The owner's phone, 2026-10-17: "Маленький зазор над полем почты"; design
the commit before this one. panel.css takes the two rules theme.css gained
(TestPanelCSSIsTheMockupStylesheet holds them equal): a tag in a field's
label or a fact's dt has no padding of its own and line-height 1.5, so the
line keeps the label's height. CHANGELOG [Unreleased] § Fixed.

The owner's phone, 2026-10-17: "Маленький зазор над полем почты" - on
Account the e-mail's "not confirmed" tag made its label's line taller
(Bulma's tag is 2em high, 26 px against the label's 21), leaving less room
under it than under Username. A tag beside a label's text - a field's
label or a fact's - now takes the text's line height; measured on the
mockup at 412 px, both labels leave the same room above their field.

проблема. Пояснения добавь. Все мелочи закрой." Designs 9b33b80, 2bf9056.
DMARC: a report's day stays the reporter's, in UTC (RFC 7489 § 7.2); the
report's Window now says so under its times (windowNote), and Settings'
Time zone box and Help (#settings, #dmarc) name it as the one exception to
the panel's zone. formatDMARCWindow counts a window that ends at midnight
as ending the day before, so a daily report is one day, not "20 Sep - 21
Sep" (TestDMARCWindowIsTheReportersDay, in Moscow's zone).
Health: with the inbound relay on, the inbound journal milter's socket is
dialled (InboundJournalSocket through web and handlers Config), fail-open
as the send log's, and Overview's card counts it; the send log's socket is
named journal-milter, as the mockup names it.
The confirmation link's sign-in state is drawn (confirm-email-signin.html);
the panel already renders it.
guide: /license and /server/components, the DMARC pages' paths and day,
selfpost-backup -o / -i / -version, the Inbound log's retention field,

The owner's "Все мелочи закрой" (2026-10-17), from the docs audit: the
inbound journal milter (Inbound › Log, port 25, fail-open) was the one
milter of the panel Health did not dial. Its row joins Milter sockets with
the inbound relay on, and Overview's card counts it (6 of 6 answering).

A DMARC report's day stays the reporter's, in UTC - the title and the lists
name it - and the panel now says so: the report's Window shows its
boundaries in this panel's zone with a line under them naming the
reporter's day; Settings' Time zone box and Help (#settings, #dmarc) name
it as the one exception to "every time is this zone's".

The owner's "1" (2026-10-17), the two shown side by side; design 9aebe1e.
overviewHead writes "Mail is flowing. Nothing needs attention." when every
card is fine, "Mail is flowing. One thing needs attention." (or "N things
need") for warnings, and "Mail may not be flowing. ..." when a card fails;
the lead names each card that is not fine, linked, with its value inside
the sentence ("TLS certificate: expires in 12 days."), separated by
semicolons. lowerFirst lowers a value's first letter unless it is an
abbreviation ("CPU 98 %"); every value the cards write is a phrase.
Tests: TestOverviewHeadSentences (the three states, two cards, an
abbreviation), the Overview page and fragment, TestFilterDownIsAMissingSocket.

The owner's "1" (2026-10-17), shown both: Overview's head says what the
mockup says - "Mail is flowing. One thing needs attention." - and is made
from the cards as the panel's is. Its lead is what the panel can write: each
card that is not fine, linked, with its value ("TLS certificate: expires in
12 days."), instead of a sentence the cards do not hold ("has not renewed
yet").
The states the panel writes from it: all fine, "Mail is flowing. Nothing
needs attention."; a warning, "Mail is flowing. One thing needs attention."
(or "N things need"); a failure, "Mail may not be flowing. One thing needs
attention." - a failed card is Postfix, a socket, a queue that cannot be
read, which can stop mail.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Agreed by the owner on 2026-10-13 ("the e-mail must be confirmed");
notifications to an unconfirmed address settled on 2026-10-17: "Без
подтверждения слать". Mockups 2f5f5b2, route guard b7bbb2c, panel guard
0774da2.
Migration 0013: users.email_confirmed_at ('' for every address saved
before it) and user_links - the SHA-256 of a link's token, its user,
purpose (confirm, reset), address, created and expiry. A changed address
loses its mark (keepConfirmed, in UpdateUser and SaveUser).
internal/web/auth/links.go. A link is 256 bits from crypto/rand, mailed as
https://SELFPOST_HOSTNAME/... - never the request's Host. Confirmation:
24 h, sent when an address is saved (Account, or the global role's user
form) and by Account's Send the link again; its page /confirm/<token> has
a button (a GET changes nothing) and confirms only for a session of its
own account. Reset: /login/reset asks for a username and answers the same
for every name (the sign-in page, "If that account has a confirmed e-mail,
the link is on its way"), mailing after the answer; only a confirmed
address gets one, none within ten minutes of the last, five links an hour
per account, five requests in 15 minutes per client address;
/login/reset/<token> (30 min) sets the password with the link taken in
the same transaction that checks the address again
(store.TakeResetLink), then ends every session. Changing the e-mail on
Account asks for the current password. A password set on Account or the
user form removes the reset links; a restore removes every link; the stop
waits for links being mailed (Server.Drain); a rejected request's log line
hides a link's token (loggedPath).
Reviewed for security before the commit (2026-10-17): no high; two
medium and five low, all fixed here - confirming needs the account's
session and the mail does not name the account (a mistyped address was a
takeover); a reset request neither replaces the links already sent nor
spends the account's quota inside ten minutes; take-and-set atomic; the
confirmation mail sent after the answer; the stop waits for mail; a
restore deletes the links; the token kept out of the log.

password-reset (owner, 2026-10-13: "the e-mail must be confirmed";
2026-10-17: "Без подтверждения слать"); mockups 2f5f5b2. login-reset,
login-reset-set and confirm-email are drawn as sign-in and setup are, the
form column of the signed-out screen with no shell to outline: they join
those two in noOutline, and the structure check's signed-out case reads
one list of them (signedOut) instead of naming two pages. Every other rule
holds them.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
password-reset, agreed 2026-10-13 ("the e-mail must be confirmed") and
settled 2026-10-17 ("Без подтверждения слать": notifications go to an
unconfirmed address, a reset link only to a confirmed one); mockups
2f5f5b2.
Public, as /setup/ is: /login/reset (the form that asks for a link),
/login/reset/<token> (the new password from the link), /confirm/<token>
(the address confirmed from its link) - each link is opened from a mail,
signed in or not. Behind a session: POST /account/email/confirm, Send the
link again on Account.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Agreed 2026-10-13 ("the e-mail must be confirmed"); his choice of
2026-10-17 for notifications: "Без подтверждения слать" - they go to the
address confirmed or not; only a reset link needs it confirmed.
Sign-in gets "Forgot your password?" (login.html). login-reset.html asks
for the username and says what will happen; login-reset-sent.html is the
sign-in page after it, the same answer for any name ("If that account has
a confirmed e-mail, the link is on its way"); login-reset-set.html sets
the new password from the link and says that every session ends.
confirm-email.html is where the confirmation link lands: a button, not a
GET that changes state, as a mail scanner opens links.
Account: the e-mail's tag (confirmed / not confirmed), what a new address
is sent, the current password asked only to change the e-mail (roadmap,
2.0 security review: the e-mail becomes where a reset link goes), and
"Send the link again" while it is unconfirmed. The user form shows the
tag too. Help #account says it all. The user form loses "The same form,
empty, creates a new user" (panel-words: a new user has its own head).

