mixandClaude Opus 5.5 a658da11f7 audit: stage 2c - the answers, and what they make to fix
test / test (push) Canceled after 0s
docs/assumptions-2026-10-14.md gets its second half: every entry of the
inventory settled in the source of the version the image runs, with the
citation now beside it in the code. 559 verdicts (the documents' claims
that repeat one another answered once): 415 hold, 77 hold in part, 55 do
not hold, 12 need a measurement on the stand.

The plan's heuristics line is done; what the sources contradict becomes
fourteen lines of stage 2c, worst first: rspamd signs a forged verdict for
a client it counts as local; the sender check takes any key of the sender
map where Postfix takes the first; expiry, the forced-expire flag and
Postfix's time units; refusals and recipients matched by what Postfix
really writes; postlogd after a rename; inbound mail over 10 MB refused by
cleanup; master outside supervisord's reach; sasldb written in place;
Health showing a socket file and a certificate Postfix does not serve; the
Origin check refusing every POST where Sec-Fetch-Site is missing; two
processes migrating at once; certbot's symlinks; the documents; and the
measurements. Roadmap 31/81.

mixandClaude Opus 5.5 3c8628074f release: 2.5.1: audit stage 2b - the log tailer and what the panel shows of a refusal
test / test (push) Canceled after 0s
A log rotated while the panel was down is read to its end; the deferred
counter remembers a place in the log, not a second; a refused message's
page shows what Postfix wrote; a refusal the panel did not get to write is
written from mail.log; downtime is estimated (≈) when supervisord is
silent; the Sender check card counts connections and messages apart (the
owner's decision); a message the sweep closed says the panel closed it.
Plus the findings of both reviews of the stage.

Rolled out to the test server as 2.5.0-post.e1ddf12 (the same code):
migration 0009 ran on the live database - schema 9, the new columns in
place, 68/68 send-log rows still tied to their domain, integrity ok.

CHANGELOG cut; pin 2.5.1 in deploy/docker-compose.yml, README (with the
local-build note), guide; development.md "from pin"; roadmap row and the
recommended order; stage 2b marked shipped in the plan. No tag.

mixandClaude Opus 5.5 e1ddf12744 audit: stage 2c - what was taken on trust, read in Postfix's source
test / test (push) Canceled after 0s
Owner, 2026-10-14, after the rule "do not guess how code works when its
documentation or source can be read": "Есть ли ещё у нас места, где мы
угадывали?". The inventory found four: qmgr's expiry against the queue
lifetime (a margin in queued_over_lifetime), postlogd after a rename (the
rotation window), the stale smtpd after a reload (measured, not
understood), and the NOQUEUE line's fields (two fixtures carry a
sasl_username Postfix does not write, one presented as seen on the stand).
A line in stage 2c reads Postfix 3.7.11 for them, records what is read,
fixes the fixtures and the code where they disagree. Plan 66 lines.

mixandClaude Opus 5.5 5dcff8c2b9 audit: stage 2c - the sender check reads From: as OpenDKIM does (owner's decision)
test / test (push) Canceled after 0s
Owner, 2026-10-14, after reading OpenDKIM's source together
(dkim_mail_parse, called in mlfi_eoh on the first From:; SenderHeaders is
unset in build/opendkim.conf): "Да" to porting the parser so that the check
decides by the address OpenDKIM will take. The scan of the display name and
comments for another sender of the server - a guard against two parsers
parting ways, and the reason L8 is half closed - then goes.

New stage 2c (three lines) after 2.5.1 and before stage 3: the port from
the version the image runs, checked against OpenDKIM on the stand with
generated lines, then docs and wording. Stages 3 and 4 move to 2.5.3 and
2.5.4 (development.md's planned cuts). Plan 65 lines, roadmap 30/65.

mixandClaude Opus 5.5 415334c2cc message page: a row the sweep closed says the panel closed it (stage 2b)
The History step of every bounced row said the receiving server refused
the message permanently or Postfix gave up, "the reason is in the delivery
log below" - for a row the reconcile sweep closed (reason "reconcile")
neither is known and the log has nothing (review of stage 1). Such a row's
step is now "Closed by the panel - Postfix no longer held the message and
mail.log never said what became of it ... rather than show a delivery it
cannot evidence." The help topic log names the case (design df96690).
Pictured for the owner with the real templates (dev/shots); the variant has
no mockup screen of its own, as the refused one.

Test: the page of a row the sweep closed says "Closed by the panel" and not
"the receiving server refused".

CHANGELOG [Unreleased], audit plan line ticked, roadmap 29/62.
Evidence: the message-page tests of ./internal/web/handlers ok locally; the

mixandClaude Opus 5.5 ac985d03a8 sender check: connections and messages counted apart; downtime estimated when supervisord is silent (stage 2b)
Following the design commit df96690.

- Two columns (owner, 2026-10-14): sender_check_days.messages (migration
  0009, not deployed) holds the messages deferred mid-message, from
  cleanup's warning; deferred stays the connections smtpd turned away.
  AddSenderCheckDeferred takes which; the counter passes cleanup's as a
  message. The card has "Connections turned away" and "Messages deferred";
  it warns on either within 24 hours (one mark, as before).
- Supervisord silent at start: postfixStarted asks again every 2 s for 30 s
  (postfixState: started, running, known). With no answer the downtime is
  the time since the alive mark - an upper bound - booked with estimated = 1
  (sender_check_days.estimated, MAX over a day); the card prefixes such a
  period's time with "≈ " and its note says what ≈ means. Before, such a
  start counted nothing and the number the owner decides by read low.
- Help topic sender-check and the log topic word for word as the mockup
  (help.go).

