docs: machine requirements from load, every option, 768 MB with the spam filter

Owner, 2026-10-19: "Мы рассмотрели все комбинации опций поставки? Почему со
спамом нужна машина с 1 ГБ ОЗУ? 768 МБ не хватит? 512 МБ не хватит?" The
first version measured one configuration at rest and set the host column by
estimate. Now:

- The options and how they combine: 587 (no cost at rest), port 25 (one
  listener for the relay and DMARC), the rspamd sidecar (needs port 25; an
  external rspamd costs nothing here), the proxy (host program or a
  deploy/ container).
- Measured under load on the test server (dev/server/loadmem.sh, nothing
  delivered): SelfPost 60 MB at rest, 123 MB with 20 SMTP sessions to port
  25 held open; rspamd 118 MB at rest, 153 MB scanning ten 100 KB messages
  at once, 232 MB one 25 MiB message, 424 MB three at once, 139 MB after.
  Caddy 10 MB, nginx 3 MB, Traefik 21 MB at rest (images 92/280/231 MB).
- The host column: SelfPost's peak, rspamd's for the case, and a stated
  300 MB allowance for the system and Docker (not measured on a fresh
  host). With the spam filter 768 MB when port-25 messages are small or
  rarely large, 1 GB for several 25 MiB at once; 512 MB is not enough
  (about 480 MB at rest with the allowance, +100 MB a large message).

