mixandClaude Opus 5.5 9efc9c7005 release: 2.4.2: audit stage 0, release hygiene
test / test (push) Canceled after 0s
Stage 0 of docs/audit-2026-10-12.md, 7/7: the release image says which
release it is (H1), the e2e module is compiled on every push (M20),
test/ is out of the build context (L33), the documents say the 2.x image
is not published and show the local build (M6), dependencies raised,
staticcheck clean, the negative e2e cases held to their own refusals
(which showed the level-1 rate-limit case had never seen the limit).

CHANGELOG cut; pin 2.4.2 in deploy/docker-compose.yml, README (with the
local-build note), guide; development.md "from pin" and the planned cuts
of the audit's stages (2.5.0 ... 2.6.0); roadmap row in progress and the
recommended order; stage 0 marked shipped in the plan. No tag (the
owner's command only).

mixandClaude Opus 5.5 937b41ddb7 docs: say the 2.x image is not published; show the local build (audit M6)
README, guide and deploy/docker-compose.yml pinned
ghcr.io/mixeme/selfpost:2.4.1, which does not exist: ghcr.io holds 1.0.0
and 1.3.0 only. The owner decided (2026-10-12) that old tags and images
stay untouched and the pin points forward, made true by the next
publication. Until then:

- README Quick start and guide Fixed image tag say the 2.x line is not on
  ghcr.io and show `docker build ... --build-arg VERSION=2.4.1 -t
  ghcr.io/mixeme/selfpost:2.4.1 .`; with the image present locally,
  docker run and Compose (pull_policy missing) use it without pulling.
- compose header says the same in two lines.
- development.md release steps: bump the version in those notes at each
  cut, remove them at the first publication of the line.
- CHANGELOG [Unreleased], audit plan line ticked, roadmap 4/61.

Documents only; no test reads the pin.

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 c817f0833c 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).

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 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
version until then.

On the test server, on f09b60a: go vet ./... ok, go test ./... ok
(23 packages), make e2e ok.

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 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.

test / test (push) Canceled after 0s
delivery-log-storage (docs/plans/delivery-log-storage.md, 8/8), at the
owner's word (2026-10-12, "Да").

  - The log tailer stores what Postfix writes about queued outbound
    messages; a message's page reads it from the database, so the
    Delivery log box no longer empties when mail.log rotates. The lines
    live as long as the send-log row and go with it.
  - Mail that came in on port 25 is not stored.
  - Migration 0003 (send_log_lines), DDL only.

What an operator should know: the stored lines are 1-2 KB a message
and are in a full backup, which mail.log is not (security.md). A
message accepted before this version shows its lines only while they
are in the current file.

Cut: CHANGELOG [Unreleased] -> [2.2.0]; image pin 2.2.0 in compose,
README, guide; version table, roadmap, plan status. No tag: the owner

inbound-antispam-panel (docs/plans/inbound-antispam-panel.md, 12/12),
at the owner's word (2026-10-12, "Да").

  - Inbound mail is recorded: accepted mail by a second, read-only
    milter on port 25 with the spam filter's verdict, refused mail from
    the mail log. The filter signs what it judged, and a verdict is
    shown only next to its signature.
  - Inbound > Log, with a sheet over the page that says who decided
    and why; Inbound > Filter lists, allow and deny entries written as
    rspamd maps, each with how often it decided a message.
  - Migration 0002 - the first after the 2.0 baseline.

Security, outside the feature and in every release since 1.9.0: the
level-2 rate limit and an application's client IP list held only for
the first message of a connection. Fixed; e2e sends two MAIL FROM on
one connection.

Upgrading an installation with the antispam sidecar: copy
deploy/antispam/ again (the fragment mounts two new things) and
restart the sidecar. Port 25 now logs as postfix/inbound.

mixandClaude Opus 5.5 1f44e40382 inbound-antispam-panel: the filter reads its signing key for every message
test / test (push) Canceled after 0s
The routine kept the key after its first read. SelfPost makes a new key
when the file is lost or damaged, or a backup brings back another, and
rspamd would then have gone on signing with the old one - every verdict
unrecorded - until someone restarted the sidecar. The file is one short
line; reading it per message costs nothing worth keeping a copy for.

The guide says what never needs doing: nothing of rspamd's is cleared
after a change of the lists or the key; a restart is for a change of
its own configuration only.