Tests: store (connections and messages apart, a period with an estimated
day); logtail (cleanup's warnings are messages); cmd/panel (supervisord
silent: the time since the mark, estimated); view fixture and the Health
page at four columns with ≈; e2e reads the row's two counts (panel down:
connections; panel hung: messages). Schema at 0009 with the columns.

schema-migrations row 9, CHANGELOG [Unreleased], audit plan lines ticked
(two), roadmap 28/62.
Evidence: go vet ./... clean; go test of store, view, cmd/panel ok locally,
logtail but for the Windows-only test; the server run follows before the

mixandClaude Opus 5.5 65d916f26a logtail: a refusal the panel did not get to write is written from mail.log (stage 2b)
test / test (push) Canceled after 0s
The sender check answers 550 5.7.1 and writes the refused row through a
buffer a moment later; a panel stopped in between (a rollout, a kill) left
an application refused and a log that did not know it. A refusal at MAIL
FROM needs nothing: the journal milter writes its row before it answers.

- logtail.refusalLines remembers each queue id's login from smtpd's
  "<id>: client=..., sasl_username=<login>" (4096 ids at most) and, on
  cleanup's "<id>: milter-reject: END-OF-MESSAGE ...: 5.7.1 From: <line> -
  <why>; from=<...> to=<...>", waits 30 s and hands it to
  store.RecoverRefusal - an INSERT ... WHERE NOT EXISTS a refused row of that
  queue id within two minutes: the row the panel wrote, or one recovered
  before, means nothing is written. It is read from the saved offset on, so
  a kill is covered as well as a clean stop - which a flush of the buffer at
  shutdown would not.
- Migration 0009 (not deployed yet) gains send_log.recovered; the row is
  written with the line's time, the login's domain id, reason "from", the
  From: line as the check printed it (to the last " - " before ";").
- The message page: a fact "Written: from mail.log after a restart: the
  panel stopped before it wrote the refusal".

Tests: store (not written when the panel wrote it; written once however
often); logtail (the login from client=, the From: line with a " - " in it,
nothing before the wait is over); view (the fact). e2e
refusal_recovered_from_the_log: a From: refusal, the panel stopped, its row
deleted and the tailer's saved place moved before the message's first line
(python3 in the container, as the panel's user - a kill cannot be timed to
that moment from outside); started again, the row is back, recovered, once.

Also fixed: handlers TestMessagePageOfARefusedMessage still expected the
old sentence; it failed on the server after e166a2e, whose run showed only
the schema failures - now it wants the new one.

schema-migrations row 9, CHANGELOG [Unreleased], audit plan line ticked,
roadmap 26/62.
Evidence on the test server for this tree but the handler-test fix: make e2e
exit 0 (the new case 37 s); go test 22/23 ok, the 23rd that test - fixed,
passes locally; the full run follows before the push.

mixandClaude Opus 5.5 e166a2ebd6 refused messages: the page shows what Postfix wrote (stage 2b, 0009)
The Delivery log box of every refused row said "This message never reached
the queue, so Postfix wrote no delivery lines for it" - untrue: Postfix
wrote a line for each. The owner, 2026-10-13: the box is required on every
message page. Pictured for him first (dev/shots, the refused variant of
out-message: wrong From with its queue id lines, rate-limited with the
NOQUEUE line); the variant has no mockup screen of its own - the guard ties
screens to pages, and its outline is out-message's.

- Wrong From: cleanup gives the message a queue id before the headers are
  judged; the sender check reads {i} at end-of-headers and writes it on the
  refused row. Its lines - stored under the id like any other's - are on the
  page, but only those from 10 minutes before to 1 minute after the refusal
  (store.SendLogLines for a rejected row): Postfix frees the id at once, and
  a later message with it lends nothing. No mail.log fallback for a refused
  row, for the same reason.
- Rate-limited and wrong client: refused at MAIL FROM, no queue id. Migration
  0009 adds send_log.refusal_line; logtail.refusalLines matches smtpd's
  "NOQUEUE: milter-reject: MAIL from ...; from=<...>" (not port 25's, not
  CONNECT/EHLO) and store.AttachRefusalLine puts it on the newest refused row
  of that sender (and login, when the line names it) within two minutes; a
  line whose row is not written yet waits up to 30 s (retried at each pass).
- The page: the queue id fact says "given, the message was not queued" or
  "none - refused at MAIL FROM, before one is given"; the box's caption is
  "The line from mail.log for this refusal" for the latter; a row from
  before says the line was not kept. LogLineLevel colours a refusal by its
  reply: 5xx red, 4xx amber (IPv6 clients included). The id in the fact is
  not muted as in the picture: the kit has no muted inline.

