mix 7ef7f75246 release: 1.9.2: Review pass: port-25 milters, DMARC validation, rate-limit fix
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.
Added:
  - SQLite migration `0010_send_log_app_login_index.sql` —
  - DMARC aggregate reports are accepted as **zip** as well as gzip or plain XML
  - e2e: `checkPort25ConfigCombinations` regenerates the Postfix configuration
Changed:
  - README hero line and a **Positioning** block in `docs/product.md` record the
Fixed:
  - The setup account's password is hashed at bcrypt cost `12` like every other
  - Login/setup rate limiter: protecting blocked buckets from eviction is now
  - `postqueue -p` output is bounded to 4 MiB (the timeout alone left the size of
  - [schema-migrations.md](docs/schema-migrations.md): the schema section was
  - postqueue reader is now time-bounded: `postqueue -p` runs under a 5-second
  … (11 more in CHANGELOG)
Changed:
  - [roadmap.md](docs/roadmap.md) now carries everything the 2026-08-19 code
  - Extracted `internal/configsafe` — the empty-value and forbidden-character
  - Build, deploy and migration comments no longer cite the archived
  - Dropped the `parseDomainRateLimitForm` / `parseAppRateLimitForm` pass-through
  - Extracted shared helpers: `internal/atomicfile` (atomic temp-write+rename) and
  … (7 more in CHANGELOG)
Removed:
  - Unused legacy asset `docs/assets/icon.png` (superseded by the four brand SVGs
  - Plan documents for already-shipped features: `domain-stats-auto-ratelimit`,

# Alternative reverse-proxy: Caddy — the simplest option, fully automatic ACME
# with no separate certbot container. Caddy writes certificates as plain PEM
# under its own data directory, which this fragment bind-mounts to the host so
# SelfPost can read the same files.
#
# NOTE: Caddy's on-disk cert path includes
# the ACME CA's name as a path segment, e.g.
# <data>/caddy/certificates/acme-v02.api.letsencrypt.org-directory/<hostname>/<hostname>.crt
# This has been stable across recent Caddy releases but is an internal
# storage detail, not a documented public API — VERIFY the exact path against
# the Caddy version you deploy (`docker compose exec caddy find /data/caddy/certificates -name '*.crt'`)
# before wiring it into the volume mount below.
#
# Merge with the base file — run this from the deploy/ directory (Compose
# resolves every relative path in both files against the directory of the
# FIRST -f file, i.e. deploy/, which is why paths below are ./caddy/...):
#
# docker compose -f docker-compose.yml -f caddy/docker-compose.caddy.yml up -d
