panel-dkim-signing stage 2: OpenDKIM removed
test / test (push) Canceled after 0s
The panel's signer is the only one. Gone: the opendkim package and its
configuration, the syslog-relay and opendkim programs, /dev/log and
/run/opendkim, the reload by USR1 through supervisord
(internal/supervisor/supervisor.go), internal/syslogrelay, the port of
OpenDKIM's From: parser (internal/milter/mailparse.go and its probe,
harness and test/upstream scripts), OPENDKIM_SOCKET and OPENDKIM_DIR.
Keys: internal/domain/keys.go (Keys, NewKeys, DKIM_DIR=/data/dkim) keeps
the keys and writes a selector table, /data/dkim/selectors ("<name>
<selector>"), which the signer reads in place of the KeyTable - it reads
no database, as the sender check reads none. The table is written before
the signer serves (EnsureServerSigned moved there from the notifier).
Keys and table 0600, directories 0700, the panel's. The entrypoint copies
/data/opendkim/keys once, as the panel user, into /data/dkim.new renamed
when whole, and stops the start if the copy fails; /data/opendkim is left
for a rollback to 2.7.x.
Sender check: one RFC 5322 address as a mail program reads it, held
against the bindings; the 256-byte refusal and the texts naming OpenDKIM
go. Allowed() folded the domain through strings.ToLower, which makes the
Kelvin sign a "k" - the comparison with OpenDKIM's reading had hidden it;
it folds ASCII only now.
Health: two dkim-signer rows (applications, notifications) in Milter
sockets, opendkim out of the liveness set; the card no longer takes any
row with a note for the spam filter. Texts as in the design commit.
KILL stays in deploy/docker-compose.yml: measured on the test server,
root without it cannot signal a process of another uid - supervisord
stopping the panel, Postfix's master its children. The plan's "only use
was the reload" was wrong; the comment now gives the real uses.
e2e: one signature, the panel's, verified by dkimpy; the /data/dkim modes;
the OpenDKIM log and process checks, testNeverSignedForAnother and the
cited opendkim, libopendkim11 and libmilter1.0.1 go.

health: sockets dialled, the certificate Postfix serves, "deferred" only for the queue
test / test (push) Canceled after 0s
Audit 2026-10-12, stage 2c, "Health says what is served"; the pages of
ea8b6bf's mockup.
Sockets (A-38). A unix socket's file outlives a killed OpenDKIM or panel
and refuses every connect() (unix(7)); Health said "Listening" from a
stat. CheckSocket and CheckMilter's unix case now dial: refused is
"Nothing listens on the ... socket: the program that made it has
stopped", EACCES is unknown (the panel may not connect), anything else
"does not answer". The probe closes before a byte, which no milter logs:
libmilter takes the EOF as SMFIC_EOF without a line (sendmail
8.17.1.9-2+deb12u2, the image's libmilter1.0.1, libmilter/comm.c
mi_rd_cmd(), engine.c mi_engine() - its source is now in dev/upstream),
OpenDKIM's mlfi_close() has no connection to free, go-milter v0.4.1
returns quietly on io.EOF (session.go, HandleMilterCommands()). The page
polls every 5 s while in view, so this mattered.
Certificate (A-65). Postfix serves build/postfix-config.sh's copy,
refreshed by cert-reload every TLS_RELOAD_INTERVAL_SECONDS. The panel now
reads smtpd_tls_cert_file from postconf -h at its start (as the retry
policy) and TLS_RELOAD_INTERVAL_SECONDS; CheckServedCertificate checks the
served copy and, when the mounted file differs byte for byte (cert-reload's
own cmp -s), names it as Renewal: its expiry and mtime, two facts on the
card. Waiting is fine for the interval: a nearing expiry of the served one
is then no warning (an expiry still an error); past interval + 1 h it is a
warning pointing at cert-reload's lines. The notifier sends no expiry
notice while a renewal waits on time.
Wording (D-P1, D-P3, and the same for the spam filter): Sender check
note, help topics sender-check, upstream, filter, certificate - word for
word as in the mockup; the filter row's detail too.
Tests: stale socket file (Linux) refused for CheckSocket and CheckMilter;
CheckServedCertificate (same, waiting, late, expired + waiting, no served
path); intervalText; the card's facts; the notifier quiet while a renewal
waits, speaking once it is late. Stand (2026-10-15, make e2e, exit 0):
new health_shows_what_is_served - the three sockets dialled ok by the
panel's user; a certificate mounted without its key is refused by
cert-reload ("do not belong together") and the card shows the served
expiry, "Renewal expires" with the mounted one's, "Renewal mounted", and
"Postfix still serves the certificate above."; a matching pair is then
served again. go vet and go test ./... pass on the server (24 packages).

panel-redesign: the spam filter's socket is one of the milter sockets
The owner's decision of 2026-10-10, as the plan has it (Who sees what:
for the global administrator the filter's socket is one of the milter
sockets on Health and Overview). Written by Sonnet, reviewed by Opus.
- internal/health: CheckMilter probes an address in Postfix's two
forms. unix:/path is the existing stat; inet:host:port is a TCP
dial with a 1 s cap, closed at once, nothing written. An address in
neither form is reported as not checkable, never as fine. Details
are plain sentences ("No answer from antispam:11332 within 1 s.",
"Connection to ... refused.", "The name ... could not be
resolved.") and never the Go error text.
- Health: with the filter on, a third row "Spam filter - inbound"
with the configured address; it counts in the socket status and in
Overview's Milter sockets card. A filter that does not answer is an
error when INBOUND_ANTISPAM_MILTER_ACTION is tempfail (inbound mail
is deferred) and a warning otherwise (mail goes through
unfiltered), and the row says which. With the filter off nothing
changes.
- Both pages are global-only; a test checks a domain administrator
never receives the address.
The dial runs with the other checks on every request and poll of
Overview and Health (5 s active, 30 s idle, none while the tab is
hidden): a dead filter costs a poll at most 1 s, and a live one sees a
connect-and-close at that rhythm per open tab.
Not changed: fixtures and screenshots (the mockup draws two sockets),
help texts. The CHANGELOG line comes with the documentation step, which
is editing that file now.
go test -count=1 ./internal/health/... ./internal/web/... ./cmd/panel
ok (seven packages)