Tests: store (attach by sender, login, time; not a queued row, not one an
hour off; a refused row's lines are its own minutes); logtail (attach, wait
and retry, port 25 and other lines ignored); milter (the refused row carries
{i}); view (facts, caption, line levels); handlers (the line on the page,
the sentence without it). e2e refusals_show_postfixs_line: a client-address
refusal made there, and the pages of a wrong From, a rate-limited and a
wrong client refusal each show Postfix's line.

schema-migrations row 9, CHANGELOG [Unreleased], audit plan line ticked,
roadmap 25/62.
Evidence on the test server for this tree: make e2e exit 0 (the new case
in 5.4 s); go test ./... ok but for two schema tests, fixed after the run

mixandClaude Opus 5.5 c452606175 logtail: the deferred counter remembers a place in the log, not a second (stage 2b)
test / test (push) Canceled after 0s
The counter passed over, while catching up after a start, every warning no
later than the last one counted - by time; mail.log stamps whole seconds,
so a second warning of that second, later in the file, was lost.

- The tailer gives each line its place (Place: the file's fingerprint and
  the offset just past the line): follow tracks the bytes the reader hands
  over, readRotated likewise in mail.log.1. Run hands tr.line to the
  counter.
- store.AddSenderCheckDeferred(at, n, place) counts, moves the
  last-deferral mark (never back - an upsert WHERE) and saves the place
  (settings sender_check_counted_place) in one transaction.
- Catching up, a warning in the file of the last one counted is passed over
  by place (end <= counted end); in another file - a rotated log read again
  - by time, as before. The fingerprint carries the inode, so the place
  stays true across a rotation.

Tests: two warnings of one second, an unclean stop between them, all lines
read again - each counted once; the store saves the place with the count
and keeps the latest deferral time. Existing counter tests pass a zero
place (time rule).

CHANGELOG [Unreleased], audit plan line ticked, roadmap 24/62.
Evidence: go vet ./... clean; go test ./internal/store, ./internal/logtail ok

mixandClaude Opus 5.5 4678015bbd logtail: a log rotated while the panel was down is read to its end (stage 2b)
At start, a saved offset whose fingerprint was not the current file's meant
"start on the new file": what Postfix wrote between the panel's stop and the
rotation was never read - delivery statuses, stored lines, refusals, inbound
journal rows, the deferred counter.

- tracker.resume marks the case (behind, prev); follow calls readRotated
  before the new file: it opens mail.log.1 (delaycompress leaves it plain),
  checks by fingerprint that it is the file the place belongs to, reads it
  from the saved offset to its end through handle (catching up: the
  once-protections apply) and flushes the stored lines.
- Not found, not that file, or the offset past its end (rotated twice):
  logged, with the saved place's time - from when nothing was read.
- The fingerprint gains the file's identity (device.inode, fileid_unix.go;
  empty elsewhere): two logs that begin alike are two files - the
  review-2026-08-followups row on collisions. A fingerprint saved before
  (hash alone) still matches by its hash (sameLog), so the first start after
  the upgrade resumes where it was.
- store.LogtailState reads back updated_at.

Tests: stop, append, rotate, append, start - both halves read, once each,
the earlier line not again; a mail.log.1 that is another file is not read
from the place; sameLog with an old and a new fingerprint.

CHANGELOG [Unreleased], audit plan line ticked, roadmap 23/62.
Evidence: GOOS=linux go vet ./internal/logtail clean; go test ./internal/logtail

mixandClaude Opus 5.5 5be109b871 release: 2.5.0: audit stages 1 and 2 - the delivery log and the tenant boundary
test / test (push) Canceled after 0s
Stage 1: a cut queue listing no longer bounces held mail; the reconcile
sweep closes only queued rows, by id, marked "reconcile", and its fate is
measured (delivery_log_days, migration 0007); delivery lines are read at
the head of the line; a renewed TLS certificate is served without a
restart; Health counts the message a hung panel deferred.
Stage 2: logins folded to lower case and unique without regard to case;
the last global administrator kept inside the transaction, users saved
whole; a domain import held to the forms' rules; log rows by domain id
(migration 0008); the 550 reply names no other domain; which key OpenDKIM
signs with, tested. Plus the findings of both reviews of each stage.

Rolled out to the test server as 2.4.2-post.ef18ef2 (the same code):
migrations 0007 and 0008 ran on the live database - schema 8, 68/68 send-log
and 10/10 inbound rows tied to their domain, integrity ok.

CHANGELOG cut; pin 2.5.0 in deploy/docker-compose.yml, README (with the
local-build note), guide; development.md "from pin"; roadmap row and the
recommended order; stages 1 and 2 marked shipped in the plan. No tag (the

test / test (push) Canceled after 0s
security.md
- § Roles: the last-global guard is inside the transaction that deletes or
  demotes (write, then count); setup is one statement; a user is saved in
  one transaction. A log row, outbound or inbound, belongs to a domain by
  id; a domain added again starts with an empty log. The Inbound › Log row of
  the table says by id.
- § Mail path, sender check: the agreement of the check and OpenDKIM is
  tested (the shared list of passed From: lines); the refusal does not say
  which other sender a line names.
- Accepted risks: "a row of the inbound log belongs to a domain by name"
  struck (L12).

guide.md
- Domain export and import: the file is checked like the forms before
  anything is created; a login keeps its case and a case clash is refused.
- The application form: a new login is stored in lower case.

mixandClaude Opus 5.5 5747f0b25c sender check: the reply names no other domain (L8); which key signs, tested (stage 2)
L8: a From: line naming another sender of the server was refused with
"it names another sender of this server, <domain>" - a confirmation, to
whoever tries names, that the domain is hosted here. The reason now stops
before the domain; the line as written stays in the reply (the client's own
text) and on the refused message's page (header_from). Unit test: the reason
of every refusal names none of the server's other domains; e2e: the reason
of each sender-check refusal does not contain other.e2e.test.

