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.

audit 4: findings of the two reviews
test / test (push) Canceled after 0s
- Two inbound domains on one upstream could never change its TLS mode,
each save refused for the other (medium): SetTransportAs changes the
mode for every domain on the upstream when the one saving may change
them all; a domain user who may not is refused with the mode, not the
other tenant's domain name (security F1: the first version named it).
- A deletion's leftover DKIM key is removed by Resync (Reload
configuration, a restore's first start) for names no domain has.
- The backup's write deadline moves before Check.
- hasUnsavedEdit skips password and file fields and compares a multiple
select's options; htmx.config.timeout 30 s, so a refresh never answered
ends and is tried again; a failed refresh's promise is handled.
- An empty filtered Outbound log says no message matches the filters.
- The dummy bcrypt hash is made at start; a DMARC part over 8 MiB is
refused for its size like the other two limits.
- Health's Configuration box says what Reload writes (design first,

audit 4: DNS outages unknown, DMARC limits said, typed Health, one TLS mode per upstream
test / test (push) Canceled after 0s
M14, M15: queryEach gives each resolver 2 s within the check's context and asks the one that answered last first; an address or PTR lookup not answered is Unknown, an answered mismatch beside it still an error; Checker.Server keeps the last answer's addresses, so SPF does not go Unknown with it. Notifications report faults only, now tested with SPF unknown alone and beside a wrong DKIM. DMARC reports: tests of malformed XML, gzip and zip bombs, a message over the limit, the service's Resync, hosted suggestion and validation. The finding: both limits cut silently and an oversized report failed as damaged; readAtMost refuses it for its size (MaxMessage 10 MiB, moved into IngestMessage). healthReadings replaces map[string]any for Health and Overview. L5: an inbound upstream has one TLS mode - a second domain to the same [host]:port with another mode is refused, naming the first; the TLS policy map holds each next hop once. Tested on the test server: go vet + go test of 25 packages, make e2e (all pass, 631 s) on this tree. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

panel-redesign: security review of 2.0 - sessions belong to a user by id
Stage 3, step 2. Reviewed by Fable (read-only), fixed by Sonnet with a
failing test before each fix, checked by Opus. No Critical or High
finding: route authorization, tenant isolation by id, the /server/
subtree guard, output encoding and the origin check were found sound.
Fixed
- M1: a session was keyed by user name and had no link to the user. A
deleted or renamed user's cookie stayed alive (renewed on every hit,
before the user was looked up) and became a session of whoever was
later created under that name, with that account's role. The
baseline now has sessions.user_id REFERENCES users(id) ON DELETE
CASCADE; the principal is resolved by id and a session is renewed
only after its user was found. RenameSession is gone.
- M2: any user's password change deleted every other user's sessions.
It ends that user's other sessions only.
- L1: a password set on the user form ends that user's sessions (an
administrator editing their own account keeps the current one).
- L2: store, saslpasswd2 and Postfix reload errors were shown verbatim
on the application form, the inbound upstream / recipients forms and
the limit recalculation - pages a domain administrator reaches.
Validation errors (app.ValidationError, inbound.ValidationError,
store.ErrNotAutoRateLimit) keep their text; anything else is logged
and shown as "Could not save ... Check the logs and try again."
- L3: store.ListDMARCReports treated an empty domain list as "all". It
takes a scope now (AllDomains or a list; an empty list is no rows),
and the DMARC hub is open to the domain role as the plan says: the
reports of the assigned domains, without the instance-wide ingest
box. The menu entry was already shown to them and led to a 404.
- I1: /static/ answered with a listing of the embedded assets. A path
that is not a known asset is a 404.
Consequences
- The global DMARC hub lists reports of domains that were deleted
since, too.
- dev/migrate1x (not in the tree) no longer carries sessions over:
everyone signs in again after the transfer.
- docs/schema-migrations.md: the sessions row.
Recorded, not changed - for the owner:
- L4: the report-address select names the followed user and their
address to every administrator of the domain, by default the global
administrator's login name. The plan asks for it.
- L5: a delegated inbound upstream may be any host and port, loopback
and private ranges included - within the trusted-operator model; to
be listed among the accepted risks in security.md.
- L6: Account's profile is saved without the password; becomes a
requirement once password-reset mails to users.email.
- Still echoing an error's text: backup and domain import (global
only), the domain form's validation messages.
Not checked by the review: anything needing the container (e2e, real
Postfix / DNS), CSP behaviour in a live browser.
go test -count=1 ./internal/web/... ./internal/store/... ./internal/app/...
./internal/inbound/... ./internal/dmarc/... ./cmd/panel
ok (all eleven packages; dev/migrate1x also ok)

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. Full detail: CHANGELOG.md (1.4.0). |
