from-header-binding: the sender check, what it costs, its pages; guide, architecture, security
test / test (push) Canceled after 0s
A message's From: line is held against the application that sends it, under the rule Postfix holds the envelope sender to. OpenDKIM chooses the key by that line, so until now an application could have mail signed as another domain of the server or as the server itself. The check (internal/milter/sender.go) - A role of the panel on a socket of its own (SENDER_CHECK_SOCKET), first in smtpd_milters and strict: default_action=tempfail. The journal milter keeps its socket and stays fail-open. postfix-wrapper waits for the new socket. - It reads no database: what an application may send as comes from Postfix's own sender_login_maps, what the server signs for from OpenDKIM's SigningTable. Both are read again when they change; one that cannot be read defers mail. - One From: field, one address, allowed by the envelope's lookup; then no other name of the SigningTable may appear anywhere in the raw line. Refused: 550 5.7.1 naming the line, reduced to printable ASCII. - A refusal is a send-log row with reason "from" and the header address (migration 0006), written by another goroutine and not waited for. The journal's refusals record their reason too (limit, client), and the notifier takes only a limit's. What it costs (docs/plans/from-header-binding.md, Statistics) - The role marks itself alive every 2 s; at start the gap since the mark is downtime, counted from Postfix's start if later and not at all when supervisord says Postfix is not running. - The log tailer counts the connections Postfix turned away: a warning that names the socket, then milter-reject "Service unavailable" from the same smtpd. Seen on the stand: the client is refused from CONNECT on and leaves at AUTH (454), so no MAIL line is ever written. - sender_check_days, a row per UTC day, kept a year. Pages - Health: the card "Sender check", the socket's row, and the cards layout - boxes numbered by importance in two stacks read in rows; the left stack polls, the three readings of the right one are swapped in by id. - Outbound log: a refused row says why in its tag (wrong From, wrong client, rate-limited); the message's page shows the From: line and what the application may send as. - Help: topic "Sender check", word for word the mockup's. Found by the stand, fixed here: the names for the second look came from the sender bindings, and a domain with a key and no application yet was not among them. e2e: negative_journal_milter_fail_open is gone - it proved that mail passes with the panel down, which is no longer so. In its place sender_check_holds_the_from_line (another domain's From:, the hostname's, a stranger's, an address off the list, another sender in the display name - refused; own addresses - delivered) and panel_down_defers_mail (4xx with the panel stopped, the container alive, mail again after, downtime and one deferred message on Health, the card warning). Test server, this tree before the last cosmetic edits (a fixture row, a fact's size, docs): go vet ok, go test 23 packages ok, make e2e ok (337 s). Locally after them: internal/web/view ok.

delivery-log-storage: a message's page reads its stored lines
The Delivery log box on a message's page was filled by searching the current
mail.log on every view; that file is rotated daily, so the box was empty for
anything not sent today. deliveryLog now asks the store for the row's lines -
its queue id, dated within the row's queue lifetime plus a day
(RetryPolicy.LongestLifetime) - and shows the latest 200, oldest first.
When nothing is stored the page still searches the current file, which is
what shows a message accepted before 2.2.0. When that finds nothing either,
the note no longer blames rotation for the ordinary case: it says lines are
kept with the row since 2.2.0. The Outbound log help topic in help.go follows
the mockup changed in

panel-redesign: Help with seventeen topics; every box links to its own
Follows the design commit before it. Written by Sonnet, reviewed by
Opus.
- view/help.go, templates/help.html: the mockup's topics, texts, ids
and menu. The page shows the groups the reader's menu shows:
Overview and Server for the global role, Outbound and Inbound by
reach (Inbound only with the feature on), Account for everyone;
boxes are numbered as shown.
- Box.Help set on the boxes the mockups mark; the inbound MX box has
its link again.
- TestEveryHelpLinkLandsOnATopic also fails on a topic that no page
links to, unless it is listed as menu-only (account) - and on a
stale exception.
Known until the change that follows: the dns, dmarc and account topics
describe the three-choice report address, which the code does not have
yet; Account's DMARC box still links to #dns.
Not verified by running: three sentences rest on Postfix behaviour
(delivery is deferred when a required TLS session cannot be made; a
milter with default_action=tempfail answers 4xx; with "any recipient"
an address the upstream refuses comes back as a bounce).
Evidence
- docs/assets/panel-redesign/evidence/help.png (1440x3600) and
in-domain.png: headless Edge, real templates served locally with
their fixtures - NOT from the container.
- go test -count=1 ./internal/web/... ./cmd/panel: ok (six packages).

panel-redesign: Outbound log, message and the DMARC report pages on the kit
Stage 2, step 4. Written by Sonnet, reviewed by Opus.
- Five pages named after their mockups: out-log, out-message, dmarc,
dmarc-domain, dmarc-report, with typed page data
(view/outbound_log.go, dmarc.go), fixtures and tests. The engine
pages deliveries and delivery are gone with their templates; the
three DMARC templates are written anew. All five old names are off
legacy_pages.txt.
- The log polls its table (GET /outbound/log/fragment, as before); the
page count in the box foot follows out of band, and the filter in
the head is no longer swapped away while it is being chosen.
- Handlers pass typed data; routes, query parameters, filters, paging
and authorization are unchanged.
- Kit: Foot.ID / Foot.OOB (attributes only, as on Head) and Fact.Small,
the mockup's "sp-mono sp-small" value, for a report id and an rua
that wrapped mid-word in their column.
- test/e2e status scrapers match the new tag markup. Not run: no
Docker here.
Fixed on the way
- The DMARC domain page read a field its source rows do not have and
answered 500 as soon as the domain had a source. It builds the rows
from the store's rollup now, with a test.
Differences from the mockups, for the owner:
- the log has no Status filter (the store filters by domain and
application only); a refused message is "rejected", a neutral tag as
the mockup's "rate-limited" is;
- the message history keeps the panel's own wording with full dates and
has no "accepted from <IP>" step - the client address is not stored;
- dmarc: before the first report the box says "None yet" with what to
check; a quiet mailbox is an amber "quiet" tag;
- dmarc-domain: the stamp is pass / (pass + fail) rounded down, amber
on any failure, red when nothing passed, absent without mail;
- dmarc-report: the title has no year; "this relay" marks record rows
as well as sources.
Known and left as it is (not introduced here): the DMARC hub answers 404
to a domain administrator while the menu shows the entry and the plan
gives that role the reports of its own domains. Opening it needs the
report list to refuse an empty domain filter first - for the stage-3
security review.
Evidence
- docs/assets/panel-redesign/evidence/out-log.png, out-message.png,
dmarc.png, dmarc-domain.png, dmarc-report.png: 1440 px wide, headless
Edge, real templates served locally with their fixtures - NOT from
the container (no Docker on this machine).
- panel/audit.js on the five pages at 1440 and 1280: 784 texts checked,
problems: [].
- Polling of the log was exercised in a browser against a local
fixture server with document.hidden overridden: four polls, one
table and one foot after each, the filter untouched.
- go test -count=1 ./internal/web/... ./cmd/panel
ok internal/web
ok internal/web/auth
ok internal/web/handlers