 ## [Unreleased]
 
+### Documentation
+
+- **Machine requirements by what is switched on** (guide § Installation,
+  README § Requirements), measured on the test installation instead of the
+  old unmeasured "1 vCPU, 512 MB-1 GB, 8-10 GB": 512 MB of host memory for
+  outbound mail with or without port 25; with the spam filter 768 MB when
+  port-25 messages are kept small and 1 GB for several 25 MiB messages at
+  once (rspamd measured at 118 MB at rest, 232 MB on one 25 MiB message,
+  424 MB on three); the proxy containers' own; one vCPU. Building the image needs 1.5 GB of memory - a build held to 1 GB was
+  killed in the Go compiler - and about 3 GB of free disk. The send log
+  grows about 2-3 KB a message for its retention.
+
+## [2.16.0] - 2026-10-18
+
+The queues as the 2.0 mockups drew them: Outbound › Queue a table, Inbound ›
+Queue built. No migration; schema 14.
+
+### Added
+
+- **Inbound › Queue** (`/inbound/queue`, global role, with the inbound relay
+  on): mail accepted on port 25 that its upstream has not yet taken, a row
+  per recipient with the upstream's last reply - the screen `in-queue`, drawn
+  for 2.0 and not built until now. Help has its topic.
+
+### Changed
+
+- **Outbound › Queue is the table the mockup draws** instead of
+  `postqueue -p`'s text: a row per recipient, oldest first - queue id, when
+  it arrived, sender, recipient, and the last reply of the receiving server
+  or why no connection was made - with *Details* to the message in the
+  Outbound log when it has a row there. The box head counts the messages and
+  their size; past 200 recipients the oldest 200 are listed and a line says
+  how many wait. Read from `postqueue -j` (Postfix 3.10.13,
+  `src/postqueue/showq_json.c`: `message_size`, and a recipient's
+  `delay_reason` when it has one). A recipient of an inbound domain is on
+  Inbound › Queue instead.
+- **Overview's queue card** is *Queues*, "Both empty", "outbound and inbound"
+  while the inbound relay is on, as the mockup has it: Postfix keeps one queue
+  for both.
+- `TestUnbuiltScreensAreOnTheRoadmap`: a screen the guards let pass unbuilt
+  must be named in `docs/roadmap.md`. The two queues had been deferred on
+  2026-10-09 with no roadmap row and were forgotten; development.md says so.
+
+### Fixed
+
+Two gaps a comparison of every mockup with the panel found (the rest
+matches):
+
+- **Server › Users, the user form:** with *All outbound domains* (or *All
+  inbound domains*) ticked, that list's single domains are disabled, as the
+  mockup draws them - the server ignored them already, which the help line
+  says. panel.js does it; without scripts they stay clickable.
+- **Server › Backup, Import a domain:** "the domain's settings" links to
+  Outbound › Domains, where each domain's settings are, as the mockup's link
+  does.
+
+## [2.15.0] - 2026-10-18
+
+The two proposals the security audit left as product choices. Migration
+0014; schema 14.
+
+### Added
+
+- **Verified TLS to an inbound domain's upstream** (upstream-tls-verify; the
+  security audit's M7): a fourth choice beside Opportunistic, Required and
+  Off - Postfix's `secure` level, which also checks that the upstream's
+  certificate was issued by a trusted authority for its name. The upstream
+  is then given by name. Postfix's SMTP client now trusts Debian's
+  `ca-certificates`; mail to the recipients' MX is unchanged. Migration
+  0014 widens the stored TLS mode; schema 14.
+- **A DMARC record for the server's own name** (server-dmarc-hint; the
+  security audit's S3): Server › Settings › Notification mail gives
+  `v=DMARC1; p=reject` at `_dmarc.<hostname>` beside the DKIM and SPF
+  records, checks it, and Health's card shows it. Without one a receiver
+  does not refuse mail forged in the server's name, a false password-reset
+  message among it; `p=none` is shown as weak.
+
+## [2.14.5] - 2026-10-18
+
+A line less in the mail log. No migration; schema 13.
+
+### Fixed
+
+- **ETRN is discarded from the EHLO reply silently**: since `2.14.4` Postfix
+  logged "discarding EHLO keywords: ETRN" for every connection on every port
+  (seen on the test server after the rollout); `silent-discard` keeps the
+  discard and drops the line.
+
+## [2.14.4] - 2026-10-17
+
+The follow-ups of the security audit of 2026-10-17
+([docs/security-audit-2026-10-17.md](docs/security-audit-2026-10-17.md)),
+stages 0-6: its one high (A2), its seven mediums and the lows. No migration;
+schema 13. Read *Upgrading* below: the TLS key's group, and copy
+`antispam/` again where the sidecar runs.
+
+### Upgrading
+
+- **Give the TLS private key to group 10997** (audit I1): `chgrp 10997
+  certs/privkey.pem` - or certbot's `archive/<name>/privkey*.pem` - and the
+  same in whatever renews it. Group 10998, which the guide named until now,
+  has Postfix in it; the backup keeps working with either, but only 10997
+  keeps the key from Postfix's daemons.
+- **With the antispam sidecar, copy `antispam/` again** (audit S4): rspamd
+  4.2.2, and a third file, `antispam/rspamd/worker-proxy.inc`, that the
+  fragment now mounts; `docker compose ... up -d` recreates the sidecar.
+- **Behind Apache on the host, set `TRUSTED_PROXY_CIDR`** if it is not set
+  (audit A1): the guide's install step prints the gateway to put there; the
+  panel's log says so after the first requests when it is missing.
+
+### Security
+
+- **A stolen `global` session no longer takes a full backup** (security
+  audit 2026-10-17, A2, high): the user form set the signed-in user's own
+  password without the current one, which then passed the backup's password
+  check. Adding a user, setting a password, changing an e-mail or a role on
+  the user form, and deleting a user now ask for your own account password,
+  as a backup does, under the same limit on wrong guesses - which now
+  counts wrong passwords only.
+- **One stranger behind a shared proxy no longer locks everyone out of
+  signing in** (audit A1, A8, A9): sign-in counts failures per address and
+  username (a hundred per address alone), a right password no longer
+  counts, a link's page is limited per link, a reset request per address
+  and name, and an IPv6 client is one per /64. With every request coming
+  from one private address with `X-Forwarded-For` and `TRUSTED_PROXY_CIDR`
+  empty, the log says what to set. Refused sign-ins are logged.
+- **Reset links pause for a day after five** (audit A3): anyone who knew a
+  username could keep a live reset link arriving in that mailbox five times
+  an hour. After five in a day the owner is told once that further requests
+  are ignored for 24 hours.
+- **`/healthz` is not answered through the reverse proxy** (audit I6):
+  only a request with no `X-Forwarded-For` from loopback or a private
+  address gets the liveness answer - the container's own check, the host,
+  a monitor next to it; the internet gets `404`.
+- **Every container has a process ceiling** (audit I3): `pids_limit` 1024
+  for SelfPost, 256 for the proxies and rspamd, 64 for certbot.
+- **A save that changes no map no longer reloads Postfix, and DNS
+  re-checks are limited** (audit W6/M9): every application, upstream,
+  recipient or report-address save reloaded Postfix, and *Re-check DNS*
+  bypassed the cache without limit. Now only a changed file is written and
+  reloaded (Health's *Reload configuration* always re-reads), and a user