Which key OpenDKIM signs with (owner, 2026-10-13): the check and OpenDKIM
read From: with two parsers, and their agreement was argued, never run.
internal/milter/testdata/from-lines-passed.txt holds the lines the check
passes for an application - bare and bracketed, quoted names with a comma,
escaped quotes and an address inside, an extension, three encoded charsets,
two folded lines, comments (nested too), a stranger's address in the name -
as Go-quoted strings with {domain}. The unit test wants each passed; the new
e2e case passed_from_lines_signed_for_their_domain_only sends each as app1
and wants every DKIM signature at the sink to be for the sender domain,
with one valid. All fifteen were. "(the shop) a@domain" - a comment before
the address, valid RFC 5322 - is refused by the check ("it must be one
address"); strict, not a hole, so it is not in the file. Groups are refused
too.

mixandClaude Opus 5.5 a618ffb0e4 send log: rows belong to a domain by id (audit L12, 0008)
A domain user's log, the message page, a domain's statistics, the level-2
count and the notifier's refusal count picked send-log rows by domain name,
so a domain deleted and re-added under its old name showed its earlier mail
to the next assignee and went on counting it.

Migration 0008 (not run on the live database yet, so extended here):
send_log.domain_id and inbound_spam_log.inbound_domain_id, REFERENCES ...
ON DELETE SET NULL, filled once by name from the registry as it is at
migration time, each with an (id, created_at) index.

- Writes: InsertQueued / InsertRejected set domain_id to the domain of the
  row's login (loginDomainID) - the journal milter and the sender check's
  refusal rows both go through them; the inbound journal sets
  inbound_domain_id from the inbound domain's name at insert.
- Reads: SendLogFilter.DomainIDs (was Domains, by name) and
  InboundSpamFilter.DomainIDs are the scope; the global role still reads
  everything. The message page checks row.DomainID against the user's
  domains. DomainSendStats and CountMessages keep their name argument and
  select domain_id = (SELECT id FROM domains WHERE name = ?). The notifier
  joins send_log.domain_id to the domain and its application.
- DMARC reports stay by name on purpose (a report is about the DNS name).

Tests: store - scope by ids; a re-added domain's log, level-2 count and
statistics hold its own row only, the global log both; inbound scope by
ids. Handlers - the new assignee gets 404 for the old row's page and does
not see it in the log, the global role sees both. Tests that wrote rows for
a login that is no application now register it (a row is a domain's through
its application). Schema at 0008 with the two columns and indexes.

domain.Import trusted the file for everything but the domain name, the
selector and the password: DMARCRua was not validate.Email'ed, client IPs

0 counted nothing, a garbage IP made the application refuse every client.

handlers.checkDomainImport runs in HandleImportDomain after the domain name
check and before Import, and refuses the file with "Invalid <what> in export

rate limit (parseRateLimitMode; auto - checkAutoMultiplier, 0 meaning the
default as an empty field does; manual - checkManualLimit, which the form
now uses too: count > 0, <= the level-1 backstop, window > 0; both 0 is an
export without a limit of its own), each application's client addresses
and the legacy ones on its rate limit (parseIPList, written back as the
form stores them; allow-list on with none is refused). Login, sending
addresses and password stay checked in app.ImportApplication.

Tests: a good export passes and its addresses come out normalised; nine
broken fields each refused with their message; a refused file posted to the
handler creates no domain.

mixandClaude Opus 5.5 f9e75de8d1 store: users saved in one transaction, the last global kept inside it (audit M7, M9)
M7: DeleteUser counted the global users and then deleted; the handler's
demotion and CreateGlobalUser checked and then wrote. MaxOpenConns(1)
serialises statements, not pairs: two globals deleting or demoting each
other at once could leave none. Now:
- DeleteUser: a transaction that deletes first (taking the write lock) and
  then requires a global left (requireAGlobal) - ErrLastGlobal rolls back.
- SaveUser: likewise for a demotion, the count inside the transaction after
  the write. The handler's early count stays only to answer before hashing a
  password; SaveUser decides, and ErrLastGlobal maps to the same message.
- CreateGlobalUser: INSERT ... SELECT ... WHERE NOT EXISTS (SELECT 1 FROM
  users), one statement.

M9: submitUserUpdate made five writes in a row (UpdateUser, sessions,
SetUserRole, ClearUserReach with its error only logged, SetUserReach).
store.SaveUser(UserChange) writes name, hash, e-mail, role and reach in one
transaction (a global user's reach cleared); sessions end after it commits.
The create path had the same flaw - user, reach and then e-mail in three
writes - and now goes through AddUser, one transaction; CreateUser stays as
a wrapper for its many test callers. SetUserRole is gone; writeUserReach is
the reach write inside a transaction.