The owner's "проверь, что документация актуальна с кодом" (2026-10-16);
design c5edbd8 and f1cc3f3 settled which side moves.
The panel follows its mockups: an inbound domain's MX box ends with
"Checked N ago" (dnscheck.InboundMXCheckedAt, from the cache) and its side
menu has See also › Log for this domain (the Inbound log, filtered); a
deferred message's history ends with the open dot of the wait in the
queue, the lifetime from this Postfix; Health's lead says six cards;
Overview's head says it refreshes on its own; DMARC's hint for an
unaligned third party is the mockup's sentence.
Help, word for word with the mockup and true to the code: the
application's password kept by the server (sasldb2) for an export, a
From:/Sender: refusal one row of the Outbound log, every backup password
check counted (AllowPasswordChange before the compare), a password set
for another user ends all their sessions, the limit mail daily per
sending domain. The Filter lists topic and its menu entry are no longer
shown to a domain administrator: their page is 404 to one
(requireInboundGlobal), and Help shows only what its viewer can open.
guide.md: Health's readings in the order of the boxes, with Notification
mail; the menu and role tables have the Inbound log and Filter lists; port
25's chain has the inbound journal; level 2 does not depend on the client
address, the client list refuses a message without one; four kinds of
refusal (wrong Sender); the log is filtered, not searched, and a message
is traced by its row; a bounced row shows only the queue lifetime;
TRUSTED_PROXY_CIDR serves sign-in and setup, the account-change limit is
per user; notifications' first check and hourly ceiling. The Apache
vhost's comment names mod_rewrite.
Tests: TestHelpHasTheInboundLogAndFilterListsTopics (the topic per
viewer), TestDeliveryPageDeferredUsesRetryPolicy (the wait),
TestInDomainShowsTheMockupsBoxes (checked, the log link), the Overview
head; the DMARC tests take the new hint. go vet + go test (26 packages)

Following c5edbd8, two lines where the panel had already decided on
purpose, with tests that hold it (server_test.go,
TestUserDeleteSaysNothingOfReportAddresses; the user form's e-mail help):
deleting a user names no domain - "The domains" read as if one could lose
something - and the e-mail field of the user form is "the user's own
address", not "for notifications". The mockups take the panel's words.

The owner's "проверь, что документация актуальна с кодом" (2026-10-16).
Read-only reviews checked every present-tense claim against the code;
each finding was read in the source before it was fixed here.
architecture.md: held inbound mail has its row from the journal milter,
not the tailer; the antispam action is accept or tempfail, anything else
stops the start; tls-internal's certificate is 0644; the signer logs to
stderr; the log's fingerprint is the inode, not the device; a mail.log
postlogd makes is 0640 (maillog_file_permissions); an unreadable stored
place starts at end-of-file too; the test-message route; no map in page
data; design-first compares whitespace aside; the queue and sasldb2.new
are not backed up; antispam/ under /data; POSTFIX_QUEUE_DIR's desync;
SELFPOST_BACKUP_PASSWORD (the CLI's).
schema-migrations.md: inbound_spam_log's upstream columns (v12),
send_log's sender reason, row 9's client_ip.
security.md: /data/opendkim since 2.9.0 (removed, or the start refused),
sasldb2 under /data/sasl, the trigger for mandatory encryption, the
password minimum counted in characters.
development.md: Staticcheck in CI, the e2e ports 20025 and 20053/udp.
README: the client IP list refuses at MAIL FROM, overrides are per
application. product.md: the optional rspamd sidecar.
Code: validate.AdminPassword counted bytes, so six Cyrillic letters
passed for twelve characters; it counts runes, as the backup password
always did (TestAdminPasswordCountsCharacters). envdoc reads
cmd/selfpost-backup too, and a name kept in a constant. A stale comment
of cmd/panel's run ("three roles").

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Agreed by the owner on 2026-10-13 (the local day, no "UTC" beside a
time); the zone is the container's TZ in .env and Settings only shows it,
his "Да" of 2026-10-17. Mockups c205106.
Every time the panel shows is formatted in time.Local and says no zone:
the logs' Time and the DMARC Received columns, a message's timeline,
Overview's "Updated", Health's certificate and renewal, the filter lists,
DMARC reports and windows, the auto limit's last recalculation. Stored
instants stay UTC. The days counted are the zone's: delivery_log_days and
sender_check_days key their rows by the local date, the sender check cuts
downtime at local midnights (byDay), the log filters' days run from local
midnight to local midnight. Notification mail and the test message write
the zone's abbreviation after a time - they are read away from the panel.
DMARC's one-day window label stays the reporter's (UTC) day.
Settings box 05, Time zone, read-only: the name (UTC without TZ), its
offset, and a TZ the image cannot load said to leave the times in UTC
(time/zoneinfo_unix.go, initLocal) rather than named. TZ is passed by the
compose file ("${TZ:-}"), in .env.example and the guide's table; tzdata is
named in the image (supervisor's python3.13 brings it today). Postfix
takes TZ through import_environment, so mail.log's stamps are the same
zone, which closes the trap the roadmap wrote down: the tailer has always
read them in time.Local.
Tests: a TestMain runs view, handlers, store and cmd/panel in UTC whatever
the machine's zone (as logtail's); TestSettingsShowsTheTimeZone,
TestTimesAreTheContainersZone, TestByDayInTheContainersZone, a Moscow day
in TestQueryInboundSpamFilters; envdoc's pattern takes two-letter names.
e2e time_zone_is_the_containers recreates the stand with
TZ=Europe/Moscow: date says MSK, Settings names the zone and UTC+03:00, a
test message's page gives its time and its mail.log lines in Moscow's.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Agreed with the owner on 2026-10-13 (the panel in a chosen zone, "today"
that zone's day, the UTC labels gone) and settled on 2026-10-16/17: the
container runs in his zone ("Контейнер в моем поясе") - TZ in .env, read
by every program at its start - so the zone is shown on Settings, not
chosen there ("Да"), as the level-1 limit is.
Every mockup loses "UTC": the column heads are Time, Received, Held,
Arrived; a stamp is a date and a time. Settings gets box 05, Time zone,
read-only: the zone, its offset, where it is set, and that every time and
day of the panel is that zone's, as are mail.log's stamps. The help's
Settings topic says so. outlines.json: settings gains the box. check.py: 0

one message from postmaster@ the hostname to an address typed; it opens in
the Outbound log, which follows it (the commit before this; mockups

