postfix config: port 25's size limit for cleanup too, no local delivery
Port 25 says it takes INBOUND_MESSAGE_SIZE_LIMIT (25 MiB by default) with smtpd -o message_size_limit, but cleanup writes the queue file under its own limit, main.cf's - never set, so DEF_MESSAGE_LIMIT, 10240000 (Postfix 3.7.11, src/cleanup/cleanup_init.c, cleanup_post_jail(), set_file_limit(); src/global/mail_params.h). A larger message went through DATA and was refused 552 (assumptions C-P31). cleanup now gets port 25's limit as a master.cf -o when it is larger than main.cf's; 465 and 587 keep main.cf's in smtpd's own DATA/BDAT checks. /etc/postfix outlives a restart, so the override is removed with postconf -PX first on every start. An empty mydestination left one local destination: an address literal of an interface the container listens on (src/global/resolve_local.c, resolve_local(), own_inet_addr()). local_transport is now "error:local mail delivery is disabled", as STANDARD_CONFIGURATION_README's null client has it (assumptions C-P8). Stand (2026-10-14, make e2e, exit 0): inbound_relay_delivers_and_refuses sends a 12 MB message through port 25 and finds it at the upstream, and counts it among the Inbound log's rows; new address_literal_is_not_local - probe@[127.0.0.1] from an application is refused at RCPT "550 5.1.1 ... local mail delivery is disabled" (smtpd's check_rcpt_maps() rejects what resolves to the error transport; before, local(8) took it). go vet and go test ./... pass on the server (23 packages). Tested together with the next commit (the log tailer); the two touch no common file. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

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.

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

findings of the reviews of audit stage 1
test / test (push) Canceled after 0s
Technical review (Opus) and security review (Fable) of 9efc9c7..a59e3d4; reports in the session's scratchpad. Fixed: - B1 (verified bug): store.UpdateStatus read before writing in its transaction; a commit by another connection in between (the dmarc-ingest process opens the same file) failed it at once with "database is locked" and the delivery line was lost. The first statement is now a write. - R3: a delivery line updated every row of its queue id and recipient; it now updates only the newest (Postfix reuses short ids). The sweep closes by row id (QueuedDelivery.ID, CloseUnreported(id)). - R4: a contradicted sweep keeps a mark, reason "reconcile-contradicted", instead of losing which row it was. - R1: contradicted cannot see a lost line (never read late). New counter reconcile_missed: at close, the sweep looks for the row's delivery line in mail.log and mail.log.1 (QueueLines). 0007 edited - it has run on no database but throwaway stands. - R2: queued_over_lifetime cannot measure "what removing the sweep would leave" while the sweep runs; its text now says rows stuck despite the sweep, and the rule uses closed - missed - contradicted. - cert-reload (R5, R6, R7, security medium/low): both files copied to .new and the copies checked as a pair before both are renamed; acts on the copy only when postconf says Postfix reads it; a failed reload is retried next pass; umask 077; says so when the mounted files cannot be read. The e2e case asserts Postfix reads the copy, the copy equals the mount, the key is 600 root. - Security low: a recipient with a quoted local part - the journal cut "a b"@x at the space, deliveryRe cut "a>b"@x at the ">" - matched no delivery line and was closed by the sweep. cleanAddress ends a bracketed address at the first ">" outside quotes; deliveryRe takes the recipient up to the ">, " before relay= (test fixtures given the relay= every real delivery line has). - Security low: postqueue -p's error carries at most 512 bytes of output. - Nits: addDeliveryLogDay refuses a column not on its list; the truncation test checks its message. - To stage 2b (page wording, mockup-first): the history step of a bounced row says the receiving server refused it, false for a row the sweep closed. To the owner when stage 2b is reached: since M13 the "deferred" figure counts whole messages too, which "Connections turned away" would not name. Found while verifying: the e2e's main positive path failed once with "553 not owned by user app1" - an smtpd idle from before the panel's reload took the connection in the reload's second. Measured on the stand (one-off probe, not committed): sending 0, 10, 40, 110 s after the save (two seconds at the soonest) always met an smtpd started after the reload. The e2e now waits for the sender map after each application it creates (waitForSenderMap: AUTH, MAIL, RCPT, RSET - no message, no row), and the level-1 case uses it instead of its own loop. Docs: architecture § Queue reconcile, schema-migrations (rows 7 and 8, chain head 8), CHANGELOG, audit plan (stage 1 note, the measured window, a new stage 2b line: 62 lines), roadmap 15/62. Evidence on the test server for this tree: go vet clean, go test ./... 23 packages ok, make e2e exit 0 (renewed certificate, hung panel, level 1 at 49/60).