Prompted by the owner's question whether rspamd's cache needs clearing
(2026-10-12).

mixandClaude Opus 5.5 d398f488e2 inbound-antispam-panel: the filter signs what it judged
test / test (push) Canceled after 0s
Closes what the security review left as an accepted risk: with the
spam filter down - it is attached fail-open - nothing removes verdict
headers a sender wrote himself, and the inbound journal recorded his
verdict as the filter's. The owner asked whether rspamd could add a
header that proves the others are ours (2026-10-12) and agreed to a
signature: a fixed mark could be written by a sender as easily as the
verdict.

  - inbound.FilterKey: a key of 32 random bytes, 64 hex characters, in
    /data/antispam/filter.key, made on the first start with the relay
    on. 0644 like the list files beside it: the filter is another user
    in another container.
  - deploy/antispam/rspamd/milter_headers.conf: a custom routine reads
    the key through the directory the sidecar already mounts and adds
    X-SelfPost-Filter, the HMAC-SHA256 of the message's queue id, hex;
    a header of that name from the sender is removed.
  - internal/milter/inbound.go: the verdict headers are kept as they
    are read, and at end-of-message - when the queue id is known - they
    count only if the signature fits (FilterSignature, hmac.Equal). No
    key, no queue id, no signature or a wrong one: the row is that of
    mail nobody judged (accept, selfpost, no detail).

The signature goes on to the upstream with the mail and is of no use
there: it fits one queue id.

Tried in a throwaway rspamd 3.11 container on the test server before
the Go side was written: the routine loads, signs
(2aa1ca6d... for key 0123...cdef and queue id 4A1B2C3D5E, the value
python's hmac gives and TestFilterSignatureIsWhatTheFilterWrites
pins), removes a sender's header of the same name, and adds nothing
without a queue id.

Tests: signed, unsigned, made-up, another message's, another key's,
the sender's followed by the real one, the next message on the
connection, no queue id; the key made once, read after, replaced when
damaged, left alone by the lists. e2e: filter.key is there, 644, 65
bytes.

docs/security.md: the accepted risk is replaced by a narrower one (the
key is readable on the host); Mail path describes the signature.

Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

mixandClaude Opus 5.5 c731a98a0f inbound-antispam-panel: findings of the technical and security reviews
test / test (push) Canceled after 0s
Steps 11 and 12 of docs/plans/inbound-antispam-panel.md: 12/12. Two
read-only reviews of d65d632..HEAD by different models (Opus,
technical; Fable, security), each given the code and questions, not
conclusions. Nothing Critical or High in the feature; the High the
technical review found outside it is the commit before this one.

Log tailer (internal/logtail/inbound.go):
  - the reply of a refusal ends at the first "; from=<", Postfix's own,
    and the HELO name after it is whatever is left. Taking the longest
    reply let a HELO name that spelt "; from=<..> to=<..> proto=.."
    supply the row's sender, recipient and reply - and so make a
    refusal read as the deny list's;
  - an address with a quote, a bracket or a space is not kept: a quoted
    sender could otherwise supply the recipient;
  - the journal is cut to its row cap every 500 rows written, not only
    every six hours;
  - a queue id is forgotten when the message is queued or the id is
    opened by another listener, and a stale place in the queue of
    arrivals no longer drops a live id;
  - milter-hold lines are not read: the held message reaches the
    journal milter, which writes its row - it was written twice.
Lists (internal/inbound/lists.go): a change of the table and the
rewrite of the files are one step under a mutex; a failed rewrite puts
a removed entry back and rewrites after taking a new one out.
Store: the row cap removes the oldest by time, as the page orders them.
Page: on a sheet a refusal's text is a Reply whatever it starts with.

Help and the guide say that an allow entry for a sender address trusts
an address anyone can claim (design commit before this one).

docs/security.md: the two reviews; the roles table gains Inbound > Log
and Filter lists; Mail path describes the milters, the tailer and the
lists; four accepted risks - the filter's verdict while it is down, an
allow entry by sender address, the list files' mode, log rows held by
domain name. The plan's stale lines (size and rate refusals, who reads
the journal) are corrected.

Left as found, told to the owner: the journal's rows after an unclean
stop may be written twice (the tailer saves its place every five
seconds); a "Deny sender" link is offered for an address the form then
refuses; 1.2.3.4 and 1.2.3.4/32 are two entries.

mixandClaude Opus 5.5 7192c3861e inbound-antispam-panel: Filter lists, kind column, matches, note on a sheet
Follows the design commit before it (owner's words quoted there).