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Decided by the owner on 2026-10-13 (out of preflight); the sender is his
choice of 2026-10-16 ("Да, адрес годится"); mockups e92769f, e3b2501,
8f0ccf9, the route guard 75f97c9.
Card 09 on Health, in the right stack's static end (the left stack is
polled whole): one recipient and Send. HandleTestMessage (global role)
takes one address (validate.AccountEmail - no list, nothing that reads as
an option), at most ten an hour counted from the send log, writes the
message's send-log row first (store.InsertTestMessage: queued, the
hostname as domain, no application, no queue id), awaits its Message-ID
(logtail.AwaitMessageID) and hands it to sendmail as notifications go
(notify.Mailer.SendWithID: postmaster@ the hostname, signed by the local
socket with the key of the server's own name). The browser lands on the
row; the tailer gives it its queue id from cleanup's message-id= line
(src/cleanup/cleanup_message.c:639) and from then on its delivery lines
its status. Postfix refusing the hand-over removes the row; sendmail out
of time keeps it (postdrop may have queued it). The sweep closes a row
whose id was never seen once it is no longer awaited
(CloseUnmatchedTestMessages); an id awaited past ten minutes is not taken.
Reviewed for security before the commit (2026-10-17): no high or medium;
its three low findings are fixed in this commit (the unmatched row's
close, the awaited id's age, the timeout keeping the row) and the
security.md bullet says how the queue id is matched.
Tests: TestTestMessage (refusals, the row and the page, Postfix refusing,
the hourly ten), TestTestMessageTimeoutKeepsTheRow, TestTestMessageRows,
TestCloseUnmatchedTestMessages, TestAwaitedMessageID,
TestRunGivesTheTestMessageItsQueueID, TestHealthTestMessageCard; e2e sends

The owner, 2026-10-16: "Делай все согласованные" - test-email among them,
its sender his choice of the same day ("Да, адрес годится"); the form is
Health's card 09 (mockups e92769f, e3b2501) and posts to a route under the
page it belongs to, as Re-check DNS and Reload do. The guard's route table
gets the one pattern. Nothing else under internal/web changes in this
commit; the router and the handler follow in the next.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Health's left stack is one polled element (health_stack, swapped whole
every refresh): a form there would lose the address being typed. Card 09
moves under Configuration, the right stack's static end, as Configuration
itself sits outside the poll for its button. On a phone the cards keep the
order of their numbers (data-order). outlines.json rewritten for health.

notifications go - through Postfix, signed with the key of the server's
own name - and opens in the Outbound log, whose page follows it to the
receiving server; ten an hour. The help gets a Test message topic: what

Decided by the owner on 2026-10-13 (in place of preflight), taken up on
2026-10-16; mockups b2dcefc, cc33890, 0feaa55 (his: the greeting on a row
of its own, the name check a tag beside Names).
- The certificate: health.Certificate keeps its names (DNS names, or the
CN without any) and ForHost holds it to SELFPOST_HOSTNAME as a TLS
client does - VerifyHostname over the DNS names, the CN only without
any, as OpenSSL's X509_check_host and so a sending Postfix still take it
(src/tls/tls_client.c:439, 513). A certificate for another name fails;
the tag beside Names says matches / not for the hostname.
- The greeting: postconf -x -h smtpd_banner, read once at the panel's
start like the served certificate's path (main.cf is not rewritten
after), is what smtpd writes after "220 " (src/smtpd/smtpd.c:5979). A
first word other than the hostname warns, with what to set. A fact may
now take the whole row (Fact.Wide, sp-wide) and carry a tag beside its
label (Fact.LabelTag); both on the kit page.
- The proxy: auth.Module.Seen says the address the panel counts sign-ins
against, the peer, and whether X-Forwarded-For was read or left unread
for an untrusted peer; the Configuration card shows "Your address" and,
in the second case, warns that every visitor shares one sign-in limit
and names the /32 (or /128) to put in TRUSTED_PROXY_CIDR.
Tests: TestCertificateForHost (CN-only, DNS names, a wildcard, the CN
ignored beside DNS names), TestSeenAddress, TestHealthSaysWhereItSeesTheViewer,
TestHealthGreetingAndCertificateName; e2e reads the stand's right state on
Health (matches, "220 mail.e2e.test ESMTP", a direct client). go vet + go

The certificate card loses its own "Matches the hostname" row: a tag
beside Names says it - "matches", or "not for the hostname" in red. A
fact's label may carry a tag (sp-facts dt .tag keeps the tag's own type),
shown on the kit page. Help says where the verdict is. check.py: 0

The owner, 2026-10-16, on the mockup: "Может Greeting на всю ширину
карточки?" The facts grid gets sp-wide, a fact over the whole row (shown
on the kit page), and the greeting uses it. The greeting itself is what
this image's Postfix writes: "220 mail.example.org ESMTP"
(build/postfix-config.sh sets smtpd_banner to "$myhostname ESMTP"),
not Debian's longer default. The Configuration card's address sits in a
block of its own above the text. check.py: 0 violations.

Agreed with the owner on 2026-10-13 (in place of csrf-tokens), taken up on
2026-10-16 ("Да"). originAllowed (internal/web/security.go) returns false
in the "neither header" branch: such a POST is answered 403 and logged
like a cross-origin one. It was let through until now as an accepted
risk, which left a browser that sends neither open to a request forged by
any site. A browser that follows Fetch § 3.2 never sends a POST without
Origin; one too old to (Firefox before 70) can no longer save anything.
What posts to the panel without a browser: the e2e suite's client, which
now sends Origin on every form (panelClient.postForm); cmd/panel's tests
already did. Nothing else posts to it (the CLI runs in the container).
Tests: security_test's case of no headers is refused; e2e posts with
neither header and gets 403 (testFormPostWithTheBrowsersOrigin). go vet +
go test (26 packages) and make e2e on the test server for this tree.

Agreed with the owner on 2026-10-13, taken up on 2026-10-16 ("Да"); the
mockup is 1888dce. Both secret downloads - the full backup on Server ›
Backup and a domain's export on its settings - ask for "Your account
password": reauth (handlers_backup.go) checks the signed-in user's own
password with bcrypt, as a password change does, under the same limiter
(auth.AllowPasswordChange: ten in fifteen minutes per user, shared with the
Account form). A wrong or missing one is 401 on the same page with "Your
account password is incorrect.", logged; nothing is sent. The import and
the selfpost-backup CLI are not asked.
Also, the owner's phone screenshot of 2026-10-16 ("кнопка выбора файла не
такая, как в макете. Это косяк?"): the import's file field was a bare
<input type="file"> drawn by the browser ("Browse…"), where the mockup has
Bulma's .file - "Choose a file…" and the name chosen. The template now
follows the mockup; panel.js writes the name into .file-name on change and
at load (testdata/filename_test.js, run by TestPanelJS). No other file
field exists.
Tests: TestSecretDownloadsAskForTheAccountPassword (missing, wrong, right,
the limiter), the export refusals of the settings page with the password,
cmd/panel's restore tests and e2e's backups with it, e2e's refusal of a
backup without and with a wrong password. go vet + go test (26 packages)
and make e2e on the test server for this tree.