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 follows before the push.

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: guide, architecture, security; refusals looked for every minute
guide.md gains Notifications: the four things, when each is said and said again, who is told, the two switches, and the two DNS records of the server's own name that make the mail arrive. architecture.md: the notifier as the fifth role, its readings, state, recipients and sending; the server's own key in OpenDKIM's tables; non_smtpd_milters. security.md: the panel submits mail of its own - how, to whom, and what text from outside can reach a body. That text - a queued message's sender, a DNS finding - is reduced to printable ASCII and cut before it is printed. Refused mail is looked for every minute instead of every five: it is one indexed query, and a refusal is mail not being sent now. The image's note on the panel's postdrop membership no longer calls it read-side only. go test ./internal/notify passes. 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> |

milter: the level-2 limit and the client IP list hold for every message
Security fix, outside the inbound antispam feature. Found by its
technical review (Opus, 2026-10-12), reproduced on the test stand
before the fix: over an application's level-2 limit, two MAIL FROM on
one connection were answered 451 and then accepted.
Cause. Postfix introduces a client to a milter once per connection.
The milter library (go-milter 0.4.1, session.go) replaces the milter's
session after any reply that is not "continue" - a refusal, or the
accept that used to end a message. The new session never saw Connect,
so it had no client address, and both checks passed a message without
one: overLimit returned early ("no client IP to key on") and
authIPAllowed did the same. So every message after the first on a
connection, and every MAIL FROM after a refused one, skipped the
level-2 limit and an application's client IP list. In the code since
1.9.0 for the list and longer for the limit.
Fix.
- build/postfix-config.sh: milter_mail_macros carries {client_addr},
so the address comes with every MAIL FROM; MailFrom reads it (both
spellings of IPv6) in the journal milter and the inbound journal
milter.
- overLimit no longer asks for a client address: a ceiling is on a
domain or an application.
- authIPAllowed refuses an application that has a client IP list when
no address is known.
- Body replies "continue" in both milters, which lets the message
through as "accept" did and keeps the session.
The inbound journal milter had the same cause with a smaller effect:
rows of a connection's later messages had no client address.
In the same file, the checks of INBOUND_ANTISPAM_MILTER and
INBOUND_JOURNAL_MILTER_SOCKET refuse any character outside their set
first: a glob's "*" matched anything after the first characters.
Tests: a session that never saw Connect is judged by the macro, a
listed and an unlisted address, no address, not an address; the limit
with no client address; the inbound milter answers only "continue".
test/e2e sends two MAIL FROM on one connection over the limit and
wants both refused.
Checked on the test server: e2e red before the fix on exactly that
check, green after; go vet ./... ok, go test ./... ok (22 packages).

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.

backup: the panel's archive is the command's, private key included
Owner, 2026-10-11: the private key is needed, and a backup from the panel and one from the console have to be the same. The commit that made the panel's backup work skipped a file under certs/ the panel could not open - on the test server the private key, which the certificate hook leaves to root and Postfix's group. That gave an archive with a certificate and no key, and two kinds of archive. - Params.Unprivileged is gone. Nothing is left out on account of who makes the archive; the queue is out for everyone (previous commit). - When the panel cannot read a file under certs/, backup.Check says so before the download and the panel refuses with what to do on the host: chgrp 998 certs/privkey.pem && chmod 640. backup.UnreadableCert tells that case from any other failure. - 998 is the container's selfpost group, which holds the panel and Postfix. Its id was whatever groupadd gave; the Dockerfile now fixes it at the value it has always had, because an operator addresses it by number from the host. - Guide: method 1 is the same archive as method 2, with the permission the key needs and a note for whatever renews the certificate. Help and the box follow the design commit before this one. - e2e: the restore scenario first makes the key unreadable and expects the refusal naming the file and the way out, then takes the backup and expects the key in it; nothing is put back by hand before the restart. go vet ./internal/backup/ ./internal/web/handlers/: ok go test ./internal/backup/ ./cmd/... ./internal/web/...: ok make e2e on the test server: ok Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

