inbound-upstream-result: the upstream's answer in the Inbound log
test / test (push) Waiting to run
The owner, 2026-10-16: the Inbound log lacks the upstream's answer - "Не понятна судьба письма: принято, отклонено, хост не доступен"; the result in the row only, a page per message later if needed. Mockups |

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.

log tailer: the rotated mail.log read until postlogd lets it go
test / test (push) Canceled after 0s
postlogd opens maillog_file once per process (Postfix 3.7.11,
src/postlogd/postlogd.c, pre_jail_init()) and leaves it only when it
exits: at "postfix reload" master closes the service's status pipe
(src/master/master_service.c, master_restart_service() ->
master_status_cleanup()) and dgram_server_abort() exits on reading its end
(src/master/dgram_server.c). logrotate renames and creates, then runs the
reload (build/logrotate-mail.conf postrotate; logrotate 3.21.0,
logrotate.c, rotateLogSet(), after rotateSingleLog()), so lines go to the
renamed file in between, and the tailer, already on the new one, never
read them (assumptions A-33). follow() now keeps the renamed file open as a
rotatedTail and reads it on each tick for rotatedGrace (a minute, far
longer than the gap); its places are never saved as the resume point, so a
restart still reads the rotated file through readRotated. A truncated file
is not kept.
The RFC 3339 stamp goes (A-12): it was written for a maillog_file_format
said to arrive in Postfix 3.9; there is none in 3.7.11 nor in the 3.12
snapshot of 2026-09-25 (proto/postconf.proto; msg_logger.c,
msg_logger_print() keeps strftime("%b %d %H:%M:%S ")). Every fixture now
carries the stamp Postfix writes; logtail's TestMain fixes time.Local to
UTC, since the stamp is local time and this PC is UTC+3.
Tests: TestFollowReadsTheRotatedFileAfterTheSwitch (Linux: a line appended
to the renamed file after the switch reaches the store). Stand
(2026-10-14): go vet and go test ./... pass on the server (23 packages);
make e2e exit 0, delivery_log_survives_rotation included. The tested tree
was this commit plus the previous one; the CHANGELOG entry was written
after the run, and a comment's logrotate citation corrected
(rotateLogSet runs postrotate, not rotateSingleLog).

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.

inbound-antispam-panel: three things the reviews left as found
test / test (push) Canceled after 0s
The owner asked for them to be put right (2026-10-12).
- A refusal is not logged twice after an unclean stop. The tailer
saves its place every five seconds, so on start it reads some
lines again; for the lines it reads on start a row is written only
if the same row is not there already (store.InsertInboundSpamOnce:
same moment, client, sender, recipient, decision, engine, detail).
Lines read as they are written are always new, so two identical
refusals in one second stay two rows.
- The Inbound log offers Deny / Allow sender only for a sender the
lists would take (inbound.Listable): an envelope sender may be
spelt in ways the form refuses, and the link led to a refusal.
- A network of one address is stored as the address: 192.0.2.7/32
and 192.0.2.7 were two entries of one list.
Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

inbound-antispam-panel: findings of the technical and security reviews
test / test (push) Canceled after 0s
Steps 11 and 12 of docs/plans/inbound-antispam-panel.md: 12/12. Two
read-only reviews of d65d632..HEAD by different models (Opus,
technical; Fable, security), each given the code and questions, not
conclusions. Nothing Critical or High in the feature; the High the
technical review found outside it is the commit before this one.
Log tailer (internal/logtail/inbound.go):
- the reply of a refusal ends at the first "; from=<", Postfix's own,
and the HELO name after it is whatever is left. Taking the longest
reply let a HELO name that spelt "; from=<..> to=<..> proto=.."
supply the row's sender, recipient and reply - and so make a
refusal read as the deny list's;
- an address with a quote, a bracket or a space is not kept: a quoted
sender could otherwise supply the recipient;
- the journal is cut to its row cap every 500 rows written, not only
every six hours;
- a queue id is forgotten when the message is queued or the id is
opened by another listener, and a stale place in the queue of
arrivals no longer drops a live id;
- milter-hold lines are not read: the held message reaches the
journal milter, which writes its row - it was written twice.
Lists (internal/inbound/lists.go): a change of the table and the
rewrite of the files are one step under a mutex; a failed rewrite puts
a removed entry back and rewrites after taking a new one out.
Store: the row cap removes the oldest by time, as the page orders them.
Page: on a sheet a refusal's text is a Reply whatever it starts with.
Help and the guide say that an allow entry for a sender address trusts
an address anyone can claim (design commit before this one).
docs/security.md: the two reviews; the roles table gains Inbound > Log
and Filter lists; Mail path describes the milters, the tailer and the
lists; four accepted risks - the filter's verdict while it is down, an
allow entry by sender address, the list files' mode, log rows held by
domain name. The plan's stale lines (size and rate refusals, who reads
the journal) are corrected.
Left as found, told to the owner: the journal's rows after an unclean
stop may be written twice (the tailer saves its place every five
seconds); a "Deny sender" link is offered for an address the form then
refuses; 1.2.3.4 and 1.2.3.4/32 are two entries.
Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

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.