The owner, 2026-10-16: "Вариант 1. Но меню выглядит длинной простынёй. Там
бы сделать сворачивание разделов." As the mockup of e0e30e2: the bar's
navbar-menu loses is-active, so Bulma hides it below 1024 px, and the new
touchnav partial (layout.html) takes its place in the brand - Menu, a
<details> whose panel holds Overview, each group as a fold (the current
one open, its page aria-current), and the user's group last with Account,
Help and Sign out (the same POST form as the bar's). The same Show* flags
as the bar decide what is there. panel.css takes the mockup's rules (the
touch navigation, a 1rem gutter for the page and the sibling strip below
1024 px). No script.
The cause, measured, is written in the roadmap row: every width under
1024 px had the always-open menu; "desktop site" (~980 px) added Bulma's
side-by-side columns from 769 px; Bulma's container has no side margin
below 1024 px.
Tests: the Menu marks the current group and page and the bar's menu has
no is-active (TestMenuHighlightsTheCurrentGroupEntryAndSibling), it offers
nothing the bar does not to a domain administrator (TestTouchMenuFollowsTheBar),
the shell's Sign out is counted twice on the password page;

The owner, 2026-10-16, of two ways for the navigation of a narrow screen
(pictures at 390 and 980 px): "Вариант 1. Но меню выглядит длинной
простынёй. Там бы сделать сворачивание разделов."
The cause, measured: the bar's menu was always open (navbar-menu
is-active, no burger), and Bulma lays it out below 1024 px as a sheet of
every section's pages, filling the first screen - on every phone, and on
a phone in "desktop site" mode (about 980 px) under columns that Bulma
puts side by side from 769 px; and a container has no side margin below
1024 px, so the page met the screen's edge.
Now, below 1024 px: the bar's menu is hidden (no is-active), and a Menu at
the right of the brand opens a panel over the page - Overview, then each
section as a fold, the current one open, the user's last (Account, Help,
Sign out). <details> all through: no script, like the folded DNS records.
The page and the strip of sibling pages get a 1rem gutter. From 1024 px
nothing changes. check.py: 0 violations; outlines unchanged.

Cut without asking, as the owner said on 2026-10-15, after his choice of

The owner, 2026-10-16, of three ways to stop a reused queue id reaching an
older row (found by the technical review of inbound-upstream-result, L6):
"1" - enable_long_queue_ids=yes. A short id is the microsecond of arrival
and the queue file's inode in hex (Postfix 3.10.13, src/global/mail_queue.h,
MQID_SH_*) and repeats once the inode comes round; a later message with no
send-log row of its own (port-25 mail, a bounce Postfix sends) could then
rewrite an older Outbound log row of the same id and recipient, its page
could show the later message's stored lines (security.md's known exposure,
"enable_long_queue_ids ... ends it"), and the inbound journal's rows needed
detaching. A long id adds the time in seconds and does not repeat
(MQID_LG_*; proto/postconf.proto: existing queue files keep their names,
postqueue -p gets a wider Queue ID column). Every pattern of the panel
takes both shapes (queueLineRe's long branch, the [0-9A-Za-z]+ of the
others, queueEntryRe) - checked one by one.
Tests: e2e reads a long id on an outbound send-log row
(testExpiredMessageIsClosed) and on an inbound journal row
(testInboundUpstreamDown). go vet + go test (26 packages) and make e2e on
the test server for this tree.

upstream_reply, upstream_at, and a partial index on queue_id. Schema 12.
- The inbound journal milter writes an accepted row with the queue id of
end-of-message and "queued" ("held" when the filter had it held), the
recipient as Postfix logs it (recipientAsLogged), after detaching older
rows of a queue id Postfix uses again; no queue id, no result.
- The tailer: a delivery line no send-log row took goes to the journal -
status, relay= ("" for none), the reply after the first status=, cut to
255 printable bytes, the line's time; queued/held/deferred rows only,
sent and bounced final. qmgr's expiry makes them bounced, keeping the
last reply. cleanup's "removed (" detaches rows of a message never
queued. Addresses in delivery lines are read by Postfix's quoting
(loggedAddress): a quoted RCPT TO cannot end one early.

Findings of the reviews of the row (2026-10-16): a message the filter had
held is "held" in the Upstream column - in the queue, not tried until it is
released - and not "queued"; and a bounced message is said to have bounced
to its sender only when it had a return address (Postfix does not bounce
mail from the null sender). The help's Inbound log topic says both.

The owner, 2026-10-16, a phone screenshot of an outbound message's Delivery
log: "На телефоне при просмотре лога, появляются две полосы. Мы это можем

reply - was at its end, out of sight.
sp-log wraps (white-space: pre-wrap, overflow-wrap: anywhere) and no longer
scrolls; each line is a block, sp-ll, with a hanging indent of 4ch, so the
rest of a wrapped line stands under its start and a new line is told by its
time at the left. The line keeps its newline inside its block, so copied

2.8.x copied the keys from /data/opendkim to /data/dkim and kept the old

(docs/plans/panel-dkim-signing.md, Q2); the owner's "потом режь 2.9.0"
(2026-10-16) makes this that release. The entrypoint now removes the tree
once /data/dkim holds a key, and says so. A /data with keys under the
old tree only - one that never ran 2.8.x - stops the start with a message
to run 2.8.x first, rather than let the panel give the server's own name
a new key its published record would not match; the tree is left as it
was. Gone with it: the copy into /data/dkim.new, the tree's
normalisation, its exemption from the general hand-over, its key link in
drop_links, and the backup's exclusion of "opendkim" (dead: the panel
never sees the tree now).
Tests: e2e TestStartsOnA28Data replaces TestStartsOnA27Data - a /data as
2.8.x left it (both trees, a queue of foreign uids, a rotation due): the
old tree is gone, the key under /data/dkim is the one left, the selector
table names it, the queue is Postfix's by name; TestRefusesA27Data - the

полями."
Server › Settings: the form holds only the left column - 01 Log
retention, 02 Notifications, Save settings under them - so the button
sits under the fields it saves whatever the records' state. The right
column, outside the form, holds what is not a field: 03 Notification
mail (the records of the server's own name) and 04 Sending rate limits
(read-only). The boxes are numbered column by column, as before.
outlines.json rewritten for settings (check.py --write): the form moved
from around the columns into the first one; nothing else changed.
check.py: 0 violations.

