 ## [Unreleased]
 
+## [2.13.1] - 2026-10-17
+
+The documents and the panel's words checked against the code. No migration;
+schema 12.
+
+### Fixed
+
+- **A panel password's twelve characters are characters**: the minimum
+  counted bytes, so six letters of a non-Latin alphabet passed for twelve.
+  It counts characters now, as the backup password always did. Passwords
+  already set are not affected.
+
+### Changed
+
+- **The panel and its mockups say the same** (docs-audit): an inbound
+  domain's MX box says when it was checked and its side menu links the
+  domain's Inbound log; a deferred message's history ends with the wait in
+  the queue; Overview says it refreshes on its own; DMARC's hint for an
+  unaligned third party reads as the mockup. Help says what the code does:
+  an application's password is kept by the server so an export can carry
+  it, every password check of a backup counts, a password set for another
+  user signs them out everywhere, the limit mail is daily per sending
+  domain, and a domain administrator is no longer shown the Filter lists
+  topic (their page is the global role's).
+
+### Documentation
+
+- The documents checked against the code (docs-audit, 2026-10-17): the
+  guide, architecture, schema-migrations, security, development, README and
+  product say what the code does.
+
+## [2.13.0] - 2026-10-17
+
+The panel in the container's time zone. No migration; schema 12.
+
+### Added
+
+- **The panel in your time zone** (local-time): set `TZ` in `.env` (an IANA
+  name, e.g. `Europe/Moscow`) and every time the panel shows, every day it
+  counts - today on Health, the statistics' days, the days of the log
+  filters - and the stamps of `mail.log` are that zone's. The screens no
+  longer write "UTC" beside a time; **Server › Settings** names the zone in
+  a new read-only box. Unset, it is UTC as before. Changing it is a
+  restart; days counted before stay the old zone's.
+
+## [2.12.0] - 2026-10-17
+
+A test message from Server › Health. No migration; schema 12.
+
+### Added
+
+- **A test message from Server › Health** (test-email): one message to an
+  address you type, from `postmaster@` the hostname, the way notifications
+  go. The page that opens is its row in the Outbound log, which follows it
+  to the receiving server. It tests the server's own path, not a domain's.
+  Global role, ten an hour.
+
+## [2.11.0] - 2026-10-16
+
+Health checks the certificate's name, Postfix's greeting and the reverse
+proxy. No migration; schema 12.
+
+### Added
+
+- **Server › Health checks three things it did not** (health-setup-checks):
+  whether the TLS certificate is for the server's own name - a tag beside
+  its names, and a failure when it is not, since a client that checks the
+  name refuses it however valid it is; Postfix's greeting, the `220` line,
+  which must name the hostname; and the address the panel sees your browser
+  at, warning when a reverse proxy it does not trust stands in front - every
+  visitor then shares one sign-in limit - and naming what to put in
+  `TRUSTED_PROXY_CIDR`.
+
+## [2.10.4] - 2026-10-16
+
+The origin check is strict. No migration; schema 12.
+
+### Security
+
+- **A change with no word of where it came from is refused**
+  (origin-strict): a `POST` that carries neither `Sec-Fetch-Site` nor
+  `Origin` is answered 403, as a cross-origin one is. It was let through
+  before, as an accepted risk, which left a browser that sends neither open
+  to a request forged by any site. Every current browser sends `Origin` with
+  a form; a browser too old to (Firefox before 70) can no longer save
+  anything in the panel.
+
+## [2.10.3] - 2026-10-16
+
+The backup asks for your password. No migration; schema 12.
+
+### Changed
+
+- **A backup and a domain's export ask for your password** (backup-reauth):
+  both downloads take the signed-in user's account password, checked like a
+  password change and under its limit, so a stolen session or a panel left
+  open no longer hands over the server's every secret.
+
+### Fixed
+
+- **The file field of a domain's import is drawn as designed**: Bulma's
+  file button and the name of the file chosen, not the browser's own
+  "Browse…".
+
+## [2.10.2] - 2026-10-16
+
+The panel on a phone. No migration; schema 12.
+
+### Changed
+
+- **A narrow screen gets a Menu** (phone-desktop-mode): below 1024 px - a
+  phone, a phone in "desktop site" mode, a tablet, a narrow window - the
+  navigation was a sheet of every section and page, always open, filling
+  the first screen. It is now *Menu* at the right of the header, which opens
+  the sections as folds, the current one open, the account's entries last;
+  no script. The page no longer meets the screen's edge. From 1024 px
+  nothing changes.
+
+## [2.10.1] - 2026-10-16
+
