5.5 f2ad699473 supervision as supervisord does it: Postfix stopped, give-ups FATAL, reload's exit read
test / test (push) Canceled after 0s
Details 
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).

mixandClaude Opus 5.5 599149bf83 build, deploy, inbound, dmarc, backup, e2e: cite the source of what they rely on (assumptions part C) 
Comments only, no behaviour changed. Each main.cf/master.cf parameter the
build sets, the wrapper's and the reload hook's reliance on Postfix 3.7.11
(postfix-script, master.5, postconf.5, cleanup_init.c, smtpd_peer.c,
README_FILES), supervisor 4.2.5 (process.py, options.py, events.rst),
logrotate 3.21.0, OpenDKIM's config, Cyrus SASL's sasldb, rspamd 3.11.1
(milter_headers.lua, multimap, the map watcher), Docker Compose, CoreDNS
and certbot now say where that is written. Measurements already there stay
measurements ("date not recorded" where none was); hand-composed fixtures
say so.

Contradictions left for their own commits: C-P31 cleanup's size limit,
C-P42 master outside supervisor's signal, C-V5/V6 startsecs, C-V10,
C-S3/Q3 sasldb written in place, C-Q4/A1 certbot's symlinks, C-R7 rspamd
skips local clients but the signature routine does not, C-P8, C-R4, C-R12,
C-M7, C-E2, C-K8/K9, C-D1.

mixandClaude Opus 5.5 7af37654a1 cert-reload: renew Postfix's copy of a renewed certificate (audit H2) 
postfix-config.sh copies the mounted certificate and key into
/etc/postfix/tls-internal at start (root-owned, key 0600) and Postfix reads
the copy; cert-reload only ran `postfix reload` daily, which re-read the
stale copy, so a certificate renewed while the container ran expired on
465/587 with the old one.

postfix-cert-reload.sh now, every TLS_RELOAD_INTERVAL_SECONDS: compares the
mount with the copy (cmp); when they differ and the certificate and key
belong together (openssl public keys equal - a renewer writes them one
after the other), writes each file beside its target, root-owned with the
start's modes, renames it over the target, and reloads Postfix. Nothing
changed - no reload. No copy (files missing at start) - the old periodic
reload. Never exits non-zero.

e2e renewed_certificate_picked_up: writes a new certificate into the
stand's mount and waits (30 s) for port 465 to present its serial;
compose.override.yml sets TLS_RELOAD_INTERVAL_SECONDS=2.
supervisord.conf comment, architecture.md (process table, § Postfix TLS
certs, the env knob), guide (after the proxies: picked up within a day).
CHANGELOG [Unreleased], audit plan line ticked, roadmap 12/61.

Evidence: GOOS=linux go vet in test/e2e clean; the server run of the stage

mixandClaude Opus 5.5 70b4eb5585 release: stamp the image with the release's version (audit H1)
test / test (push) Canceled after 0s
Details 
The e2e gate rebuilt selfpost:e2e through compose.override.yml with its
own VERSION=e2e, and that rebuild is the image release.yml pushed: every
published image printed "e2e", and the backup/restore version check
compared a backup's version with "e2e".

- compose.override.yml: VERSION: ${SELFPOST_E2E_VERSION:-e2e}.
- release.yml: the e2e step gets SELFPOST_E2E_VERSION = the release's
  X.Y.Z; a new step before the push checks panel -version and
  selfpost-backup -version of selfpost:e2e against it.
- e2e: image_stamped_with_version checks both binaries against
  expectedVersion() (the variable, or "e2e" when unset).
- development.md, CHANGELOG [Unreleased], audit plan line ticked,
  roadmap 1/61.

Evidence: make e2e on the test server for this tree with
SELFPOST_E2E_VERSION=2.4.2-stamp - exit 0, TestE2E/image_stamped_with_version
PASS, and `docker run --rm --entrypoint <bin> selfpost:e2e -version` prints
2.4.2-stamp for panel and selfpost-backup. GOOS=linux go vet in test/e2e
clean. Published images are left as they are.

mix 656c4d4d7f release: 1.4.0: Optional inbound relay (backup-MX) on port 25 
Optional inbound relay (backup-MX / forwarder) on port 25, off by default. Mail is accepted only for domains configured in the panel and forwarded to an upstream; there are still no mailboxes. A dedicated security review of the inbound path is still open on the plan (Fable).
Added:
  - `INBOUND_RELAY_ENABLE` (default `false`): when true, Postfix listens on
  - Panel **Inbound** pages (global administrator): domains, upstream host/port
  - Optional `INBOUND_ANTISPAM_MILTER` on the inbound listener only, plus
  - Inbound rate limit (`INBOUND_RATE_LIMIT_MESSAGES_PER_IP`, default 20) and
Changed:
  - Compose publishes host port 25 even when the flag is off (nothing listens
  - Full-backup restore Resync also rebuilds inbound maps when the flag is on.

[1.3.1]
Retry policy in the panel, persistent Postfix queue, and self-contained full backups. Mail queue and delivery history show this Postfix's first retry, backoff cap, and queue lifetime. Deferred mail survives container recreate. Full backups now archive `data/`, compose, `.env`, and `certs/`; the archive layout breaks 1.3.0 flat backups (unpack those with `tar xzf backup.tar.gz -C ./data` as before). Upgrading from 1.3.0 is a tag bump; no schema migration.