The dns_record partial draws a record whose tag is "published" and that
has no "In DNS now" (Record.Folded) as a <details> whose summary is the
head - name, tag, "Show values" - with the host, type and value behind
it, as the mockup of fffee9c. Every other record stays a <div>, open.
One partial, so the outbound domain's page, the inbound domain's and
Settings › Notification mail change together; panel.css takes the
mockup's rules, help.go the help's sentence word for word.
Re-check DNS posts and redirects to the page, which is drawn from the
fresh check: a record that has just turned right comes back folded. No
page that draws records polls them, so nothing has to keep a fold open.
Tests: the dns_record partial folds only a published record and closes
the block it opened (TestDNSRecordFoldsOnlyWhenPublished); the mismatch
test reads the folded head. go vet + go test (26 packages) and make e2e
on the test server for this tree.
CHANGELOG [Unreleased]; roadmap row done, its section says what was
decided.

A record DNS already holds as shown is a <details> whose summary is the
record's head: its name, its tag and "Show values" (ti-eye - the icon
subset has no chevron); the host, type and value open behind it. The
head's note is hidden while folded, so the fold stays one line in a half
column (the server's SPF on Settings); it shows when opened. Missing,
weak, mismatched and unchecked records stay open as before.
Mockups: the kit's dns_record example, out-domain (DKIM and DMARC
folded, SPF open on its mismatch), in-domain (MX), settings (DKIM
folded, SPF missing and open); the help's DNS topic says so. Outlines
unchanged (the block keeps sp-record). check.py: 0 violations.

Cut at the owner's word (2026-10-16, "Выпускай").
The panel signs outgoing mail in a milter of its own (go-msgauth,
relaxed/simple, the login's key on 465/587 and the server's name's on
local mail); OpenDKIM, the syslog relay, the USR1 reload and the From:
parser port are gone. Keys move to /data/dkim (copied once; /data/opendkim
kept for a rollback, left out of backups). The sender check holds Sender:
like From:. go-milter is built patched not to keep every header. The queue
is handed to Postfix's users by name before "postfix check". Commits
005922b..ca3a183 (005922b, faa3c11, c2f63d2, f0dd9f9, 2cfd239, d9d9af3,

On the test server since 2026-10-15 22:48 UTC (2.7.0-post.c2f63d2, now
2.7.0-post.f1d90a2, the same code as this cut): healthy, keys unchanged.
The first rollout (faa3c11) crash-looped five minutes on the queue's owner

Agreed by the owner (2026-10-16): prepare an issue and a small compatible
PR for go-milter (the map emptied when a message starts), with an option
not to keep it proposed; the owner posts them. Then third_party/go-milter
can go.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The security documentation's last open item of panel-dkim-signing (the
owner's decision, 2026-10-16): go-milter v0.4.1 added every header of a
session to a map of its own, emptied only on ABORT, and handed it to
Headers - which no milter of the panel reads. Postfix bounds one header,
not their number, so a message of nothing but headers up to the message
size limit was held whole by the library in the sender check, the signer
and the journal milter on 465/587 and in the inbound journal milter on port
25, where strangers send; the signer's 1 MiB refusal came after it was all
in.
third_party/go-milter is v0.4.1 from the module cache (BSD 2-Clause,
LICENSE kept) with session.go changed: CodeHeader hands the header to
Header and keeps nothing, CodeEOH hands Headers an empty map. PATCHES.md
says what and why, and how to take a new upstream version. go.mod replaces
the module with it; the Dockerfile copies third_party before "go mod
download". TestTheLibraryKeepsNoHeaders holds it through the library's own
client over two messages of one connection. Comments, security.md (the
accepted risk becomes a note), development.md's library table, the plan and
CHANGELOG follow.

The rollout of 0cceb54 to the test server (2026-10-16 04:44 UTC) logged
"postfix/postlog: fatal: the Postfix mail system is not running" and
"error running non-shared postrotate script": the day's rotation was due,
logrotate-loop.sh runs at once when the container starts, and the wrapper
starts Postfix only once the milter sockets are there. Nothing was lost -
no postlogd held the old file, and the one Postfix started a second later
opened the new - but logrotate reported a failure and the loop waited six
hours. The postrotate now runs "postfix reload" only when "postfix status"
says a master runs (Postfix 3.10.13, conf/postfix-script:297-307).
e2e TestStartsOnA27Data also starts on a mail.log whose rotation is due
(a state file of two days before) and wants it rotated with no postrotate
error in the container's log.

The owner's decision (2026-10-16) on the security review's F1: a Sender:
line - the sending agent's, shown beside From: as "on behalf of", and
signed since 2.8.0 - was neither held to the login nor, before, signed: an
application could write its own From: and Sender: ceo@bank.com under this
server's signature. Now, when a message has one, it must be one address
the application may send as, and at most one such line (RFC 5322 § 3.6);
From: is judged first.
The refusal is "550 5.7.1 Sender: <address> - <why>", a send-log row of
reason "sender" (store.ReasonSender), tagged "wrong Sender"; the message
page names the line. The log tailer recovers such a row from cleanup's line
as it does a From: refusal (fromRefusalRe reads either). Help text as in
the design commit d9d9af3; guide, architecture, security and CHANGELOG say
it, security.md keeps Resent-From: (signed, not judged) as an accepted
risk.
Tests: TestSenderLineHeldToTheSameRule (own address, a name, another
application's, a stranger's, two addresses, two lines, From: first), the
recovery of a Sender: refusal line, the tag, the message page; e2e
sender_check_holds_the_sender_line (own Sender: passes and is signed,
another domain's refused at DATA and logged).

The owner's decision (2026-10-16, security review of panel-dkim-signing,
F1): a Sender: line, shown beside From: as "on behalf of", is held to the
same rule when a message has one. The topic says how a system that writes
for people outside the server's domains does it instead (its own From:, the
person in Reply-To:), and the Outbound log topic names Sender: among the
refusals.

architecture § OpenDKIM becomes § DKIM signing (keys, the selector table
and when it is rewritten, the two sockets, what is signed and the limits,
the old tree); the process table, start order, liveness, the mail-path
diagram, § Sender check, Persistence and the restore Resync follow the
code. security.md: the panel signs with the login's key, the keys are the
panel's alone, group selfpost and CAP_KILL as they are now; OpenDKIM's
accepted risks go; new ones: what sendmail(1) submits is signed as the
server, Sender: is signed but not judged (the owner's decision), and
go-milter keeps every header per session, so the signer's 1 MiB refusal
does not bound the library's copy. guide: Health, the container log's
dkim-signer lines, backups, the long-line limit, and upgrading to 2.8.0 -
with the rollback to 2.7.x: its start reads the queue as its own postfix
(uid 101) before it hands the queue over, so the hand-over by name is run
in the 2.7.x image first (measured on a copy of the test server's queue:
postsuper failed before, passed after). development, README, SECURITY,
product, the assumptions register's header: what left the image.