Tests: store - two globals demoting, and deleting, each other from two
goroutines: exactly one refused, one global left; a refused SaveUser (taken
name, a reach to no domain, nothing assigned) changes nothing; promoted to
global loses the reach; AddUser with a bad reach leaves no user; four setups
at once create one user. Handlers (the users pages, direct): the whole
change saved, back to domain with a reach; the last global not demoted and
the typed rename not written; a domain user with nothing assigned refused,
nothing changed; create with e-mail and reach.

CHANGELOG [Unreleased], audit plan lines ticked (two), roadmap 17/62.
Evidence: go vet ./... clean; go test ./internal/store ok; the users tests of
./internal/web/handlers ok; the server run follows before the push.

mixandClaude Opus 5.5 60c7b85f84 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).

mixandClaude Opus 5.5 f51f5db245 app: logins folded to lower case, unique without regard to case (audit H4, 0008)
Postfix's reject_sender_login_mismatch compares the SASL login with the
sender map without regard to case - seen on the e2e stand this time (a
one-off probe, not committed: map rewritten to "APP1", client authenticated
as "app1", RCPT accepted). The panel stored logins as typed under a BINARY
UNIQUE, so "Ops" and "ops" were two applications to the panel and one sender
to Postfix: a tenant could send with another tenant's envelope sender.

- app.foldLogin: Service.Create lower-cases the login (owner: fold, do not
  refuse); CreateWithSettings rolls back the stored (folded) login.
- ImportApplication keeps the login as written: folding it would rename the
  SASL account and break the imported application's working credentials;
  the index below refuses a case clash there too.
- Migration 0008 (DDL): CREATE UNIQUE INDEX idx_applications_login_nocase ON
  applications (login COLLATE NOCASE). The column's own BINARY UNIQUE stays
  (SQLite cannot change a collation without a table rebuild, which a
  migration transaction cannot do with foreign keys on). Checked on the live
  installation first: 4 logins, no case clash; "Quieter3C" keeps its case.
  0008 is not run anywhere yet; send_log.domain_id joins it later in stage 2.

Tests: "Ops" created as ops, SASL account and map binding in lower case,
OPS in another domain and an imported oPs refused; the store refuses ops
beside Ops; schema at user_version 8 with the index.

mixandClaude Opus 5.5 a59e3d4d61 docs: stage 1 of the audit - log tailer, reconcile, sender check, guide
test / test (push) Canceled after 0s
architecture.md
- § Log tailer: the rotation drain does not close the gap entirely
  (postlogd writes to the renamed file until the reload reaches it); the fix
  waits for the measurement. Delivery lines read at the head of the line
  (M12).
- § Queue reconcile: reason "reconcile", the 4 MiB cap, the conditional
  close; the measurement (delivery_log_days, its four counters) and the
  decision rule written before the data.
- § Sender check, what it costs: cleanup meets a check that hangs mid-message,
  with the warning seen on the stand; counted once per message.

guide.md
- § Outbound log: `bounced` is the panel's word when Postfix no longer holds
  a message and the log never said; it is counted.
- § Overview and Health, Sender check: the message a hung panel deferred is
  counted too.

Audit plan line ticked, roadmap 14/61. Stage 1's code items are done

mixandClaude Opus 5.5 db36aa2c0e logtail: count the message a hung sender check defers in cleanup (audit M13)
Seen on the e2e stand, the panel frozen with SIGSTOP once DATA was
answered: the client gets 451 4.7.1 after 30 s, and the warning that names
the socket is cleanup's, not smtpd's:

  postfix/cleanup[1339]: warning: milter unix:/run/selfpost/sender.sock:
    can't read SMFIC_HEADER reply packet header: Connection timed out
  postfix/cleanup[1339]: 7BCAF3C75DA0: milter-reject: END-OF-MESSAGE ...
    4.7.1 Service unavailable - try again later; ...

The counter read smtpd lines only, so Health's "messages deferred" missed
the one case that tells a hung panel from a stopped one. milterLineRe now
takes smtpd and cleanup; cleanup's "milter unix:<socket>:" warning counts a
message each time (one cleanup process serves message after message, and the
first warning ends the message); smtpd keeps once per connection. The
composed fixture is replaced by the seen lines, with two messages through one
cleanup process and OpenDKIM hung in cleanup (not counted).

e2e panel_hung_mid_message_is_counted: freezes the panel after DATA's 354,
wants a 4xx at the end of DATA, logs what mail.log says, and waits for
Health's today count to grow. kill through sh -c: the image has no kill(1).

mixandClaude Opus 5.5 7af37654a1 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.

mixandClaude Opus 5.5 63520f1678 logtail: deliveryRe anchored at the head of the line (audit M12)
The pattern that writes a row's status matched anywhere in a line: a
port-25 reject line ending helo=<ID: to=<victim@...>, status=sent> parsed
as (ID, victim, sent). parseDelivery now takes the stamp off with
SplitTimestamp and matches `^host program[pid]: <id>: to=<...>, ...
status=`, as queueLineRe and the inbound patterns do.

Tests: the probed HELO line, the same text in a quoted sender on a qmgr
line, the text after an smtpd line's queue id - none parse; a syslog-stamped
line as Postfix 3.7 writes it parses. The existing cases unchanged.

mixandClaude Opus 5.5 ffefa9d6df delivery log: measure the sweep before deciding its fate (audit H3, 0007)
Migration 0007 (DDL only): delivery_log_days, a row per UTC day, kept a
year, shown nowhere - read off a copy of the database after a month by the
decision rule written in the audit plan.

