Security audit 2026-10-17, findings W6/M9 (low), stage 4. Every
application, upstream, recipient or report-address save reloaded Postfix
through supervisord, and POST .../dns-recheck bypassed the five-minute
cache for up to ~14 resolver queries - both at whatever rate an
authenticated user pressed.
- writeChanged: each generated map is written only when its content
differs from the file on disk, and Postfix is reloaded only when one was
(sender map, inbound maps, DMARC maps). Health's Reload configuration
ends with an explicit reload (app.Service.ReloadPostfix, SenderMaps
gains Reload), so it still re-reads whatever is on disk. No debounce:
with unchanged saves gone, a burst is real changes Postfix must see.
- auth.AllowDNSRecheck: twenty forced re-checks in 15 minutes per user;
past that the outbound, inbound and settings re-check show the cached
result without the "re-checked" flash, and the log says why.
Tests: TestARebuildThatChangesNothingDoesNotReload,
TestDNSRechecksArePerUser; the fakes gain Reload. Docs: guide § Overview
and Health; CHANGELOG; plan.

Review pass over `1.4.0`…`1.9.1`: port 25 no longer shares the submission milter chain, DMARC reports are validated before they are stored, and the auto rate limit is correct for a non-default level-1 window. Schema migration `0010` (index only). Upgrading is a tag bump.