The lists' tables are Value, Kind, Matched and Remove. The kind tag
opens the entry's sheet: note, day added, how often it decided a
message in the days the log keeps, and the last match.

Matches are read off the journal on each view, nothing is stored
(inbound.Lists.Usage, store.ListSpamListHits). A row counts for an
entry when the list decided the message - a rejected row whose reply is
the deny rule's message, an accepted row whose verdict carries the
allow rule's symbol for that kind - and the entry fits the row's sender
or client address the way rspamd matches it: an address whole, a domain
as the sender's domain, a network containing the client (an
IPv4-mapped address as IPv4). A failure to count shows the lists with
"never" and logs why.

For that the journal milter keeps the lists' own symbols ahead of its
six-symbol cap: rspamd writes symbols heaviest first, so an allow
entry's -100 came last and was cut behind any six others.

The plan gains "Filter list usage": what counting from the journal
implies, and - the owner asked for it in writing - the conditions under
which a counter kept with each entry becomes worth a migration (the
journal cut by its row cap and not by age; a short retention; counts
that must outlive the journal; a slow page). multimap.conf says which
of its texts SelfPost reads back.

Tests: Usage over every kind on both lists and the rows that are
nobody's; the milter's symbol order; the store query; the page and its
sheets; a handler test from journal rows to the numbers on the page.

Seen: the fixture page with a sheet open, headless Edge at 1360 px -
the same as the accepted drawing.

Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.

Not seen in a real run: a count above zero. It needs an entry added in
the panel, which I cannot sign in to, and then mail that the list
decides; in particular the deny rule's message arriving in mail.log as
the reply of a milter-reject line is what the trial with rspamc showed,
not yet what Postfix logged.

mixandClaude Opus 5.5 c1da784193 inbound-antispam-panel: the backup holds the lists; Inbound log accepted
Step 7/12 of docs/plans/inbound-antispam-panel.md. A full backup walks
all of /data, so data/antispam/ was in it from the day the directory
existed; TestCreateIncludesStateExcludesTransient now holds that. On
the first start after a restore the maps are written again from the
database (mailStack.Resync, already there). The guide says what is not
in a backup: the antispam/ directory with the compose fragment and the
rspamd configuration, which is installation and not state.

The plan records the owner's acceptance of Inbound > Log (2026-10-12,
"Этот экран утверждаем") and what he changed on the way to it.

mixandClaude Opus 5.5 56c5dfee40 inbound-antispam-panel: Inbound > Log and Inbound > Filter lists
Step 6/12 of docs/plans/inbound-antispam-panel.md. Written by a Sonnet
subagent from the mockups, reviewed and corrected by me.

GET /inbound/log - the journal a page at a time (50), filtered by
domain, decision and day; QueryInboundSpam / CountInboundSpam with the
viewer's inbound domains as the scope. The global role reads all of it
and gets "Deny sender" / "Allow sender" links into the lists; a user
with the domain role reads the rows of the inbound domains assigned to
them, without the links. The plan said global-only for the journal;
the accepted mockup and 2.0's delegation of Inbound say otherwise -
recorded in the plan as built.

GET, POST /inbound/filter-lists and POST .../{id}/delete - global role,
404 otherwise. Add form (prefilled from the query), the two lists with
Remove as the kit's row action, and "Where the lists go" with the
filter's state and when the maps were last written
(Lists.LastWritten). A refused or duplicate entry is 422 with the
message and what was typed.

Server > Settings: "Keep inbound log rows, days" with the relay on.
Help: Inbound log, Filter lists. Navigation: Log for everyone who sees
Inbound, Filter lists for the global role (Shell.ShowFilterLists).
Status tags accept / reject / tempfail join the kit's mapping.

Tests: page fixtures for both screens, held to outlines.json; view and
handler tests (both roles, filters, paging, relay off, add / duplicate
/ invalid / delete, map file content, settings field, help). e2e reads
the journal from the page instead of the database and adds and removes
a deny entry through the panel, reading deny_domain.map after each.