+Postfix's queue ids no longer repeat. No migration; schema 12.
+
+### Fixed
+
+- **Queue ids no longer repeat**: Postfix makes long, non-repeating queue ids
+  (`enable_long_queue_ids=yes`). A short id - the microsecond of arrival and
+  the queue file's inode - came round once the inode did, and a later message
+  could then rewrite an older row of the Outbound log with the same id and
+  recipient, put its lines on that row's page, or reach the Inbound log's
+  row of an earlier message. New ids read like `3Pt2mN2VXxznjll`; mail
+  already in the queue keeps its short id; Outbound › Queue's Queue ID
+  column is wider.
+
+## [2.10.0] - 2026-10-16
+
+Inbound › Log says what became of accepted mail: the upstream's answer,
+its last reply and the host that gave it. Migration `0012`; schema 12.
+Nothing for an operator to do.
+
+### Added
+
+- **Inbound › Log shows what the upstream answered** (inbound-upstream-result,
+  [the plan](docs/plans/inbound-upstream-result.md)): an *Upstream* column
+  beside the decision - *queued*, *held*, *sent*, *deferred* (a greylisting, an
+  upstream that cannot be reached), *bounced* (refused, or expired in the
+  queue) - opening the last reply, the host that gave it and when. Read from
+  the delivery lines of `mail.log`, one update of the row per attempt; the
+  lines of port-25 mail are still not stored. Rows logged before have no
+  result. Migration `0012`, schema 12.
+
+## [2.9.1] - 2026-10-16
+
+Log panes read on a phone. No migration; schema 11.
+
+### Fixed
+
+- **Log panes wrap their lines instead of scrolling sideways**: a phone drew
+  two scroll bars over the Delivery log of a message, and the end of a
+  delivery line - `status=` and the reply - was out of sight. A long line
+  wraps, the rest indented under its start; copied text keeps one line per
+  line. The Delivery log, System log and the queue's listing.
+
+## [2.9.0] - 2026-10-16
+
+The panel's DNS records read faster: a record DNS already holds as shown
+is one line, its values on request. Server › Settings puts its Save button
+under its own fields and can re-check the records of the server's own
+name. `/data/opendkim`, which 2.8.x kept for a rollback to 2.7.x, is
+removed at the first start; an installation still on 2.7.x goes through
+2.8.x first (guide, § Upgrading). No migration; schema 11.
+
+### Changed
+
+- **A DNS record DNS already holds as shown is folded** (dns-record-collapse):
+  on an outbound domain's page, an inbound domain's and in Server ›
+  Settings › Notification mail, a *published* record is one line - its
+  name, its tag and *Show values*, which opens the host, type and value to
+  copy them again. A record that is missing, weak, wrong or not checked
+  stays open as before, with *In DNS now* where it differs. A `<details>`
+  block, no script; *Re-check DNS* draws the page again, so a record that
+  has just turned right comes back folded.
+- **Server › Settings: *Save settings* sits under the fields it saves**
+  (settings-save-row): the form is the left column - Log retention,
+  Notifications, the button - and the right column holds what is not a
+  field, Notification mail and the read-only Sending rate limits. Before,
+  the button stood under both columns, after a long gap whenever the
+  records of the server's own name were open.
+
+### Added
+
+- **Re-check DNS on Server › Settings** (notification-mail-recheck): the
+  records of the server's own name can be checked again where they are
+  shown, as a domain's can on its page; the Notification mail box says when
+  they were checked. Before, the only way was Re-check DNS on Server ›
+  Health, which nothing on Settings pointed to. `POST
+  /server/settings/dns-recheck`, global role.
+
+### Removed
+
+- **`/data/opendkim`, the key tree of 2.7.x** (panel-dkim-signing, as
+  planned for the release after 2.8.0): 2.8.x copied its keys to
+  `/data/dkim` and kept it for a rollback to 2.7.x; the first start of
+  this image removes it once `/data/dkim` holds a key, and says so. A
+  `/data` whose keys are under the old tree only - one that never ran
+  2.8.x - stops the start rather than give the server's own name a new
+  key: start 2.8.x once first (guide, § Upgrading). The copy and the
+  backup's exclusion of the tree went with it. A rollback from here goes
+  to 2.8.x; to 2.7.x only through a 2.7.x backup.
+
+## [2.8.0] - 2026-10-16
+
+The panel signs outgoing mail with DKIM itself, and OpenDKIM - a 2018 beta
+with open 2026 CVEs - has left the image. Keys, selectors and DNS records do
+not change; the first start copies the keys to `/data/dkim`. The sender
+check holds a `Sender:` line too. Nothing for an operator to do; a rollback
+to 2.7.x needs one command first (guide, § Upgrading). No migration;
+schema 11.
+
 ### Added
 