internal/milter/sign.go imports it since stage 1; go.mod still had it as

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The first rollout of faa3c11 to the test server crash-looped: without
opendkim the image's package accounts got other numbers (postfix 101 ->
100, postdrop 103 -> 102), the queue under /data kept the old ones, and
postsuper, which "postfix check" runs as the mail owner
(src/postsuper/postsuper.c:1442), could not open it. Rolled back within
five minutes. The entrypoint now hands an existing queue to Postfix's users
by name before postfix-config.sh, and again after it (own_queue).
Technical review (F1-F10):
- F1 high: a backup of an upgraded installation carried /data/opendkim, a
restore left it root's, and the panel refused every start. The tree is
left out of archives, and the entrypoint makes it the panel's alone
(0700/0600; also the security review's F3 - nothing of 2.8 needs the
group any more; a 2.7.x start re-normalises it).
- F2: List-Unsubscribe-Post is signed (RFC 8058); Sender too (security F1).
- F3: SetServerName keeps the name in lower case - a key written under
"Mail.Example.com" was never found. Only the DKIM side: the SASL realm
is compared as written.
- F4: the signer rewrites the selector table at every start
(WriteSelectors, replacing EnsureServerSigned), and tries again every
10 s while a rewrite fails.
- F5: e2e signature_over_awkward_headers (folded, tab-led, no space, two
To:, 8-bit body, List-Unsubscribe-Post) checked by dkimpy;
TestStartsOnA27Data starts on a 2.7 /data (old key tree, a queue of
foreign numbers) and checks the copied key signs, the old tree's modes
and the queue's owners; unit tests for repeated headers and the header
limit.
- F6: the table's writers are serialised (tableMu).
- F7: the table is read for every message; keys the table no longer names
are dropped from memory.
- F8: the signature's value brings its own space (SMFIP_HDR_LEADSPC gets
none from Postfix, cleanup_milter.c:1085).
- F9: a body line over 998 bytes is logged with its domain: Postfix's SMTP
client breaks it after signing (smtp_proto.c:1266-1274).
- F10: the keys are copied while /data/dkim holds none (not only when it
is absent), after the old tree is made the panel's (an install from 2.6
had another uid); the plan's rollback note says what a rollback keeps.
Security review: F2 a header section over 1 MiB is refused (552 5.3.4)
and the kept headers freed once the block is built - fifty connections of
header-only messages could take the panel down; F5 the shown headers a
message has (Subject, Date, To, Cc, Reply-To, Sender) are over-signed,
only when present, since cleanup adds a missing Date: after the milters.
F1 (holding Sender: to the login like From:) changes what is refused and
waits for the owner.

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

Health: the opendkim process row goes; the Milter sockets card shows the
panel's signer on its two sockets, dkim-signer · applications (sign.sock)
and · notifications (sign-local.sock) - Q3 of the plan; Configuration
says it reloads Postfix. Domain delete: "stop signing mail as the
domain" for the OpenDKIM reload. System log: mail.log is Postfix's log
(OpenDKIM never wrote to it), its sample line goes. Message page: the
sample's OpenDKIM line becomes a qmgr line. Help, sender check: the
From: line is read as a mail program reads it and must be one address;
DMARC holds the signature to it; the sentence the mockup carried twice

.cursor/rules/panel-ui-system.mdc named docs/assets/panel-ui the source of

internal/milter/sign.go: a milter on two sockets (cmd/panel/signer.go):
sign.sock for 465/587, the key of the domain the SASL login belongs to
(Bindings.DomainOf, the sender_login_maps Postfix reads), and
sign-local.sock for the panel's own sendmail(1) mail, the server's name.
go-msgauth/dkim v0.7.0, relaxed/simple, OpenDKIM's dkim_should_signhdrs[]
(libopendkim/dkim.c:223-246) in message order plus From once more; keys
and selectors from the KeyTable the panel writes, a key path outside the
key directory refused; strict - whatever cannot be signed is deferred.
From the sources: Postfix 3.10.13 milter8.c:2329-2400 hands a folded
header \n-separated, so the signer joins its lines with CRLF; inserts are
1-based in cleanup_ins_header() (cleanup_milter.c:1193), so index 0 is the
top, where OpenDKIM puts its own (opendkim.c:3673). go-milter v0.4.1 calls
no Abort when a connection ends, so a watchdog closes go-msgauth's
streaming signer after an hour and a late end of message is deferred.
Postfix: smtpd_milters = sender check, signer, OpenDKIM, journal;
non_smtpd_milters = the signer's local socket, OpenDKIM - both sign every
message until stage 2. disable_mime_output_conversion=yes (default off,
mail_params.h:3088): an 8-bit message is no longer re-encoded after it is
signed.
Tests: unit tests sign and verify folded, tab-led and space-free headers,
an added From:, a changed body, two messages on a connection, odd bodies,
and five cases deferred. e2e: the sink image has python3-dkim (dkimpy
1.1.8-2) and the stand's DNS; on an application's message and on a
notification the two signatures must agree on h=, bh=, c=, s=, a= and each
must pass dkimverify. On the server: make e2e exit 0 (714 s), go vet + go
test 27 packages ok.

Security review (1c6e04b):
- The panel's database and its -wal/-shm were 0644 under a traversable
/data, holding the panel users' password hashes and session token
hashes. store.Open now makes them 0600 (SQLite gives the next -wal/-shm
the database's mode: findCreateFileMode(), unixOpenSharedMemory());
TestOpenKeepsTheDatabasePrivate.
- The entrypoint removes a symbolic link the panel user could leave where
a /data directory, table, map, the queue or mail.log is expected, before
its root steps chmod or create them (drop_links).
- The panel user is 10999:10999, outside the system range: in trixie
useradd gave it group 998, the host's systemd-network on the test
server; bookworm's 999 was the host's systemd-journal.
- security.md said the database was 0640; it was 0644.
Technical review (1c6e04b):
- mail_helpers.go: smtp-sink does add a Received: header, "(smtp-sink)"
(smtp-sink.c:520-531); the "(Postfix)" filter leaves it out.
- CHANGELOG/roadmap: OpenDKIM's signing and From:-parsing code is
unchanged, not all of it; the retry-policy bug predates 3.9 (any
postconf warning); three entries moved from Fixed to Changed, as no
released image had them.
- internal/app/sasl.go: db_dump's stdout alone is parsed.
- mynetworks comment: postinst:180, fset_all_changed.
Tests: on the server, make e2e exit 0 (712 s), go vet + go test 27

