The owner's decision of 2026-10-10, as the plan has it (Who sees what:
for the global administrator the filter's socket is one of the milter
sockets on Health and Overview). Written by Sonnet, reviewed by Opus.
- internal/health: CheckMilter probes an address in Postfix's two
forms. unix:/path is the existing stat; inet:host:port is a TCP
dial with a 1 s cap, closed at once, nothing written. An address in
neither form is reported as not checkable, never as fine. Details
are plain sentences ("No answer from antispam:11332 within 1 s.",
"Connection to ... refused.", "The name ... could not be
resolved.") and never the Go error text.
- Health: with the filter on, a third row "Spam filter - inbound"
with the configured address; it counts in the socket status and in
Overview's Milter sockets card. A filter that does not answer is an
error when INBOUND_ANTISPAM_MILTER_ACTION is tempfail (inbound mail
is deferred) and a warning otherwise (mail goes through
unfiltered), and the row says which. With the filter off nothing
changes.
- Both pages are global-only; a test checks a domain administrator
never receives the address.
The dial runs with the other checks on every request and poll of
Overview and Health (5 s active, 30 s idle, none while the tab is
hidden): a dead filter costs a poll at most 1 s, and a live one sees a
connect-and-close at that rhythm per open tab.
Not changed: fixtures and screenshots (the mockup draws two sockets),
help texts. The CHANGELOG line comes with the documentation step, which
is editing that file now.

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

[1.2.1]
Panel refinements after 1.2.0: navigation icons, status-badge centreing, drill-down back-link placement, and safeguards for the sole global administrator. Upgrading is a tag bump; no migration.
Fixed:
- panel: status badge text sat low in the box (and below the heading or label
- panel: the **Users** navigation icon was two full silhouettes with staggered
- panel: the **Settings** navigation icon was a sun-with-rays (circle plus
- panel: the user create/edit form placed «Back to users» at the bottom of the
Changed:
- panel: the user edit form disables role change and delete for the only global
- panel: the user create/edit form hides **Assigned domains** when the role is
- panel: **Settings** shows panel credentials and DMARC aggregate reports side
[1.2.2]
Status page layout after 1.2.1: paired cards in a wide column, denser machine and check copy, and a user-form checkbox fix. Upgrading is a tag bump; no migration.
Changed:
- panel: **Status** is wide again so paired cards fill the column. Layout:
Fixed:
- panel: cards inside `.split` used `margin: 0 auto`, which in a CSS grid
- panel: on the user create/edit form, **Assigned domains** checkboxes stacked
[1.2.3]
Domain detail layout and panel polish after 1.2.2. Upgrading is a tag bump; no migration.
Changed:
- panel: the domain detail page is wide with paired cards (DKIM+SPF ‖ DMARC;
- panel: Domains list — **Add domain** sits beside the domain field; the
- panel: page URLs, browser titles, and headings are aligned — **Settings** is
Fixed:
- image: `mail.log` rotation no longer silently stops when the build context
[1.2.4]
Level-2 rate-limit semantics inverted after 1.2.3, plus a small DNS field height fix. Upgrading is a tag bump; no migration.
Changed:
- rate limiting (level 2): domain ceilings apply to every client IP (no IP
Fixed:
- panel: on the domain DNS status grid, the Type (TXT) field height matches
[1.2.5]
Rate-limit form polish after 1.2.4. Upgrading is a tag bump; no migration.
Changed:
- panel: rate-limit forms refined — level-1 backstop as muted copy on the