+  re-checks twenty times in 15 minutes.
+- **A domain import is bounded** (audit W4, W5, W8): a DKIM key over 4096
+  bits, more than 500 applications, and a domain named as the server
+  itself - whose key signs the panel's own mail - are refused.
+- **The build is pinned and checked** (audit I4, I5): GitHub Actions by
+  commit, certbot and Caddy by release; govulncheck on the source in CI and
+  on the image's binaries before a release is pushed; a weekly check says
+  when a Debian package the mail path runs on has moved, so that a patch
+  release follows.
+- **The signature covers `Content-Type`, `MIME-Version` and `Message-ID`**
+  when the message has them (audit M6), and a header line too long to be
+  delivered unbroken is named in the log as a body line is (M8).
+- **A session made under a longer `PANEL_SESSION_IDLE_DAYS` is cut to the
+  current window** at its next request (audit A10), not kept until its old
+  expiry.
+- **The antispam sidecar runs rspamd 4.2.2, hardened** (audit S4): from
+  3.11.1 (December 2024; the line between fixed a heap overflow, a
+  use-after-free on reload and parser crashes), with no Linux capability,
+  `no-new-privileges`, and only the milter on the compose network - the
+  scanner and the controller, whose default password is public, stay on the
+  sidecar's loopback. A third file, `antispam/rspamd/worker-proxy.inc`, is
+  mounted; copy it with the fragment.
+- **The TLS private key no longer has to be readable by Postfix** (audit
+  I1): the guide gave it to group 10998 for the panel's backup, and
+  `postfix` is in that group, so every Postfix daemon - an smtpd talking to
+  the internet included - could read it. A new group, `backupkey` (10997),
+  holds the panel alone; the guide, Help and the backup's refusal name it.
+
+- **A domain's rate limit is taken only by its own applications** (audit
+  M1): the level-2 domain limit was read from `MAIL FROM`, which reaches the
+  milter before Postfix holds it to the login, so a client that never
+  signed in, or another tenant's application, could use up a domain's
+  limit. It is now the signed-in application's domain.
+- **One accepted message is one Inbound › Log row per recipient** (audit
+  M3): a recipient repeated in RCPT TO, up to Postfix's thousand, was a row
+  each, and the journal milter's rows did not count toward the 10 000-row
+  cut between the six-hourly prunes. Repeats are one row, a message's rows
+  are written in one transaction, and both writers count toward the cut.
+- **A domain's custom DMARC report address may not be on the server's own
+  name** (audit W1): it opened a mailbox the whole internet could file
+  reports into, under any domain, or another domain's hosted one. Only the
+  hosted address of a domain that chose it is a mailbox now, and a report
+  must arrive at the address tagged with its domain.
+- **A domain's DMARC reports are deleted with it** (audit A5/W2): reports
+  belong to a domain by name, and a domain deleted and added again showed
+  its old reports to whoever it was assigned to then.
+- **The sender map is rebuilt one change at a time** (audit W3): two
+  application changes at once could leave the map without the newer one
+  until the next change.
+- **A stranger's recipient no longer writes an Inbound › Log row** (audit
+  M2): Postfix quotes a refused recipient in its reply with the quotes
+  removed, so `RCPT TO:<"; from=<x> to=<y> …"@domain>` spelled a second
+  sender and recipient there, and the parser took the first. It now takes
+  Postfix's own tail at the end of the line.
+- **The sender check keeps two `From:` and two `Sender:` lines** (audit M5),
+  not every one an application sends: the judgement needs no more, and a
+  hundred long lines were megabytes held per connection.
+- **A link's token stays out of the duplicate-cookie log line** (audit A4),
+  as it already did out of the origin check's.
+- **ETRN is refused and no longer offered** (audit S6): Postfix's default
+  let anyone on port 25 flush the queue toward an inbound domain's upstream.
+- **SECURITY.md names the 2.x line as the supported one** (audit X1); its
+  table still said 1.x.
+- **The entrypoint follows no link at the DMARC maps** (audit I2): the
+  three `dmarc_*` maps root creates at the start were missing from the list
+  of paths where a symbolic link is removed first.
+
+### Documentation
+
+- security.md says what the code does where it said more (audit A6, A7,
+  W7): a wrong method answers `405` before the role is looked at; the setup
+  token is made anew at the first request after it expired; two GETs make
+  the server's own DKIM key on first view. The README's local trial says
+  that the compose file is the hardened deployment.
+
+- **The upstream's "Required" TLS checks no certificate**, and the guide and
+  Help now say so (audit M7): it guards against a listener, not against one
+  who answers in the upstream's place.
+
+
+## [2.14.3] - 2026-10-17
+
+A tag beside a label. No migration; schema 13.
+
+### Fixed
+
+- **A tag beside a label no longer squeezes the field under it**: the
+  e-mail's "not confirmed" on Account made its label taller and left less
+  room above the field than Username has (the owner's phone).
+
+## [2.14.2] - 2026-10-17
+
+The last small items of the day. No migration; schema 13.
+
+### Added
+
+- **Health dials the inbound journal's socket** with the inbound relay on:
+  the milter that writes Inbound › Log was the one the panel did not check.
+  The send log's socket is named as the mockup names it, `journal-milter`.
+
+### Changed
+
+- **A DMARC report says which day it is**: its day stays the reporter's, in
+  UTC (owner, 2026-10-17: accepted as it is), and the report's page now says
+  so under its window; Settings and Help name it as the one exception to
+  the panel's zone. A daily report from midnight to midnight is one day, not
+  two.
+
+### Documentation
+
+- The guide's gaps from the docs audit: `/license` and `/server/components`,
+  DMARC pages' paths, `selfpost-backup -o`, `-i` and `-version`, the
+  Inbound log's retention field, `PANEL_COOKIE_SECURE`.
+
+## [2.14.1] - 2026-10-17
+
+Overview's head in the mockup's words. No migration; schema 13.
+
+### Changed
+
+- **Overview's head says it as the mockup does** (overview-head): "Mail is
+  flowing. One thing needs attention." - or "Nothing needs attention", or
+  "Mail may not be flowing" when a check fails - and under it each check
+  that is not fine with its value ("TLS certificate: expires in 12 days.").
+
+## [2.14.0] - 2026-10-17
+
+Password reset by e-mail, to a confirmed address. Migration 0013; schema 13.
+
+### Added
+
+- **Password reset by e-mail** (password-reset): *Forgot your password?* on
+  the sign-in page sends a one-time link, for 30 minutes, to the account's
+  e-mail - once that address has been confirmed by a link sent to it. A new
+  address is sent its confirmation link when it is saved (Account, or the
+  user form); Account shows whether it is confirmed and can send the link
+  again. Notifications go to the address confirmed or not. Setting a new
+  password from a link signs every session of the account out. Migration
+  0013; schema 13.
+
+### Changed
+
+- **Changing your e-mail on Account asks for your password**, as changing
+  the password does: the address is where a reset link goes.
+
+## [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`.