Seen: both pages and Settings rendered from their fixtures and compared
with the mockups side by side (headless Edge, 1360 px) - same layout
and wording.

mixandClaude Opus 5.5 eea40bcd49 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.

mixandClaude Opus 5.5 27fd355e53 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.

mixandClaude Opus 5.5 28ec784ae2 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.

mixandClaude Opus 5.5 dd0fefdcb7 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.

mixandClaude Opus 5.5 21e961cb29 backup: no full backup holds the Postfix queue
Owner, 2026-10-11: the queue goes out of the command's archive too.

The commit that made the panel's backup work left the queue in the
archive of selfpost-backup, which runs as root and can read it. But that
copy was never the queue: the archive is made while the instance runs,
Postfix moves messages between the queue's directories all the time, and
a message on its way could be in the archive twice or not at all. One
rule now - QueueDir is left out of every archive - and
Params.Unprivileged is only about a certs/ file the panel may not open.

What is not carried over is mail still waiting for delivery; a restored
instance builds an empty queue (the e2e restore scenario starts one).
To keep the queue: stop the instance and tar the project directory, as
the guide's methods 3 and 4 already describe.

Guide: the description of a full backup, methods 1 and 2 and the
comparison table. Help follows the design commit before this one.

mixandClaude Opus 5.5 8c9a71e6a0 backup: the panel's full backup works, without the queue
Found by the e2e restore scenario of the next commit: the Full backup
button answered 200 with ten bytes. The archive includes the Postfix
queue, Postfix keeps every queue file and directory readable by its own
user alone (not configurable), and the panel runs as its own user - the
walk stopped at /data/postfix/queue/active with "permission denied"
after the headers were out. So since the queue moved under /data in
1.3.0. Confirmed on the test server: selfpost-backup as root makes the
whole archive, the same command as user panel fails the same way.

Owner, 2026-10-11: the panel's archive comes without the queue.

- backup.Params.Unprivileged: the queue is left out, and so is a file
  under certs/ that cannot be opened (the private key on the test
  server is root and Postfix's group only), named through OnWarn. The
  selfpost-backup command leaves it unset and takes both, as before.
- backup.Check reads through everything Create would archive, writing
  nothing. The panel runs it before the first byte: a failure is a
  message on the page, not a download cut short.
- The box, Help (design commit before this one) and the guide say what
  the panel's archive leaves out; the guide's comparison table has rows
  for the queue and the private key, and tells to put the key back
  before starting a restored instance.

mixandClaude Opus 5.5 4dd46ea355 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.

stranger can and cannot do now. The roadmap no longer calls the review
pending.

Owner, 2026-10-11: foreign and malformed reports are turned away.

The command answered every failure with EX_TEMPFAIL, so Postfix kept a
message that could never be stored and offered it again for days, each
attempt adding to the parse-failure count. IngestMessage now marks those
failures (unreadable as an aggregate report, a domain not sent from
here, another domain's report address) with ErrRejected; the command
counts one failure, writes the reason where Postfix puts it on the delivery line of the mail log
and reports the delivery as done. No bounce: the envelope sender of such
a message is whatever its author wrote, and the report addresses are
public. A failing store is still EX_TEMPFAIL.

Stage 3, step 3. Written by Sonnet from the code and the plan, checked

  - guide.md: a section on the panel - menu, paths, the roles global and
    domain with outbound and inbound assigned separately -, Overview and
    Health, Queue and System log, Account and Server > Settings, the
    domain page / Domain settings / application form, Help as a page of
    topics. The DMARC report address is one of three choices set in
    Domain settings. The Spam filter box, the two INBOUND_ANTISPAM_*
    variables the panel reads, and the filter's socket on Health.
    Sessions; backup and export encrypted unless the box is unticked;
    1.x data is not restored into 2.0.
  - architecture.md: Panel HTTP surface rewritten from web.go (routes,
    the /server/ guard, per-object checks, <page>/fragment, one layout,
    typed page data, the kit and its guards, CSP and htmx); Persistence
    gains the database - one baseline, a 1.x file refused, the tables as
    they are.
  - security.md: roles and what each reaches, as built; sessions by user
    id and what ends them; state-changing requests; errors shown to
    users; the 2.0 review; two accepted risks from it - a delegated
    inbound upstream may be any host and port, and Account's profile is
    saved without the password.
  - CHANGELOG: Removed opens with "2.0 starts from an empty data
    directory"; entries that describe the user-default report address
    say they were replaced before release; the filter's socket.
  - roadmap.md: two review follow-up rows struck as retired by the
    redesign (.pair / .split, the two back links); password-reset notes
    that changing the account e-mail must then ask for the password.
    Progress 25/27.
  - development.md: the component kit and its guards; README and
    product.md: wording.