- reconcile_closed: the sweep adds the rows it actually closed.
- reconcile_contradicted: store.UpdateStatus, in one transaction, counts the
  rows with reason "reconcile" a delivery line now speaks of, writes the
  log's status and clears the reason - so a re-read line counts once.
- tailer_blind_seconds: follow() tracks stretches in which the file is gone
  or reopening fails (logtail.blindness); stored when a stretch ends and
  every minute while it lasts; under 3 s not counted (the rotation's tick
  between rename and create loses nothing).
- queued_over_lifetime: every sweep overwrites the day's level with the rows
  queued past LongestLifetime + MaximalBackoff (a message Postfix still
  works on stays queued until its first retry after the lifetime).
- retentionLoop prunes days older than a year.

Tests: store (sums per day, the level overwritten, under a second nothing,
prune; a contradicted sweep counted once and its reason cleared; count of
queued rows); logtail (the sweep counts what it closed; countStuck records
the level; blindness - a one-tick gap not counted, 75 s stored as 60 + 15
from where the last part ended). Schema tests at user_version 7.

schema-migrations.md: chain head 7 (it still said 5 since 2.4.0), row 7.

mixandClaude Opus 5.5 9adb44845c logtail: the sweep closes only queued rows, with reason "reconcile" (audit H3)
reconcile() closed a row through UpdateStatus (WHERE queue_id AND to_addr),
which could overwrite a "sent" the tailer wrote between the listing and the
close, and rewrite an old row of a reused queue id. store.CloseUnreported
sets status bounced and reason "reconcile" (store.ReasonReconcile; the
0006 column, no schema change) WHERE ... AND status = 'queued'; the sweep
counts rows actually closed.

Tests: store - a queued row is closed with the reason, a sent row is left

mixandClaude Opus 5.5 dfe10f6c27 postfix: a truncated postqueue -p listing is no listing for the sweep (audit H3)
QueueIDs parsed Queue()'s text, which caps postqueue -p at 4 MiB and
appends a note, and returned the ids before the cut with no error: the
reconcile sweep then closed every queued row past the cut as bounced while
Postfix still held the mail. listQueue() now returns the text and whether
it was cut; QueueIDs refuses a cut listing with an error (reconcile already
treats an error as no information), the way postqueueJSON does for the
notifier. Queue() keeps showing the cut listing with its note.

postqueueP is a var so tests run a fake postqueue (the test binary as a
helper process): 5 MiB -> QueueIDs errors, Queue ends with the note; 1000

mixandClaude Opus 5.5 96425dd515 e2e: a negative case passes only on its own refusal (audit stage 0)
sendResult.refusedAt(stage, code, text) and replyIs(err, code, text):
nil only for the server's reply with that code and text at that stage;
a reset, a timeout or another reply is described for the failure.

- level 1: only anvil's "450 4.7.1 Error: too much mail from", only after
  a message of the loop was accepted. Held to that, it failed twice on
  the stand, each time for a real reason:
  1. waitForSMTPSReady took a TCP connect for readiness; Docker's port
     proxy accepts before Postfix listens and then resets - the reset
     once taken for the limit. It now waits for the TLS 220 greeting.
  2. the first message then got "553 ... not owned by user l1app": an
     smtpd idle from before the panel's postfix reload took the
     connection with the old sender_login_maps. The level-1 limit had
     never been what the case saw. The first message now waits (15 s at
     most) for the map, failing at once on any other refusal.
  Now: "level-1 limit tripped on attempt 51/60: 450 4.7.1 Error: too
  much mail from 10.77.0.1".
- level 2: 451 4.7.1 at MAIL, and both MAIL FROM of one connection.
- sender mismatch: 553 at RCPT, "not owned by user".
- no AUTH and the relay case: 554 "Client host rejected: Access
  denied" at RCPT; the relay case's comment claimed
  reject_unauth_destination, which on 465 comes after the client
  restriction - port 25 holds "554 Relay access denied".
- port 25: 550 5.1.1 for unknown recipients and report addresses.
- panel down: a 4xx reply (textproto), not just text starting with 4.

The product side (a second after an application is saved when its first
message can get 553) is written in the audit plan, not changed. Audit plan
line ticked with what was found, roadmap 7/61. No CHANGELOG line: tests only.

mixandClaude Opus 5.5 86665f08e6 audit: decisions of 2026-10-13/14 on what 2.4.0 left undone
test / test (push) Canceled after 0s
Agreed with the owner, one question at a time; documents only, no code.

From from-header-binding's Not done list, each a step of the audit plan:
the Sender check column says "Connections turned away"; a stand test of
which key OpenDKIM signs with; Health connects to a milter socket instead
of stat-ing it; the cards layout orders a phone by the box's number;
a refusal the panel did not write is recovered from mail.log; a log
rotated while the panel was down is read to its end; the deferred counter
keeps a place in the log; downtime is counted when supervisord is silent.
"Today, UTC" became the roadmap item local-time (agreed): one instance
zone, no labels beside a time, days counted in that zone, with the
conditions for per-user zones and offsets, and the trap of mail.log's own
stamps written down.