It proves the path from this server - TLS, its address's reputation, the SPF and DKIM records of its name - not your domains', which only mail from an application does. 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>

The PTR record is set at your hosting provider, not in your DNS zone. <em>Greeting</em> is the line Postfix opens every connection with, <code>220</code> and its banner; it must name the hostname too - a receiver compares it with the name it looked up - and a container id or <code>localhost</code> there is a warning.</p></div>

Publish all three exactly as shown; merge SPF into an existing record rather than adding a second one. A domain's status is the worst of its three records, and results are cached for a few minutes, so use Re-check DNS after publishing. A record DNS already holds as shown is folded to its name and status; Show values opens it to copy them again. The SPF check is shallow: it looks for this server's address in the record itself and does not follow <code>include:</code> or <code>redirect=</code>, so a record that relies on them is reported as a warning, not a failure. <code>p=none</code> does not affect delivery; tighten to <code>quarantine</code>, then <code>reject</code>, once the reports look clean. A domain's report address is set in its Domain settings.</p></div>

The password is shown once at creation or regeneration and is not stored in readable form.</p></div>
+          <div class="sp-help-topic" id="apps"><h3>Applications</h3><p>An application is one SASL login, unique across all domains. It may send as any address of its domain or only as listed addresses, and, with a list of client IPs set, only from those addresses. The password is shown once, at creation or regeneration, and the panel does not show it again; the server keeps it, so a domain export can carry it.</p></div>
           <div class="sp-help-topic" id="sender-check"><h3>Sender check</h3><p>An application sends only as itself, and that holds for every sender a message names. The envelope sender is held against the login by Postfix. The <code>From:</code> line, the one a mail program shows and the one DMARC holds the DKIM signature to, is held against it by the panel, under the same rule: an application set to any address of its domain may write any address of that domain, and one with a list of addresses only those. A message with any other <code>From:</code> - another of your domains, the server's own name, an address somewhere else, or none at all - is refused for good with <code>550 5.7.1</code>. The line must hold one address, read as a mail program reads it: what a display name around it says is not judged, and a line holding more than one address is refused. A <code>Sender:</code> line, which a mail program shows beside <code>From:</code> as "on behalf of", is held to the same rule when the message has one. A system that writes for people outside your domains writes its own address in <code>From:</code> with the person's name, and the person's address in <code>Reply-To:</code>: their domain in <code>From:</code> would fail DMARC at the receiver anyway. It is a rejected row of the Outbound log, and its page says which address was refused. This is what keeps one application from sending, under this server's signature, as another domain or another application.<br><br>The check is strict. While the panel does not answer, Postfix does not accept mail unchecked: it replies with a temporary error and the application sends again later. Server › Health counts what that costs: for how long the panel did not answer while Postfix itself was running; how many connections Postfix turned away because of it - it refuses from the connection on, before a message is offered, so a client that tries three times is three and a monitor that only connects is one; and how many messages were refused with a temporary error in the middle, when the panel stopped answering after a message had begun. A time marked ≈ includes a start at which supervisord could not say since when Postfix was running: the time since the panel's last sign of life is counted, which may be more than Postfix was up. The card warns when a connection was turned away or a message refused in the last 24 hours. If the numbers stay at nothing, the check is where it should be; if they do not, it belongs in a process of its own.</p></div>
           <div class="sp-help-topic" id="limits"><h3>Rate limits</h3><p>Level 1 is a per-IP ceiling set in <code>.env</code>. Level 2 is optional, per domain and per application, entered by hand or computed from the last 30 days of sending, and can never exceed level 1. An application's own limit replaces its domain's.</p></div>
-          <div class="sp-help-topic" id="log"><h3>Outbound log</h3><p>One row per message and recipient, with the status Postfix last reported: queued (accepted, nothing reported yet), sent (the receiving server took it; what the mailbox does next is not reported back), deferred (not taken yet, Postfix tries again), bounced (failed for good, or the queue lifetime ran out; or closed by the panel when Postfix no longer held the message and <code>mail.log</code> never said what became of it) and rejected (refused before queueing, so it never reached the queue: under a level-2 rate limit, from a client address the application does not allow, or for a <code>From:</code> or <code>Sender:</code> line that is not the application's - the message's page says which). A message's page lists these steps and the lines Postfix wrote about it in <code>mail.log</code>, found by queue id - and for a message refused before it had one, Postfix's one line about the refusal. The lines are kept with the row: they stay on the page after that file has rotated, for as long as the row does. A message accepted before version 2.2.0 shows them only while they are still in the current file. Rows are deleted after the retention set in Server › Settings, 90 days by default, and their lines with them. A domain administrator sees only the rows of their own domains.</p></div>
-          <div class="sp-help-topic" id="queue"><h3>Queue and retries</h3><p>The page lists, as <code>postqueue -p</code> prints it, the messages Postfix has accepted and not yet delivered: mail being sent right now and mail deferred for a later attempt. Only the global role can open it, and it only shows; nothing here deletes or forces a message. A deferred message is tried again after the first retry delay, then at gaps that double up to a cap, until the receiving server takes it or the queue lifetime runs out and it bounces; there is no attempt counter, and the box on the page shows this server's values. A queue that keeps growing means a receiver is refusing or not answering: open the message from the Outbound log to read the reason Postfix logged.</p></div>
-          <div class="sp-help-topic" id="dmarc"><h3>DMARC reports</h3><p>An aggregate report is the summary a receiving provider sends, usually daily, to the <code>rua=</code> address of your DMARC record: which servers sent mail as your domain and whether SPF or DKIM passed for it. 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>

