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.

# Optional anti-spam sidecar for inbound relay (docs/plans/inbound-relay.md).
|
|
#
|
|
# SelfPost does not ship or start an anti-spam engine. This fragment brings up
|
|
# rspamd next to SelfPost and points the inbound smtpd milter at it. Merge it
|
|
# only when you want filtering on port 25:
|
|
#
|
|
# docker compose -f docker-compose.yml -f antispam/docker-compose.antispam.yml up -d
|
|
#
|
|
# Requires INBOUND_RELAY_ENABLE=true in .env. The milter sees the real client
|
|
# IP, HELO and PTR — unlike the upstream, which only sees SelfPost's address.
|
|
#
|
|
# Pin the rspamd tag the same way the SelfPost image is pinned; bump it
|
|
# deliberately. Default milter action is fail-open (accept) so a down sidecar
|
|
# does not block backup-MX. Set INBOUND_ANTISPAM_MILTER_ACTION=tempfail to
|
|
# defer instead.