Left as they are
  - The third follow-up row the plan expected to strike - initShowWhen
    is not re-run after an htmx swap - still holds: no polled fragment
    carries such a control today, so nothing breaks, but the redesign did
    not retire it.
  - guide.md embeds no screenshots, so none needed retaking.
  - README and guide still name image 1.9.5 - the version cut.
  - plans/preflight.md and plans/inbound-antispam-panel.md use pre-2.0
    paths; roadmap's template-data-typing is largely done by the
    redesign.

mixandClaude Fable 5.1 1e92c5b2a2 release: 1.9.4: Panel-redesign plan: component kit, stages, reorder (docs only)
Plan-only cut, owner-requested. The redesign goes first as 2.0.0 and
inbound-antispam-panel follows as 2.1.0 on the 2.0 baseline (migration
0002_inbound_spam_log.sql), built from the redesign's component kit so its
two screens are styled once. No product code changes.

Changed:
  - panel-redesign plan: Component kit section and stage 0 (partials with
    typed inputs in components.go, one panel.css, /server/components kit
    page, acceptance before any page is restyled); staged checklist (5/27);
    Health decided inside 2.0, queue pages left as old content in the new
    shell.
  - panel-redesign plan: Against resurrected pages - shrink-only
    legacyPages ratchet in the guard tests enforced by CI, the outline
    golden, the old-path test and a history-blob check, so an old template
    from git history cannot pass as a redesigned page.
  - roadmap: new candidate delivery-log-storage - the Delivery log box on a
    message page is empty for anything older than the last daily rotation
    because the lines are grepped from the current mail.log on each view
    and never stored.
  - development.md version table, image pin 1.9.4 in compose, README, guide.

mix 6bfaa518d7 release: 1.9.3: Panel-redesign prep: mockups, routes, design contract (docs only)
test / test (push) Canceled after 0s
Panel-redesign prep, docs only: stage 1-2 mockups on all 33 screens, the accepted header/type-scale/contrast corrections, the account e-mail and inbound-delegation decisions, and the routes/quarantine/preflight roadmap screens. Nothing in `internal/web` changes; the design stays `candidate` (3/21) until the redesign itself ships as `2.0.0`.
Added:
  - Panel redesign, account e-mail and notifications: a user's e-mail is its own
  - Panel redesign, contrast: a sweep of every text node against its real ground
  - Panel redesign, header (owner's choice: variant A, with the perforation on a

mix 7ef7f75246 release: 1.9.2: Review pass: port-25 milters, DMARC validation, rate-limit fix
Review pass over `1.4.0`…`1.9.1`: port 25 no longer shares the submission milter chain, DMARC reports are validated before they are stored, and the auto rate limit is correct for a non-default level-1 window. Schema migration `0010` (index only). Upgrading is a tag bump.
Added:
  - SQLite migration `0010_send_log_app_login_index.sql` —
  - DMARC aggregate reports are accepted as **zip** as well as gzip or plain XML
  - e2e: `checkPort25ConfigCombinations` regenerates the Postfix configuration

mix 7b8685d038 release: 1.9.0: Per-application client IP allow-list and rate-limit overrides
Application sending controls: client IP allow-list for authorization, and level-2 rate limits that override the domain ceiling per application.
Added:
  - Per-application **client IP allow-list** on the domain page: when enabled,
  - SQLite migration `0009_application_auth_ips.sql` (moves legacy trusted IPs
Changed:
  - Application level-2 rate limit **overrides** the domain limit for that login
  - Domain export/import carries `auth_ip_restrict` / `auth_allowed_ips`; legacy
  - Panel help, Settings, and [guide.md](docs/guide.md) describe override semantics

Built-in operator documentation in the panel: a CSS-only help drawer and Help page so Status checks and domain controls are explained without leaving the panel.
Added:
  - **Help** navigation entry and `/help` index page.
  - CSS-checkbox help drawer (no extra script): seeded topics for Status (Machine,
  - «?» entry points on Status and domain card heads open the matching drawer

Added:
  - Domain page **Sending statistics** card: total messages, peak and average
  - Level-2 rate limit **Manual** / **Auto** mode on domain and application

mix 656c4d4d7f 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.