The six steps on the log tailer are split off stage 1 into stage 2b, a
cut of its own (2.5.1); stages 3 and 4 move to 2.5.2 and 2.5.3.

Also: negative e2e cases pass only on their own refusal (stage 0);
notifications are owed per recipient (stage 4); a DNS outage is unknown,
not wrong (M14, M15 had no step); DMARC reports tested where they come in.
review-2026-08-followups is closed, its rows placed in stages or dropped
with a reason. Certificate warnings by lifetime: left as is, with the
condition for return.

The audit's checklist is 61 lines (was 48).

mixandClaude Opus 5.5 c3d99b1f15 roadmap: decisions of 2026-10-13 on the candidates
test / test (push) Canceled after 0s
Agreed with the owner, one question at a time; documents only, no code.

- csrf-tokens -> origin-strict (agreed): no tokens, the origin check
  refuses a request with neither header. security.md's ADR records the
  decision and when tokens are built after all.
- structured-logging, contributing: dropped, each with what brings it
  back (new roadmap section "Dropped, with the condition for return").
- template-data-typing: done by 2.0.0; its last map (healthChecks) is a
  step of the audit's stage 4.
- preflight -> health-setup-checks (certificate name, Postfix's greeting,
  trusted proxy as lines on Health) and test-email, both agreed. The port
  check is dropped with its reason; plans/preflight.md removed.
- password-reset: agreed; a reset link goes only to a confirmed e-mail,
  so the item builds confirmation first.
- phone-desktop-mode: agreed, after stages 1 and 2 of the audit.
- backup-reauth (agreed): the account password before a backup or a
  domain export, out of review-2026-08-followups.
- from-header-binding, Not done: the Delivery log box is required on a
  refused message's page, with the line Postfix wrote, for all three
  kinds of refusal (audit stage 1); the Outbound log gets a filter by
  status and by day (audit stage 4).

The audit's checklist is 48 lines (was 45).

mixandClaude Opus 5.5 8f226bd82f release: 2.4.0: an application signs only as itself
test / test (push) Canceled after 0s
from-header-binding (docs/plans/from-header-binding.md, 9/9), at the owner's
word (2026-10-12, "Да").

  - A message's From: line is held to what its envelope sender is held to:
    any address of the application's domain, or the addresses of its list,
    with or without a +extension. Anything else is refused with 550 5.7.1 -
    another registered domain, the server's own name, a domain this server
    does not sign for. Until now an application could have mail signed with
    another domain's key by writing that domain into From:.
  - The check is the panel's, first in the milter chain and strict: while
    the panel does not answer, Postfix defers mail.
  - Server > Health counts what that costs - the panel's downtime under a
    running Postfix and the submissions turned away - and is laid out anew,
    boxes numbered by importance.
  - A refused row of the Outbound log says why in its tag.
  - Migration 0006.

Upgrading: mail whose From: is not the application's own stops being
accepted - another of your domains, an address off an application's list, a
visitor's address a form puts there. The guide says what to do about each.
A stopped panel now stops submission.

Not done, written into the plan at the owner's word: the Delivery log box on
a refused message's page, the log's status filter, "messages" that are
connections, and what was reasoned about rather than run - OpenDKIM's own
parser above all.

Cut: CHANGELOG 2.4.0 written (nothing had been put under [Unreleased]
while building); image pin 2.4.0 in compose, README, guide; version table,
roadmap, plan status. security.md: a malformed packet on a milter socket,
as an accepted risk. No tag: the owner tags when he decides to, so there is
no image of this version until then.

On the test server, on c817f08: go vet ./... ok, go test ./... ok
(23 packages), make e2e ok. This commit changes documents and the pin only.

Full detail: CHANGELOG.md (2.4.0).

mixandClaude Opus 5.5 89fd0a6116 from-header-binding: findings of the technical and security reviews
test / test (push) Canceled after 0s
Both reviews were of c171fb5, read-only, given the code and questions.

Found by both, and the one that would have refused ordinary mail from the
first day: a folded From: line - what a mail library makes of a long display
name - did not parse and was refused with 550. The line is unfolded before it
is read. e2e sends one through Postfix now.

Technical (Opus)
- A display name in a charset Go does not convert (windows-1251, koi8-r) was
  refused: such a name is passed through unread, only the address is judged.
- The statistics ran between binding the socket and serving it, with a
  supervisorctl that has no timeout: they are kept beside the check now and
  nothing of them is waited for. A supervisorctl that fails is logged.
- The count of deferred mail followed smtpd's reject lines and so missed a
  check that stops answering in the middle of a message, where cleanup
  writes them: it is taken at Postfix's warning, the line that names the
  socket. The test line for that case had been invented with the wrong
  process; it is marked as composed from Postfix's source.
- A card whose figures could not be read showed zeros and "ok": dashes and
  "unknown".
- entrypoint removes the sockets a killed container left, which satisfied
  the wrapper's wait before the check was listening.
- Outside quoted strings the line may hold one "@" only - a rule that needs
  no knowledge of OpenDKIM's parser.
- Comments that still spoke of two sockets, or of a session replaced after a
  refusal; the limits of the cards layout on a phone, said where it is defined.

