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-notifications: findings of the technical and security reviews
test / test (push) Canceled after 0s
Neither review (read-only agents, Opus and Fable, over 972a9f8..400aa76) has a Critical finding. Both found the same serious one, and more: - The notification about refused mail was built on what a rejected row says of itself. Its domain is the one in MAIL FROM, which the client typed and Postfix has not yet held against the login when the milter refuses: an application over its limit could have had the panel write a message per made-up domain, to another tenant's users among others. And the same status is written when an application is refused for its client address, which is no limit. Refusals are now counted by the domain the login is registered under, only for logins that exist and only while a limit is set on the login or its domain; one subject per sending domain. They are read through a partial index of their own (migration 0005): the query walked the whole send log every minute. - Account and user e-mails were checked with the DMARC report validator, which refuses Gmail and the like - the owner's own kind of address. A new validate.AccountEmail accepts them and refuses a local part beginning "-". - "Said" now means sent: what arises while nobody can be told, or while Postfix does not take the message, is told at a later check. Its ending with nobody left to tell is simply over. - Two DNS checks must be 45 minutes apart as well as two: the last check before a restart and the first after it were minutes apart. - The notifier's own mail waiting in the queue, and its bounce coming back to postmaster@ this server, are not the queue's subject. A listing cut at its size limit or with a line too long to read is no listing; postqueue -j gets 30 seconds. - The tables must name the selector the panel shows, not only have the line. - An a/mx lookup that did not answer inside the SPF check made the record "not authorising"; it is "cannot tell" now, for the pages too. - A ceiling of 60 messages an hour; a pass stops between domains when the process is asked to stop; sendmail gets a WaitDelay; days are rounded as a person counts; a failed read of the switch shows it on, not off. Recorded as accepted in security.md, with a roadmap candidate (from-header-binding): an application can have a message signed as the server's own name - or, as always, as another registered domain - by writing it into the From: header, which nothing holds against the login. Left as found: a recipient whose copy failed while another's went out is not tried again; a certificate that lives under 14 days is reported at each renewal. On the test server, for this tree: go vet clean, go test ./... 23 packages ok, make e2e ok (326 s). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

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> |