Only the global role can open it, and it only shows; nothing here deletes or forces a message, and Details opens the message in the Outbound log. A deferred message is tried again after the first retry delay, then at gaps that double up to a cap, until the receiving server takes it or the queue lifetime runs out and it bounces; there is no attempt counter, and the box on the page shows this server's values.

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).

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="inbound"><h3>Backup-MX and forwarding</h3><p>An optional backup-MX or forwarder, switched on in the server's <code>.env</code>; the Inbound menu exists only then. Postfix accepts mail on port 25 for the listed domains only and hands each message on to that domain's upstream; there are no mailboxes. For each domain publish the MX record its page shows, and keep a primary MX the domain already has if this is a backup. The MX tag is green when at least one MX of the domain points at this server, and a domain accepts no mail until an upstream is saved on its page. Adding and deleting domains is for the global role.</p></div>
-          <div class="sp-help-topic" id="upstream"><h3>Upstream</h3><p>The upstream is the server that actually holds the mailboxes. Give its host and port — used exactly as written, with no MX lookup — and choose the TLS for the hop to it: Opportunistic uses TLS when the upstream offers it and otherwise sends in the clear; Required sends only over TLS, and the mail waits in the queue while the upstream does not offer it or the TLS handshake fails - an upstream that answers STARTTLS with a permanent error bounces it; Off never uses TLS. While the upstream does not answer, Postfix keeps the mail and retries as for any other mail.</p></div>
+          <div class="sp-help-topic" id="upstream"><h3>Upstream</h3><p>The upstream is the server that actually holds the mailboxes. Give its host and port — used exactly as written, with no MX lookup — and choose the TLS for the hop to it: Opportunistic uses TLS when the upstream offers it and otherwise sends in the clear; Required sends only over TLS, and the mail waits in the queue while the upstream does not offer it or the TLS handshake fails - an upstream that answers STARTTLS with a permanent error bounces it. Neither checks the upstream's certificate: TLS here keeps the mail from whoever only listens on the way, not from one who answers in the upstream's place. Verified is Required with that check too: the upstream's certificate has to be issued by a trusted authority for the host given here, so the host is given by name, not by address, and the mail waits in the queue while the check fails - a certificate for another name, or one the upstream signed itself, included. Off never uses TLS. While the upstream does not answer, Postfix keeps the mail and retries as for any other mail.</p></div>
           <div class="sp-help-topic" id="recipients"><h3>Valid recipients</h3><p>Choose whom this domain accepts. Listed addresses only: the relay accepts exactly the addresses you list, one per line or comma-separated, and refuses any other while the sender is still connected, so it never has to send a bounce for them. Any recipient: everything at the domain is accepted and passed on, and an address the upstream then rejects comes back as a bounce from this server to a sender who is often forged — backscatter. Prefer a list, and keep it in step with the mailboxes upstream.</p></div>
           <div class="sp-help-topic" id="filter"><h3>Spam filter</h3><p>The spam filter belongs to the server, not to a domain. The server's administrator attaches it in the server's <code>.env</code>, and from then on every inbound domain is screened by it before mail is handed on; the box shows on or off and has nothing to switch. Off means mail goes to the upstream unfiltered. While the filter is down, mail is either accepted unfiltered (the default) or refused with a temporary error, so the sending server tries again later, as the server's setting says; the box states which.</p></div>
           <div class="sp-help-topic" id="inbound-log"><h3>Inbound log</h3><p>One row per recipient of a message offered on port 25 for an inbound domain, with what was decided: <span class="tag is-success is-light">accept</span> — taken for the upstream; <span class="tag is-danger is-light">reject</span> — refused for good; <span class="tag is-warning is-light">tempfail</span> — the sender was asked to come back later; <span class="tag is-primary is-light">quarantine</span> — held by the filter. <em>Why</em> names who decided. <code>rspamd</code> is the spam filter, with its action, the score against the reject threshold and the heaviest symbols; <code>postfix</code> is the relay's own rule — an unknown recipient, a sender domain that does not exist — with its reply; <code>selfpost</code> means nobody judged the message: it was relayed with no filter attached. <em>Upstream</em> says what became of an accepted message: <span class="tag is-light">queued</span> — not tried yet; <span class="tag is-primary is-light">held</span> — held in the queue by the filter, not tried until it is released; <span class="tag is-success is-light">sent</span> — the upstream took it; <span class="tag is-warning is-light">deferred</span> — the upstream put it off or could not be reached, and Postfix tries again; <span class="tag is-danger is-light">bounced</span> — the upstream refused it, or it waited in the queue too long, and the sender was sent a bounce, if it had a return address. It opens the last reply and the host that gave it. A refused message has no upstream result, and neither has a row logged before 2.10.0.<br><br>Accepted mail is recorded as it passes; refused mail is read from <code>mail.log</code>, so its row has no subject, and a message refused after its text was sent is one row however many recipients it had. A refusal to relay for a domain that is not an inbound one is every scanner on the internet and is not recorded. Rows are kept for the number of days set in Settings, and never more than 10 000.</p></div>
+          <div class="sp-help-topic" id="inbound-queue"><h3>Inbound queue</h3><p>Mail accepted on port 25 and not yet taken by its upstream, one row per recipient, with the upstream's last reply or why it could not be reached. It is the same Postfix queue as Outbound › Queue, split by the recipient's domain, and retried the same way; an upstream that refuses or does not answer is what makes it grow. Only the global role can open it, and it only shows.</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>