mix 0730b2090e release: 1.3.0: 1.3.0-1.3.1: security pass, queue persist, full backup layout
[1.3.0]
Security and quality after 1.2.5: domain-admin send-log authorization, fail-closed sign-in and application delete, level-2 rate-limit race fix, restore Resync, expanded tests, operator docs, release CI, and OFL for IBM Plex. Upgrading from 1.2.x is a tag bump; no migration.
Added:
  - licence: the SIL Open Font License 1.1 text now travels with the IBM Plex
  - docs: agreed roadmap item **queue-retries** — show this Postfix's retry
Security:
  - The independent security review of the send-log authorization and
Fixed:

[1.3.1]
Retry policy in the panel, persistent Postfix queue, and self-contained full backups. Mail queue and delivery history show this Postfix's first retry, backoff cap, and queue lifetime. Deferred mail survives container recreate. Full backups now archive `data/`, compose, `.env`, and `certs/`; the archive layout breaks 1.3.0 flat backups (unpack those with `tar xzf backup.tar.gz -C ./data` as before). Upgrading from 1.3.0 is a tag bump; no schema migration.
Added:
  - Mail queue and a delivery's history show this Postfix's retry policy
  - docs: **Plan checklists** in [development.md](docs/development.md) — format,
  - docs: **Implementation checklists** with model routing in
  - docs: roadmap candidates **send-log-retention** (panel Settings for delivery

[1.2.0]
The second MINOR after 1.0.0: domain administrators with per-domain scope, a panel visual refresh on the SelfPost palette, and refinements to navigation and the send log. Upgrading runs one SQLite migration (`0005_panel_users`); the single administrator becomes a global user.
Added:
  - panel: **domain-admin role** — global administrators manage panel users and
Fixed:
  - Docker build: `LICENSE` is no longer excluded by `.dockerignore`, so the
  - panel: on signed-in pages with a narrow card (**Settings**, the user form)
Changed:
  - panel: navigation session icons are distinct — **Settings** uses a gear,
  - panel: `/` redirects domain administrators to `/domains`; global users still
  - panel: **Sign out** in the navigation column uses the same type size and
  - panel: **visual style** brought in line with the SelfPost mark — brick accent
  - panel: the send log's **status is a badge**, in the same ok/warn/error/unknown

[1.2.1]
Panel refinements after 1.2.0: navigation icons, status-badge centreing, drill-down back-link placement, and safeguards for the sole global administrator. Upgrading is a tag bump; no migration.
Fixed:
  - panel: status badge text sat low in the box (and below the heading or label
  - panel: the **Users** navigation icon was two full silhouettes with staggered
  - panel: the **Settings** navigation icon was a sun-with-rays (circle plus
  - panel: the user create/edit form placed «Back to users» at the bottom of the

  - panel: the user edit form disables role change and delete for the only global
  - panel: the user create/edit form hides **Assigned domains** when the role is
  - panel: **Settings** shows panel credentials and DMARC aggregate reports side
[1.2.2]
Status page layout after 1.2.1: paired cards in a wide column, denser machine and check copy, and a user-form checkbox fix. Upgrading is a tag bump; no migration.
Changed:
  - panel: **Status** is wide again so paired cards fill the column. Layout:
Fixed:
  - panel: cards inside `.split` used `margin: 0 auto`, which in a CSS grid
  - panel: on the user create/edit form, **Assigned domains** checkboxes stacked
[1.2.3]
Domain detail layout and panel polish after 1.2.2. Upgrading is a tag bump; no migration.
Changed:
  - panel: the domain detail page is wide with paired cards (DKIM+SPF ‖ DMARC;

[1.2.4]
Level-2 rate-limit semantics inverted after 1.2.3, plus a small DNS field height fix. Upgrading is a tag bump; no migration.

Fixed:
  - panel: on the domain DNS status grid, the Type (TXT) field height matches

Rate-limit form polish after 1.2.4. Upgrading is a tag bump; no migration.

mix f62fe23826 release: 1.1.0: Domain-admin role and internal/web package split
The first MINOR after 1.0.0: send-only DMARC guidance in the panel, AGPL packaging on every page, and an internal split of `internal/web` ahead of domain-admin work. Upgrading runs one SQLite migration (empty defaults; existing DNS guidance is unchanged until you set a report address).
Changed:
  - `internal/web` split into subpackages (`web/view`, `web/auth`, `web/validate`,
Added:
  - panel: DMARC guidance for send-only relays — the suggested `_dmarc` record