Security (Fable; no Critical or High)
- Another sender's name in an encoded display name passed the second look:
  the decoded name is looked at as well.
- A client could arm the deferred counter by sending the socket's name where
  Postfix quotes it in a warning: the two warnings are matched from their
  first word.
- A refused message wrote a row per recipient: one row, naming the first
  recipient and how many more.
- Docs: the check's lookup is stricter than Postfix's for address extensions
  and the case of logins, rather than "cannot disagree"; what a display name
  looks like to a person is not promised; the timeouts and the 454 at AUTH
  stated as they are; "messages" are connections turned away.

Left as found, in the plan: downtime that crosses midnight is booked on the
day of the restart; a message with the null envelope sender leaves a row
without a domain; a log read again after an unclean stop counts again.

Test server, this tree: go vet ok, go test 23 packages ok, make e2e ok (330 s).

mixandClaude Opus 5.5 c171fb5bc7 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.

mixandClaude Opus 5.5 972516d1c4 from-header-binding: agreed, taken into work
The design questions were closed with the owner on 2026-10-12, one at a
time; the plan records what he chose and what I had proposed instead.

- The rule: From: is held to what the envelope is held to - any address of
  the application's domain, or the addresses of its list. Anything else is
  refused, a domain this server knows nothing of included (I had proposed
  to refuse only names the server signs for).
- The check is the panel's and strict: while the panel does not answer,
  Postfix defers mail. It gets a socket of its own so that the journal
  stays fail-open, and reads Postfix's own file of sender bindings.
- Server > Health counts the panel's downtime under a running Postfix and
  the mail deferred for it, to decide later whether the check needs a
  process of its own.
- A refusal is 550 5.7.1, and its reason is the row's status tag.

mixandClaude Opus 5.5 ce7b09a65c release: 2.3.0: the panel writes to its users
test / test (push) Canceled after 0s
panel-notifications (docs/plans/panel-notifications.md, 10/10), at the
owner's word (2026-10-12, "Да").

  - Four things are reported by e-mail, each once: a sending domain's
    DNS record that does not match, a level-2 rate limit refusing mail,
    the TLS certificate about to expire, a message more than three days
    in the queue. Global users are told all of it, domain users about
    their own domains.
  - Sent from postmaster@<SELFPOST_HOSTNAME> and signed with a DKIM key
    of the server's own name, which the panel generates.
  - Account has the user's switch, Server > Settings the instance's and
    the two DNS records to publish, Server > Health their state.
  - An account e-mail may now be at a public mail host.
  - Migrations 0004 and 0005.

Upgrading: publish the two records Server > Settings shows for the
hostname (a DKIM key and "v=spf1 a -all"); until then notifications are
sent and may be filed as spam. Every user with an e-mail starts with
notifications on. non_smtpd_milters now names OpenDKIM.

Accepted and recorded in security.md: an application can have a message
signed as the server's own name by writing it into From: (roadmap
candidate from-header-binding).

Cut: CHANGELOG [Unreleased] -> [2.3.0]; image pin 2.3.0 in compose,
README, guide; version table, roadmap, plan status. No tag: the owner
tags when he decides to (2026-10-11), so there is no image of this

mixandClaude Opus 5.5 f09b60aaa2 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).

mixandClaude Opus 5.5 b905f3e560 panel-notifications: Account, Server > Settings, Server > Health, help; e2e
test / test (push) Canceled after 0s
The pages of the mockups accepted in 87fa0a4, built from the kit's partials
(written by a Sonnet agent into the working tree, reviewed here):

- Account: "Send me notifications" in the Profile form, saved with the
  profile; an unticked box is off.
- Server > Settings: the instance switch (box 03), and box 04 Notification
  mail with the DKIM and SPF records of the server's own name, drawn with the
  record partial of a domain's DNS page and checked in DNS. Sending rate
  limits are box 02 in the left column. A record that is not in place is
  tagged as a warning, not a failure: notifications are sent without it.
- Server > Health: card 06 Notification mail with the state of each record
  and a link to Settings, beside Configuration (07); part of the polled
  fragment; Re-check DNS forces it too. Overview does not run this check.
- help.go: the Notifications topic and the clauses in Settings and Your
  account, word for word with help.html.

If the server's key cannot be read the pages still render: the DKIM record
is left out and SPF is shown unchecked.

e2e: the administrator gets a mailbox behind the sink and the server's DKIM
record from Settings is published; the level-2 refusal of the next step must
then arrive as a notification from postmaster@mail.e2e.test, signed as that
name with the key Settings shows, and must not be a row of the Outbound log.
The rotation step now waits for Postfix to be running: it follows a step that
restarts the container, and logrotate's `postfix reload` failed in between.

On the test server, for this tree: go vet clean, go test ./... 23 packages
ok, make e2e ok (147 s); the notification reached the sink 28 s after the
refusal.

mixandClaude Opus 5.5 c9027381e5 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.

mixandClaude Opus 5.5 50fd6b859f 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.

  Notification mail with the two DNS records of the server's own name, DKIM
  and SPF, drawn with the record component of a domain's DNS page. Sending
  rate limits move to the left column as box 02.

- help: a Notifications topic (what is sent, when, to whom, what makes it
  arrive); Settings and Your account each gain a clause.
