mix 8ce050ef7f release: 0.1.0: Phases 0-11: panel, Postfix/DKIM, milter, backup, Docker image
Initial feature-complete implementation of the v1.0 specification (phases 0-11 of `docs/implementation-plan.md`).
Added:
  - Panel (Go, single static binary) with SQLite persistence, one-time
  - Domain management with per-domain DKIM (RSA-2048, generated in pure Go) and
  - Application (sender identity) management: SASL credentials via `sasldb2`,
  - Full Postfix relay config generated from env at container start: SMTPS 465,
  - Journal milter (pure Go, `go-milter`) recording every send to `send_log`;
  … (6 more in CHANGELOG)

Full detail: CHANGELOG.md (0.1.0).

# Extracts a PEM cert/key pair for one domain out of Traefik's acme.json
# (spec 10.3: "Traefik — сертификаты в acme.json, потребуется шаг извлечения
# PEM"). Run this on the host, after Traefik has issued or renewed the
# certificate, and again on a schedule (cron/systemd timer) since acme.json
# is not itself watched by SelfPost/Postfix.

# Requires jq. Usage: ./extract-cert.sh <acme.json path> <domain> <output dir>
