base-trixie: the image on Debian trixie, Postfix 3.10.13; Received: hidden on 465/587
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.
  Guide, backup refusal text, help (design commit 68ec8b2), e2e.
- smtpd_hide_client_session=yes on smtps and submission (owner's
  decision): Received: names no client, TLS, login or protocol; port 25
  keeps the full header. e2e checks both.
- test/upstream/opendkim-probe.sh makes keys with openssl genrsa.

Tests: on the server, make e2e exit 0 (674 s, the image built on trixie),
go vet + go test 27 packages ok. CHANGELOG [Unreleased], guide,
architecture.md, security.md, roadmap.

#!/bin/sh
# The reload the panel asks supervisord for (program postfix-reload,
# build/supervisord.conf; internal/supervisor RunOnce reads its exit status).
#
# Exit 75 says no Postfix master runs - it is stopped, or still in its start
# behind the milter wait (build/postfix-wrapper.sh) - and the master that
# starts next reads the files as they are now, so the panel takes that as
# done. Anything else is "postfix reload" itself: 0, or its failure (Postfix
# 3.10.13, conf/postfix-script:266-279, "reload": exit 1 when not running or
# when postsuper fails; src/postfix/postfix.c, a main.cf it cannot read). "master
# -t" exits 0, silently, while no master holds the lock (src/master/master.c:495-499,
# test_lock). A master that stops between the two is a failure the panel
# reports - the rarer mistake (review of stage 2c, F5). Since Postfix 3.8 the
# reload also writes "refreshing the Postfix mail system" to stderr, which
# goes to the container's log (postfix-wrapper.sh, the note on 3.8's stderr
# logging); the panel reads only the exit status.