 - **The panel signs outgoing mail with DKIM itself** (panel-dkim-signing,
-  stage 1 of [the plan](docs/plans/panel-dkim-signing.md)): a milter of the
-  panel's on two sockets, one for applications' mail - signed with the key of
-  the domain the login belongs to - and one for the panel's own, signed with
-  the server's name. `relaxed/simple`, RFC 6376 § 5.4.1's headers and `From`
-  once more, as OpenDKIM signs; strict. Until OpenDKIM leaves the image both
-  sign every message, and the e2e suite holds the two to the same `h=` and
-  `bh=` and has dkimpy - an independent implementation - verify each.
+  [the plan](docs/plans/panel-dkim-signing.md)): a milter of the panel's on
+  two sockets, one for applications' mail - signed with the key of the
+  domain the login belongs to - and one for the panel's own, signed with the
+  server's name. `relaxed/simple`, RFC 6376 § 5.4.1's headers and `From`
+  once more, as OpenDKIM signed; strict. Before OpenDKIM left, both signed
+  every message on the e2e stand and agreed on `h=` and `bh=`; dkimpy - an
+  independent implementation - verifies the panel's signature on every run.
+  Beyond what OpenDKIM signed: `Sender` and `List-Unsubscribe-Post` (RFC 8058
+  wants it signed for one-click unsubscribe), and the shown headers a message
+  has - Subject, Date, To, Cc, Reply-To, Sender - named once more, so that
+  one added on the way breaks the signature. A header section over 1 MiB is
+  refused (`552 5.3.4`); a body line over 998 bytes, which Postfix breaks on
+  delivery, is logged with its domain.
+
+### Removed
+
+- **OpenDKIM** - a 2018 beta with open 2026 CVEs and no maintainer - and what
+  SelfPost kept around it: the syslog relay and `/dev/log`, the reload by a
+  signal through supervisord, the port of OpenDKIM's `From:` parser.
+  Server › Health shows the signer's two sockets in its place.
+
+### Changed
+
+- **The DKIM keys moved to `/data/dkim`** and are the panel's alone (0600):
+  the first start copies them from `/data/opendkim`, which is kept, the
+  panel's alone as well, for a rollback to 2.7.x, and left out of backups.
+  Keys, selectors and DNS records do not change. The KeyTable and
+  SigningTable are gone; a selector table the signer reads takes their
+  place, rewritten from the database at every start. `OPENDKIM_DIR` and
+  `OPENDKIM_SOCKET` are gone.
+- **The sender check reads `From:` as a mail program does** and no longer as
+  OpenDKIM did: the line must be one address at a domain the application
+  may send as, and the 256-byte limit of OpenDKIM's buffer goes. The key is
+  the login's, so no `From:` line can choose another tenant's.
+- **A `Sender:` line is held to the same rule as `From:`** when a message
+  has one - the address a mail program shows as "on behalf of". A message
+  with another domain's address there, or with two `Sender:` lines, is
+  refused with `550 5.7.1 Sender: …`, tagged `wrong Sender` in the
+  Outbound log. A system writing for people outside your domains puts its
+  own address in `From:` and theirs in `Reply-To:`.

+  made when a domain is added and an existing one is reused, never
+  overwritten: that would invalidate the record already published
+  (`EnsureKey`). A domain export carries the key and an import writes it. A
+  deleted domain's key directory is removed once the selector table no
+  longer names it; one a deletion had to leave, Reload configuration removes
+  (`Service.Resync`).
+- **The selector table** — `/data/dkim/selectors`, a line `<name> <selector>`
+  for every name the server signs, sorted, written whole from the database
+  and renamed into place (`Keys.Rebuild`). It is rewritten when a domain is
+  added, deleted or imported, by Server › Health › Reload configuration,
+  after a restore, and at every start of the signer before it serves
+  (`WriteSelectors`): Postfix waits for the signer's sockets, so no message
+  meets a table from before - one a rewrite cut short left, the first start
+  of `2.8.0` without one, or one naming the old selector after a changed
+  `DKIM_SELECTOR_DEFAULT`. A rewrite at start that fails is tried again every
+  10 seconds; meanwhile the signer defers what it finds no key for, and the
+  pages stay up. Each role builds a domain service of its own, so the
+  writers are serialised by a mutex (`tableMu`): a writer that read the
+  registry before another's domain was added cannot write after it.
+- **The signer reads files, not the database.** The panel's one SQLite
+  connection is shared with the pages, and a long query would hold up mail.
+  It reads the table for every message (a few lines; a stamp of time and
+  size would miss a rewrite of the same size within one tick of the file
+  system's clock) and a key again when its file's time or size changes; a key
+  the table no longer names is forgotten. Nothing is reloaded.
+- **The panel's alone.** All of `/data/dkim` is `panel:panel`, directories
+  `0700`, files `0600`, set by the entrypoint at every start: no group, no
+  other program reads it.
+- **Two sockets, both strict** (`default_action=tempfail`, so while the role
+  does not answer mail waits, never goes unsigned):
+  `DKIM_SIGN_SOCKET` (`/run/selfpost/sign.sock`) for what applications send
+  on 465/587, signed with the key of the domain the SASL login belongs to -
+  `{auth_authen}`, then `Bindings.DomainOf`, the `sender_login_maps` file
+  Postfix and the sender check read; `DKIM_SIGN_LOCAL_SOCKET`
+  (`/run/selfpost/sign-local.sock`) for what the panel itself submits with
+  `sendmail(1)` (`non_smtpd_milters`), signed with the key of the server's
+  name. The socket a message comes through, not the absence of a login,
+  decides that the server's key may sign it.
+- **The server's own name** (`SELFPOST_HOSTNAME`) has a key and a line in the
+  table without being a row of the registry (`domain.Service.SetServerName`):
+  the panel's notifications are sent as `postmaster@` that name and signed
+  with it. The name is kept in lower case for DKIM, as the signer finds keys
+  by the name in lower case; the SASL realm, which defaults to the hostname,
+  stays as written. No application can use it as an envelope sender - the
+  sender map is built from the registry - and since `2.4.0` none can have a
+  message signed as the server by writing it into `From:` either: the sender
+  check holds the header against the login (§ Sender check). A sending
+  domain of the same name shares its key and selector with the server;
+  deleting that domain leaves the server signed under the default selector,
+  which is the same key only if that was the domain's.
+- **What is signed** — `relaxed/simple`, `rsa-sha256`, with
+  `github.com/emersion/go-msgauth` v0.7.0 (`dkim`). `h=`: every header of
+  the message whose name is in RFC 6376 § 5.4.1's list as OpenDKIM's
+  `dkim_should_signhdrs[]` held it, and `Sender` and `List-Unsubscribe-Post`
+  besides (`signHeaders`), each occurrence, in message order; then, once
+  more, each of `Subject`, `Date`, `To`, `Cc`, `Reply-To` and `Sender` the
+  message has (`overSign` - only those present: Postfix's cleanup adds a
+  missing `Date:` after the milters, out of their sight, and a name in `h=`
+  the message lacked would break the signature over the one added); then `From` once more, last (`signLines`). Each header is hashed as
+  Postfix will deliver it: the value with its leading space (the signer asks
+  for `SMFIP_HDR_LEADSPC`), the lines of a folded one joined with CRLF. The
+  signature is inserted at the top, above Postfix's own `Received:`, as
+  `DKIM-Signature: ...`. `disable_mime_output_conversion=yes`
+  ([build/postfix-config.sh](../build/postfix-config.sh)): an 8-bit message
+  is delivered as it was signed, not converted to 7-bit for a server that
+  does not announce 8BITMIME.
+- **Limits.** What cannot be signed - no line in the table, no key file, a
+  login with no domain, a read error - is deferred. A header section over
+  1 MiB is refused, `552 5.3.4`: the signer holds it whole until the body
+  starts. A body line over 998 bytes is logged (`dkim-signer: <domain> ...`)
+  and the message goes on: Postfix's SMTP client breaks such a line on
+  delivery (`smtp_line_length_limit`), and the signature will not verify. A
+  message has an hour from the end of its headers to its end - go-milter
+  v0.4.1 tells a session nothing of a dropped connection - after which it is
+  deferred, never signed over part of its body.
+- **Logs** go to the panel's stderr, the container's log, as
+  `panel: … dkim-signer:` lines; nothing is written to `mail.log` (nor did OpenDKIM write there).
+- **The old tree,** `/data/opendkim` - the keys, `KeyTable` and
+  `SigningTable` until `2.8.0`, shared with OpenDKIM through group
+  `selfpost`. `2.8.x` copied its keys to `/data/dkim/keys` at its first
+  start and kept it for a rollback to a 2.7.x image; since `2.9.0` the
+  entrypoint removes it once `/data/dkim` holds a key, and a `/data` with
+  keys under the old tree only - one that never ran 2.8.x - stops the start
+  (the server's name would otherwise get a new key and its published record
+  would no longer match). Under 2.8.x it was the panel's alone, like the
+  new one, and left out of backups.

A domain's report address is one of three choices, set in its Domain settings: no reports (the default for a new domain), the SelfPost hosted address (an address on this server whose reports are parsed and shown under DMARC reports; offered only while hosted reports are enabled on the server), or an address typed for the domain (an ordinary mailbox that receives the raw XML; a button fills in your own profile e-mail). When the typed address is on another domain than the one sending, that domain must publish a report-authorization record, or providers will not send; the domain's page shows it with the other DNS records and checks it. In the tables pass means SPF or DKIM passed and aligned, fail means neither did, and your own server shows as <em>this relay</em>. A fail from any other source is someone else sending as your domain — a forwarder, an application you forgot, or abuse — so do not tighten <code>p=</code> until that sender is fixed or removed. A domain administrator reads the reports of their own domains.</p></div>

           <div class="sp-help-topic" id="filter-lists"><h3>Filter lists</h3><p>Two lists for the whole server that correct the spam filter by hand. An entry is a sender address, a sender domain — that domain, not its subdomains — or a client address or network in CIDR form. A sender on the Deny list is refused outright. A sender on the Allow list is given a weight no spam score outweighs, so the filter lets it through. The sender's address is whatever the sending server says it is - anyone can claim to be a sender you allow - so allow a client address or network where you can, and a sender address only for mail you would rather receive forged than lose. When entries of both lists match one message, <strong>Deny wins</strong>.<br><br>SelfPost does not apply the lists itself: it writes them as files under <code>/data/antispam/</code>, and rspamd rereads a file within seconds of a change. With the spam filter off the lists are kept and can be edited, but nothing reads them. The sender matched is the envelope sender — the one in the log — not the From line a mail program shows. Matched counts the messages in the Inbound log that the entry decided, so it reaches back as far as the log does; never means not once in that time, and such an entry is one to consider removing.</p></div>

The Postfix queue is not in it. The backup is taken while the server is running, and Postfix keeps moving messages through the queue, so a copy could hold a message twice or miss it; mail still waiting for delivery is therefore not carried over, and a restored server starts with an empty queue.

Until then the panel refuses to make a backup and names the file, rather than hand over an archive without the key. It holds secrets, so leave Encrypt with a password ticked: the file is sealed as <code>.spbk</code>, the password is not stored, and without it nothing can be recovered. To restore, unpack it into an empty project directory (decrypt a <code>.spbk</code> first with <code>selfpost-backup -decrypt</code>) and start the same SelfPost version that made it; the panel refuses data from another version.

Postfix serves its own copy of the mounted file and looks for a renewed one once a day by default; until it takes one up, the card shows it as a renewal waiting, and warns once it has waited longer than that check allows - the container log's cert-reload lines say why. It warns 14 days before expiry unless a renewal is already waiting, and fails once expired, or when the file is missing or unreadable — clients that verify certificates then refuse to connect.</p></div>

It warns 14 days before expiry unless a renewal is already waiting, and fails once expired, or when the file is missing or unreadable — clients that verify certificates then refuse to connect.

The page that opens is its row in the Outbound log: it shows whether the receiving server took it, put it off or refused it, with the lines of <code>mail.log</code>. Whether it then reached the inbox or the spam folder only the mailbox can say. The global role sends it, at most ten an hour.</p></div>

A domain's report address is one of three choices, set in its Domain settings: no reports (the default for a new domain), the SelfPost hosted address (an address on this server whose reports are parsed and shown under DMARC reports; offered only while hosted reports are enabled on the server), or an address typed for the domain (an ordinary mailbox that receives the raw XML; a button fills in your own profile e-mail). When the typed address is on another domain than the one sending, that domain must publish a report-authorization record, or providers will not send; the domain's page shows it with the other DNS records and checks it. In the tables pass means SPF or DKIM passed and aligned, fail means neither did, and your own server shows as <em>this relay</em>. A fail from any other source is someone else sending as your domain — a forwarder, an application you forgot, or abuse — so do not tighten <code>p=</code> until that sender is fixed or removed. A domain administrator reads the reports of their own domains.</p></div>

Four things are reported. A sending domain's SPF, DKIM or DMARC record stops matching: sent once two hourly checks in a row have found it so, and once more when the record matches again. A level-2 rate limit refuses mail: sent at the first refusal, then at most once a day for the same sending domain. The TLS certificate is 14 days from expiry, and again at 3 days if it is still the same certificate. A message has waited in the queue for more than three days, with one more message when none is left. A global user is told all of it; a domain administrator is told about the DNS records and limits of their own domains.<br><br>Each user turns notifications on or off under Account and needs an e-mail there; Server › Settings turns them off for everyone. They are the panel's own mail: not rows of the Outbound log, and not counted against any limit.<br><br>For that mail to arrive, the server's own name needs two DNS records of its own, as each of your domains does: a DKIM key, which the panel generates and signs notifications with, and an SPF record, <code>v=spf1 a -all</code>. Server › Settings gives both with the values to publish and whether they are in place, and its Re-check DNS checks them again once they are published; Server › Health shows them too. Without them notifications are still sent, and a receiver may file them as spam. Mail of your domains does not depend on either.</p></div>

+**Status:** shipped `2.10.0` (2026-10-16).
+
+## Problem
+
+The owner, 2026-10-16: "Нам не хватает в журнале для Inbound ответа
+upstream. Не понятна судьба письма: принято, отклонено, хост не доступен и
+пр."
+
+Inbound › Log shows what port 25 decided - accept, reject, tempfail - and
+nothing after it. Its help says so ("Accept says what this server did, not
+what the upstream did with the message afterwards"). The answer is in
+`mail.log`: Postfix's `smtp` client logs every attempt to hand a message to
+its upstream as `<id>: to=<…>, relay=<host>[ip]:port, …, dsn=…, status=sent
+(250 …)` - or `deferred (451 4.7.1 Greylisted …)`, `deferred (connect to …:
+Connection refused)` with `relay=none`, `bounced (… said: 550 …)` (Postfix
+3.10.13, `src/global/log_adhoc.c`; `relay=none` when there was no session,
+`src/smtp/smtp_trouble.c:273, 421`). The tailer reads those lines for the
+outbound log and, finding no send-log row for a port-25 queue id, drops
+them; the journal row does not even hold the queue id.
+
+## Decision
+
+The owner, asked whether the result goes in the row or on a page of its own
+per message: "Пока только результат. Отдельная страница в план в случае
+появления потребности." So: the row carries the result and the last reply;
+no stored `mail.log` lines for port-25 mail (delivery-log-storage left them
+out on purpose: a stranger sets the rate). A page per inbound message, with
+every line, is for later, if the result is not enough.
+
+## Design
+
+- **Schema, migration 0012:** `inbound_spam_log` gains `queue_id`,
+  `upstream_status` (`''`, `queued`, `sent`, `deferred`, `bounced`),
+  `upstream_relay`, `upstream_reply` and `upstream_at`; an index on
+  `queue_id` for rows that have one. Rows written before have none and show
+  "—".
+- **The milter** writes an accepted row with the queue id it already reads
+  at end-of-message (`{i}`, for the filter's signature) and `queued`. The
+  row is in the database before the message is queued, so before any
+  delivery line.
+- **The tailer:** a delivery line whose queue id has no send-log row is
+  offered to the journal: the rows of that queue id and recipient take the
+  status, the relay (empty for `none`), the reply (printable, at most 255
+  bytes) and the line's time. One update per attempt, no new row; the
+  journal's caps stand. qmgr's `status=expired, returned to sender` makes a
+  queued or deferred row `bounced`, its reply saying it expired after the
+  last one.
+- **The page:** an Upstream column after Decision (mockup `5348330`): a
+  plain `queued` tag, or a tag opening an "Upstream" sheet - host, reply,
+  when, and what follows for deferred and bounced. Refused rows "—".
+- **Docs:** help (word for word with the mockup), guide § Inbound log,
+  architecture (journal and tailer), security (what is stored from the
+  upstream and at what rate), CHANGELOG.
+
+## Reviews (2026-10-16)
+
+A technical and a security review of the tree before the commit; what each
+finding became:
+
+- *A quoted RCPT TO* (both): the milter kept `"owner"@x` as given, every line
+  says `owner@x` - the row never matched. Now `recipientAsLogged`, as the
+  outbound milter does.
+- *A forged line through a quoted local part* (security, medium): `to=<…>`
+  was read up to its first `>`; a local part in quotes may hold `>`, `,`,
+  `status=`. Port 25 refuses the one that would reach another row (an `@` in
+  the local part is a routed address: `src/trivial-rewrite/resolve.c:467`,
+  `src/smtpd/smtpd_check.c:1724`, `allow_untrusted_routing=no`), and the
+  pattern now reads addresses by Postfix's quoting all the same
+  (`loggedAddress`).
+- *Held mail* (technical): a message the filter had held showed `queued`,
+  "not tried yet", for as long as it stayed held. Now `held`, a status of its
+  own (the CHECK of 0012, not shipped yet).
+- *Rows that never close, and queue ids that repeat* (both): before writing
+  a message's rows the milter detaches older rows of its queue id; cleanup's
+  `removed (canceled)` detaches rows of a message never queued; an empty
+  `{i}` writes no result.
+- *A bounce of null-sender mail* (technical): "The sender was sent a
+  bounce" is wrong there - Postfix does not bounce a bounce. The sheet says
+  so.
+- Accepted, said in security.md: a row whose insert waited past the milter's
+  30 s timeout can miss its first line and stay `queued`. Not of this row:
+  an old send-log row of a reused queue id and the same recipient takes the
+  line first (sendlog.go, as before).
+
+## Steps
+
+- [x] Migration 0012, store: write the queue id, update by queue id and
+  recipient, read the result back.
+- [x] Milter: the queue id and `queued` on accepted rows.

+  from the old path, which the move leaves as a copy until the next release
+  - the keys as they were at the upgrade: a domain added under 2.8.x is not
+  in that tree, and 2.7.x sends its mail unsigned; one re-added under 2.8.x
+  has another key there. 2.7.x reads the queue as its own postfix (uid
+  101) before it hands it over, and 2.8.0 left it to uid 100: the guide
+  (§ Upgrading) gives the hand-over by name to run in the 2.7.x image first,
+  measured on a copy of the test server's queue. Going forward again after
+  a rollback, a domain added under 2.7.x has its key only in the old tree:
+  copy its directory into `/data/dkim/keys` (removing `/data/dkim` instead
+  copies the old tree again and loses the keys of domains added under
+  2.8.x).