Both it and a domain's export ask for your account password - the one you sign in with - at every download, so a session left open is not enough to take them; wrong guesses count against the same limit as a password change. 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. To keep the queue, stop the container and archive the project directory instead. The private key in <code>certs/</code> has to be readable by the panel: give it to group 10998 on the host (<code>chgrp 10998</code>, <code>chmod 640</code>). 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. The reverse-proxy configuration and <code>mail.log</code> are not included. One domain moves on its own: Export domain on its settings page writes a <code>.json</code> (or encrypted <code>.spde</code>) with its DKIM key and its applications' passwords, and Import a domain here reads it into another instance, so the published DNS needs no change.</p></div>

Domain reaches only the domains assigned to it, outbound and inbound separately (the same name on both lists is two assignments); <em>All</em> includes domains added later, and a domain user needs at least one domain or <em>All</em> on either list.

It proves the path from this server - TLS, its address's reputation, the SPF and DKIM records of its name - not your domains', which only mail from an application does. 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>.

Publish all three exactly as shown; merge SPF into an existing record rather than adding a second one. A domain's status is the worst of its three records, and results are cached for a few minutes, so use Re-check DNS after publishing. A record DNS already holds as shown is folded to its name and status; Show values opens it to copy them again. The SPF check is shallow: it looks for this server's address in the record itself and does not follow <code>include:</code> or <code>redirect=</code>, so a record that relies on them is reported as a warning, not a failure. <code>p=none</code> does not affect delivery; tighten to <code>quarantine</code>, then <code>reject</code>, once the reports look clean.