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: 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.

entrypoint: the queue directory and pid/ stay owned by root
The recursive chown to postfix at the end of the entrypoint also takes the queue directory itself and pid/, which Postfix keeps owned by root; postfix-script logs warning: not owned by root for both at every start. They are handed back to root after the chown, as public/ and maildrop/ are handed back to postdrop. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

postfix-config: report addresses are relay recipients when the relay is on
Found by talking SMTP to port 25 of the test server once it answered again (2026-10-10): RCPT TO:<dmarc-reports+bs.mixdep.ru@selfpost.mixfed.ru> was refused with "550 5.1.1 User unknown in relay recipient table". With INBOUND_RELAY_ENABLE and DMARC_REPORTS_ENABLE both true the server's own name is a relay domain (for the reports) and relay_recipient_maps lists the relay's recipients only. smtpd_reject_unlisted_recipient applies after the restriction list, so the OK that check_recipient_access gives a report address does not help: every report was refused. The table of report addresses is added to relay_recipient_maps in that combination. Checked on the server by setting the parameter in the running container and reloading Postfix: the domain's report address is answered 250, the former server-wide mailbox and an unknown local part 550, a foreign domain and an inbound domain without recipients 554. e2e: the combined case requires relay_recipient_maps to name both tables.

postfix-config: no whitespace in the port-25 service's -o values
Seen in the System log of the test server (2026-10-10): on every
connection to port 25
postfix/smtpd: fatal: unexpected command-line argument:
texthash:/data/postfix/dmarc_recipients,reject_unauth_destination,...
postfix/master: warning: .../smtpd: bad command startup -- throttling
With DMARC_REPORTS_ENABLE=true the script wrote
-o smtpd_recipient_restrictions=check_recipient_access texthash:...,...
into master.cf. Master splits a service line on whitespace, so smtpd got
the option cut at the space plus a stray argument and died at start:
port 25 greeted nobody - no inbound relay, no DMARC reports. postconf -P
smtp/inet/smtpd_recipient_restrictions showed the cut value,
"check_recipient_access". The server's logs have it under the previous
image too (2026-10-09), so it is not from the redesign; postfix check
does not notice, and the e2e check compared the text of master.cf with
an expectation that had the space in it.
- The restriction list is written with commas only (Postfix splits it
on commas as well as whitespace).
- master_cf_set_smtp_inet_o stops the container on a value with
whitespace instead of writing it.
- e2e: for every option it checks, the port-25 case also asks
postconf -P and requires Postfix to read the same value.
Not fixed here: Postfix's start-time warnings "not owned by root" for
the queue directory and its pid/ - the entrypoint's recursive chown
again; harmless, logged at every start.

entrypoint: public/ and maildrop/ of the queue stay in group postdrop
The entrypoint ends with chown -R postfix:postfix on the queue tree, on every start, after postfix set-permissions has run. That puts public/ and maildrop/ in group postfix; Postfix keeps them in its setgid group, and postqueue (setgid postdrop) reaches the showq socket through that group only. So the panel, which runs postqueue -p as its own user, got "Connect to the Postfix showq service: Permission denied": the Queue card of Overview said "Could not be read" and the queue page showed no listing. The data directory of the test server has carried the wrong group since 2026-08-18, so this is older than the redesign - the recursive chown came with the persistent queue in 1.3.0; Postfix itself logs "warning: not owned by group postdrop" for both at start. The two directories are handed back to postdrop after the chown. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |
