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).