+          <div class="sp-help-topic" id="apps"><h3>Applications</h3><p>An application is one SASL login, unique across all domains. It may send as any address of its domain or only as listed addresses, and, with a list of client IPs set, only from those addresses. The password is shown once, at creation or regeneration, and the panel does not show it again; the server keeps it, so a domain export can carry it.</p></div>
           <div class="sp-help-topic" id="sender-check"><h3>Sender check</h3><p>An application sends only as itself, and that holds for every sender a message names. The envelope sender is held against the login by Postfix. The <code>From:</code> line, the one a mail program shows and the one DMARC holds the DKIM signature to, is held against it by the panel, under the same rule: an application set to any address of its domain may write any address of that domain, and one with a list of addresses only those. A message with any other <code>From:</code> - another of your domains, the server's own name, an address somewhere else, or none at all - is refused for good with <code>550 5.7.1</code>. The line must hold one address, read as a mail program reads it: what a display name around it says is not judged, and a line holding more than one address is refused. A <code>Sender:</code> line, which a mail program shows beside <code>From:</code> as "on behalf of", is held to the same rule when the message has one. A system that writes for people outside your domains writes its own address in <code>From:</code> with the person's name, and the person's address in <code>Reply-To:</code>: their domain in <code>From:</code> would fail DMARC at the receiver anyway. It is a rejected row of the Outbound log, and its page says which address was refused. This is what keeps one application from sending, under this server's signature, as another domain or another application.<br><br>The check is strict. While the panel does not answer, Postfix does not accept mail unchecked: it replies with a temporary error and the application sends again later. Server › Health counts what that costs: for how long the panel did not answer while Postfix itself was running; how many connections Postfix turned away because of it - it refuses from the connection on, before a message is offered, so a client that tries three times is three and a monitor that only connects is one; and how many messages were refused with a temporary error in the middle, when the panel stopped answering after a message had begun. A time marked ≈ includes a start at which supervisord could not say since when Postfix was running: the time since the panel's last sign of life is counted, which may be more than Postfix was up. The card warns when a connection was turned away or a message refused in the last 24 hours. If the numbers stay at nothing, the check is where it should be; if they do not, it belongs in a process of its own.</p></div>
           <div class="sp-help-topic" id="limits"><h3>Rate limits</h3><p>Level 1 is a per-IP ceiling set in <code>.env</code>. Level 2 is optional, per domain and per application, entered by hand or computed from the last 30 days of sending, and can never exceed level 1. An application's own limit replaces its domain's.</p></div>
-          <div class="sp-help-topic" id="log"><h3>Outbound log</h3><p>One row per message and recipient, with the status Postfix last reported: queued (accepted, nothing reported yet), sent (the receiving server took it; what the mailbox does next is not reported back), deferred (not taken yet, Postfix tries again), bounced (failed for good, or the queue lifetime ran out; or closed by the panel when Postfix no longer held the message and <code>mail.log</code> never said what became of it) and rejected (refused before queueing, so it never reached the queue: under a level-2 rate limit, from a client address the application does not allow, or for a <code>From:</code> or <code>Sender:</code> line that is not the application's - the message's page says which). A message's page lists these steps and the lines Postfix wrote about it in <code>mail.log</code>, found by queue id - and for a message refused before it had one, Postfix's one line about the refusal. The lines are kept with the row: they stay on the page after that file has rotated, for as long as the row does. A message accepted before version 2.2.0 shows them only while they are still in the current file. Rows are deleted after the retention set in Server › Settings, 90 days by default, and their lines with them. A domain administrator sees only the rows of their own domains.</p></div>
-          <div class="sp-help-topic" id="queue"><h3>Queue and retries</h3><p>The page lists, as <code>postqueue -p</code> prints it, the messages Postfix has accepted and not yet delivered: mail being sent right now and mail deferred for a later attempt. Only the global role can open it, and it only shows; nothing here deletes or forces a message. A deferred message is tried again after the first retry delay, then at gaps that double up to a cap, until the receiving server takes it or the queue lifetime runs out and it bounces; there is no attempt counter, and the box on the page shows this server's values. A queue that keeps growing means a receiver is refusing or not answering: open the message from the Outbound log to read the reason Postfix logged.</p></div>
-          <div class="sp-help-topic" id="dmarc"><h3>DMARC reports</h3><p>An aggregate report is the summary a receiving provider sends, usually daily, to the <code>rua=</code> address of your DMARC record: which servers sent mail as your domain and whether SPF or DKIM passed for it. 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>

A deferred message is tried again after the first retry delay, then at gaps that double up to a cap, until the receiving server takes it or the queue lifetime runs out and it bounces; there is no attempt counter, and the box on the page shows this server's values.