The runtime base is debian:trixie-slim, the build stage golang:1.26-trixie:
Postfix 3.10.13 with upstream's 2026 security fixes up to the August
batch, libmilter 8.18.1, OpenSSL 3.5. Every citation of another program in
code, scripts and documents was re-read against the trixie sources
(dev/upstream; bookworm's kept in dev/upstream-bookworm) and updated;
development.md's cited-package table holds the trixie versions.
What the re-reading changed in behaviour:
- logtail: reject lines with sasl_method/sasl_username/sasl_sender
(smtpd_check.c:1019-1026); cleanup's "removed (canceled)" forgets a
port-25 id (cleanup_api.c:363-364).
- internal/postfix/retry.go reads postconf's stdout only: since 3.9 a
deprecated-parameter warning on stderr made one value too many and the
panel fell back to the compiled-in retry policy.
- logrotate-loop.sh: logrotate 3.22 exits 1 when it ignores a config;
the loop refuses on that output whatever the status.
- postfix-config.sh: cyrus_sasl_config_path set explicitly (bookworm's
07_sasl_config.diff is gone); maillog_file_permissions=0640; mynetworks
explicit; Dockerfile: SYNC_CHROOT= in /etc/default/postfix,
opendkim-tools dropped, openssl named, systemd-standalone-sysusers so
cron does not bring the whole of systemd.
- The selfpost group is 10998, outside the system range 100-999: in
trixie a package took 998 and the build failed (owner's decision:
a conflict-free id, the distribution's own ids untouched). The
entrypoint hands /data back by name when the user or the group differs.
Guide, backup refusal text, help (design commit 68ec8b2), e2e.
- smtpd_hide_client_session=yes on smtps and submission (owner's
decision): Received: names no client, TLS, login or protocol; port 25
keeps the full header. e2e checks both.
- test/upstream/opendkim-probe.sh makes keys with openssl genrsa.
Tests: on the server, make e2e exit 0 (674 s, the image built on trixie),
go vet + go test 27 packages ok. CHANGELOG [Unreleased], guide,

Postfix 3.7.11 leaves its 2023 SMTP-smuggling defence off (default "no"
before 3.9, src/smtpd/smtpd.c:807), and the inbound relay's smtp/inet
listener did not turn it on: a "." line ended by a bare LF ended DATA and
what followed was read as the next transaction. The listener now sets
normalize (bare_lf_mask_table, smtpd.c:1656; the DATA loop drops such a
"." line, 3649-3652), the setting Postfix recommends and 3.9's default.
The submission ports keep the default (own-mta-builds, section 5).
Tests: e2e inbound_bare_newline_is_one_message sends the smuggling
sequence over raw SMTP (net/smtp's DotWriter would rewrite the bare LF)
and finds one message at the upstream with the smuggled part inside;
port25 config check asserts the parameter on smtp/inet. On the server:
make e2e exit 0 (511 s), go vet + go test 27 packages ok.
Docs: CHANGELOG [Unreleased] Security, security.md, architecture.md,
guide.md; roadmap: port25-bare-newline, base-trixie and
panel-dkim-signing agreed by the owner in this order.

docs/own-mta-builds-2026-10-15.md weighs patched builds of Postfix and
OpenDKIM against what the panel works around. No Postfix limit needs a
patch (the panel reads it through the interfaces it offers); every limit
worked around is OpenDKIM's, a project with no release since 2018, three
2026 CVEs open in every Debian suite and no one answering (read in
dev/upstream: dkim_process_set runs on a tenant's DKIM-Signature header
in signing mode too). Bookworm is in LTS since 2026-07-12 and its Postfix
3.7.11 lacks the June, August and September 2026 upstream security
batches, which carry no CVE ids.
Proposed as candidates: port25-bare-newline (smtpd_forbid_bare_newline
defaults to no on 3.7; our smtp/inet block does not set it), base-trixie
(postfix 3.10.13; 331 citation lines to re-read), panel-dkim-signing
(go-msgauth/dkim in the panel's milter; OpenDKIM, the syslog relay and
the parser port removed, about 1,500 lines).

The last stage of the 2026-10-12 audit; no cut.
Doc drift: architecture.md (the sender check in § OpenDKIM, the limit:
row's 48 hours, the inbound log and filter-list routes and who may open
them, migrations to 0011 and every table, KitPage as production data,
Reload configuration as a restore writes, the panel's roles counted),
schema-migrations.md (tables and columns since v2), guide.md (a delivery's
lines go at the next prune; INBOUND_JOURNAL_MILTER_SOCKET moved to
architecture.md's internal list), development.md (the env guard, the
deferral the e2e proves, its fixed sleeps), roadmap.md.
Comments say what the code does now; TestBaselineIsTheOnlyMigration is
TestChainStartsAtTheBaseline; the milter package doc names its three
milters.
Dead code gone: view.Facts, dmarc HostedSuggestion and
ValidateHostedAddress, app UpdateMode (each with the test that alone kept
it), the method checks the method-bound routes made dead;
Settings.WithResult calls resultFlash. staticcheck 2026.1 in test.yml on
both modules, clean: the e2e package builds without its tests now (a test
and two constants moved out of non-test files), three findings fixed.
The test moved, TestImageBuildPreservesLogrotateMode, had sat in a
non-test file and never run; run, it failed on the entrypoint (docker run
without a hostname) and now asks with --entrypoint stat.
The test gaps no step named, each closed: follow() with mail.log gone past
blindMin and made again; CheckRestore with a manifest that is not JSON;
the origin check with a port; every /server/ pattern in web.go through
server() and in the routes table (it found GET /server/health/fragment
missing from the table - guarded, not tested); L9 as the owner decided it
on 2026-10-12, the comment on senderSession.Headers and the test passing
an h that holds the earlier messages' From:.
Plan stage 6 ticked; roadmap audit row done, 81/81.
Tested on the test server: go vet + go test of 27 packages, make e2e (all
pass, 513 s) on this tree; staticcheck locally on both modules.

Cut without asking, as the owner said on 2026-10-15.
The supervisord socket is root:supervisor, the panel the group's one member
(M17). Postfix takes TLS 1.2 at least, the client too where TLS is
required; VRFY off; the banner without the distribution; the start refuses
a rate, size or milter timeout that is not a number, under its minimum or
past an int (L31). OpenDKIM logs through the syslog relay to the container
log and oversigns From: (L30). crashexit takes the container down after
five unexpected exits of a mail-path program in ten minutes (L32).
logrotate keeps its state under /data/log. extract-cert.sh refuses what is
not PEM and renames whole files (M21). Plus the findings of both reviews
(a39eda5). Commits dab7715, a39eda5, b09e525.
Rolled out to the test server as 2.5.4-post.95af363 (the same code): the
container healthy, every program RUNNING, syslog-relay among them;
OpenDKIM's start line in docker logs under "syslog: "; the postconf values
as set; /run/supervisor.sock root:supervisor 0770 and the panel reaches it;
/data/log/.logrotate.status written. No migration, schema 11.
CHANGELOG cut; pin 2.6.0 in deploy/docker-compose.yml, README, guide (and
its sample restore message); development.md "from pin" and the stage's row;
roadmap row and recommended order; stage 5 marked shipped in the plan. No
tag.