+          <div class="sp-help-topic" id="dmarc"><h3>DMARC reports</h3><p>An aggregate report is the summary a receiving provider sends, usually daily, to the <code>rua=</code> address of your DMARC record - its day is the reporter's, counted in UTC, and that is the day the lists and a report's title name, while the report's page gives its window in this panel's zone: which servers sent mail as your domain and whether SPF or DKIM passed for it. 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="inbound"><h3>Backup-MX and forwarding</h3><p>An optional backup-MX or forwarder, switched on in the server's <code>.env</code>; the Inbound menu exists only then. Postfix accepts mail on port 25 for the listed domains only and hands each message on to that domain's upstream; there are no mailboxes. For each domain publish the MX record its page shows, and keep a primary MX the domain already has if this is a backup. The MX tag is green when at least one MX of the domain points at this server, and a domain accepts no mail until an upstream is saved on its page. Adding and deleting domains is for the global role.</p></div>
-          <div class="sp-help-topic" id="upstream"><h3>Upstream</h3><p>The upstream is the server that actually holds the mailboxes. Give its host and port — used exactly as written, with no MX lookup — and choose the TLS for the hop to it: Opportunistic uses TLS when the upstream offers it and otherwise sends in the clear; Required sends only over TLS, and the mail waits in the queue while the upstream does not offer it or the TLS handshake fails - an upstream that answers STARTTLS with a permanent error bounces it; Off never uses TLS. While the upstream does not answer, Postfix keeps the mail and retries as for any other mail.</p></div>
+          <div class="sp-help-topic" id="upstream"><h3>Upstream</h3><p>The upstream is the server that actually holds the mailboxes. Give its host and port — used exactly as written, with no MX lookup — and choose the TLS for the hop to it: Opportunistic uses TLS when the upstream offers it and otherwise sends in the clear; Required sends only over TLS, and the mail waits in the queue while the upstream does not offer it or the TLS handshake fails - an upstream that answers STARTTLS with a permanent error bounces it. Neither checks the upstream's certificate: TLS here keeps the mail from whoever only listens on the way, not from one who answers in the upstream's place. Verified is Required with that check too: the upstream's certificate has to be issued by a trusted authority for the host given here, so the host is given by name, not by address, and the mail waits in the queue while the check fails - a certificate for another name, or one the upstream signed itself, included. Off never uses TLS. While the upstream does not answer, Postfix keeps the mail and retries as for any other mail.</p></div>
           <div class="sp-help-topic" id="recipients"><h3>Valid recipients</h3><p>Choose whom this domain accepts. Listed addresses only: the relay accepts exactly the addresses you list, one per line or comma-separated, and refuses any other while the sender is still connected, so it never has to send a bounce for them. Any recipient: everything at the domain is accepted and passed on, and an address the upstream then rejects comes back as a bounce from this server to a sender who is often forged — backscatter. Prefer a list, and keep it in step with the mailboxes upstream.</p></div>
           <div class="sp-help-topic" id="filter"><h3>Spam filter</h3><p>The spam filter belongs to the server, not to a domain. The server's administrator attaches it in the server's <code>.env</code>, and from then on every inbound domain is screened by it before mail is handed on; the box shows on or off and has nothing to switch. Off means mail goes to the upstream unfiltered. While the filter is down, mail is either accepted unfiltered (the default) or refused with a temporary error, so the sending server tries again later, as the server's setting says; the box states which.</p></div>
           <div class="sp-help-topic" id="inbound-log"><h3>Inbound log</h3><p>One row per recipient of a message offered on port 25 for an inbound domain, with what was decided: <span class="tag is-success is-light">accept</span> — taken for the upstream; <span class="tag is-danger is-light">reject</span> — refused for good; <span class="tag is-warning is-light">tempfail</span> — the sender was asked to come back later; <span class="tag is-primary is-light">quarantine</span> — held by the filter. <em>Why</em> names who decided. <code>rspamd</code> is the spam filter, with its action, the score against the reject threshold and the heaviest symbols; <code>postfix</code> is the relay's own rule — an unknown recipient, a sender domain that does not exist — with its reply; <code>selfpost</code> means nobody judged the message: it was relayed with no filter attached. <em>Upstream</em> says what became of an accepted message: <span class="tag is-light">queued</span> — not tried yet; <span class="tag is-primary is-light">held</span> — held in the queue by the filter, not tried until it is released; <span class="tag is-success is-light">sent</span> — the upstream took it; <span class="tag is-warning is-light">deferred</span> — the upstream put it off or could not be reached, and Postfix tries again; <span class="tag is-danger is-light">bounced</span> — the upstream refused it, or it waited in the queue too long, and the sender was sent a bounce, if it had a return address. It opens the last reply and the host that gave it. A refused message has no upstream result, and neither has a row logged before 2.10.0.<br><br>Accepted mail is recorded as it passes; refused mail is read from <code>mail.log</code>, so its row has no subject, and a message refused after its text was sent is one row however many recipients it had. A refusal to relay for a domain that is not an inbound one is every scanner on the internet and is not recorded. Rows are kept for the number of days set in Settings, and never more than 10 000.</p></div>
+          <div class="sp-help-topic" id="inbound-queue"><h3>Inbound queue</h3><p>Mail accepted on port 25 and not yet taken by its upstream, one row per recipient, with the upstream's last reply or why it could not be reached. It is the same Postfix queue as Outbound › Queue, split by the recipient's domain, and retried the same way; an upstream that refuses or does not answer is what makes it grow. Only the global role can open it, and it only shows.</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. To keep the queue, stop the container and archive the project directory instead. The private key in <code>certs/</code> has to be readable by the panel: give it to group 10998 on the host (<code>chgrp 10998</code>, <code>chmod 640</code>). 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. The reverse-proxy configuration and <code>mail.log</code> are not included. One domain moves on its own: Export domain on its settings page writes a <code>.json</code> (or encrypted <code>.spde</code>) with its DKIM key and its applications' passwords, and Import a domain here reads it into another instance, so the published DNS needs no change.</p></div>