The owner asked on 2026-10-15 whether our own builds would lift limits we
work around; recorded as a candidate for analysis with the starting points:
the limits met so far, for, against, and the middle ways to compare.

The guide runs it as ./traefik/extract-cert.sh, and git held it 100644 from
its first commit (review of audit stage 5, L3).

- The e2e's numeric-settings test ran a container that passed every gate
and never ended: the good values are checked beside a bad one after
them; each run is named, bounded to a minute and removed.
- The gates refuse a value under the parameter's minimum (a zero window
kills anvil, a zero milter timeout smtpd) and one past an int, in
seconds for a time value (src/global/conv_time.c, src/anvil/anvil.c).
- OpenDKIM waits, five seconds at most, for the relay's socket.
- The relay marks its lines `syslog: `, writes control characters out,
reads into a queue at once and drops past 200 lines a second, saying
how many (security F1, F2; a stuck relay would hold OpenDKIM in
syslog(3)).
- smtp_tls_mandatory_protocols >=TLSv1.2 too.
- extract-cert.sh keeps the old files' group and sets its trap before
mktemp.
- crashexit spares cert-reload; architecture.md "four times running" and
what else exits the container; security.md the restart after five panel
exits and the /dev/log socket.
- Measured against the technical review: smtpd has the selfpost group
(Groups 104 998), so it did reach the supervisor socket before this
stage.
Accepted, reasons in the plan: the logrotate state file in the postfix
user's directory, envdoc_test's reading of `${VAR:-}` only, crashexit's
window pruning untested.
Tested on the test server: go vet + go test of 27 packages, make e2e (all
pass, 592 s) on this tree.

M17: the supervisord control socket is root:supervisor 0770, a group whose
one member is the panel; OpenDKIM and Postfix keep `selfpost` for the files
under /data and no longer reach the socket.
L30, read in OpenDKIM 2.11.0~beta2's source first: it logs through
syslog(3) only and has no Logfile option, and nothing in the container
served /dev/log. internal/syslogrelay (the panel binary with
-syslog-relay=/run/syslog/log, program syslog-relay before OpenDKIM,
/dev/log a link to its socket) passes the datagrams to stdout, error and
worse marked. opendkim.conf: Syslog yes, Canonicalization relaxed/simple,
OversignHeaders From (RFC 6376 § 3.4, § 8.15). e2e: OpenDKIM's start line
reaches the container log; every program RUNNING; DKIM verifies.
Tested on the test server: go vet + go test of 26 packages, make e2e (all
pass, 626 s) on this tree.

Cut without asking, as the owner said on 2026-10-15.
Signing in costs the same for an unknown name (M8) and ends the session the
browser presented (L16); the Account password check has its own limit
(L15). The HTTP server bounds the request, the answer and idle connections;
the full backup moves its own deadline (L14). Monitoring refreshes are
scheduled from htmx:afterRequest with a back-off and a 30 s timeout, and a
lost session sends htmx to sign-in (M11). The Outbound log clamps its page
(L10) and filters by status and day; the multiplier refuses NaN (L11); a
rate-limited refusal is red (L18); Recalculate asks before it drops an
unsaved edit (L19); Reload configuration writes what a restore writes and
removes the keys of deleted domains (L13, L17). The cards layout orders by
number. A notification is owed to each recipient (migration 0011). A DNS
outage is unknown, each resolver with its own time (M14, M15). DMARC
reports too large are refused for their size. An inbound upstream has one
TLS mode, changed for all its domains (L5). Plus the findings of both
reviews (eaa7de0). Commits 07be0cf, 643892a, ca876c1, 80e3979, 2b8e0c0,
b90a2f0, eee089a, 006bed7, 32dfe4a, eaa7de0.
Rolled out to the test server as 2.5.3-post.eaa7de0 (the same code):
migration 0011 applied, schema 11; all programs RUNNING, the container
healthy. Resync's key cleanup checked against the live data: every key
directory is a domain's or the hostname's, nothing to remove.
CHANGELOG cut; pin 2.5.4 in deploy/docker-compose.yml, README, guide (and
its sample restore message); development.md "from pin" and the stage's row;
roadmap row and recommended order; stage 4 marked shipped in the plan. No
tag.

- Two inbound domains on one upstream could never change its TLS mode,
each save refused for the other (medium): SetTransportAs changes the
mode for every domain on the upstream when the one saving may change
them all; a domain user who may not is refused with the mode, not the
other tenant's domain name (security F1: the first version named it).
- A deletion's leftover DKIM key is removed by Resync (Reload
configuration, a restore's first start) for names no domain has.
- The backup's write deadline moves before Check.
- hasUnsavedEdit skips password and file fields and compares a multiple
select's options; htmx.config.timeout 30 s, so a refresh never answered
ends and is tried again; a failed refresh's promise is handled.
- An empty filtered Outbound log says no message matches the filters.
- The dummy bcrypt hash is made at start; a DMARC part over 8 MiB is
refused for its size like the other two limits.
- Health's Configuration box says what Reload writes (design first,
32dfe4a).
- Docs: CHANGELOG, guide § Inbound, security.md (the shared upstream's
mode, the profile form's "username taken"), architecture.md (owed to an
address), the plan's notes corrected.
Tests: the shared upstream (service, handler), the leftover key, all eight
Health boxes ordered, the subject from before migration 0011, the new JS
cases.
Tested on the test server: go vet + go test of 25 packages, make e2e (all
pass, 636 s) on this tree.

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

The cards layout (owner, 2026-10-13; the mockup first, b90a2f0): box_open
writes data-order for a box with InCards and a number, and panel.css orders
by it up to twelve - Health's eight and the kit's three.
TestCardsBoxesCarryTheirNumberAsTheirOrder reads the rendered pages.
Notifications (owner, 2026-10-14): migration 0011, notify_addressees. open
sends a subject's first message to every recipient and records who was
handed it; followUp, on every check while the subject is open and still
wrong, hands it to the owed and untold who are still recipients; closed
sends the end to the told (all recipients for a subject from before the
table). Tests: a failed copy goes out at the next check, once; the hourly
ceiling holds one back; a user added mid-subject hears nothing of it.
Also in the roadmap, from the owner today: dns-record-collapse,
notification-mail-recheck, settings-save-row (agreed, design first).
Tested on the test server: go vet + go test of 25 packages, make e2e (all
pass, 644 s) on this tree.
