Optional inbound relay (backup-MX / forwarder) on port 25, off by default. Mail is accepted only for domains configured in the panel and forwarded to an upstream; there are still no mailboxes. A dedicated security review of the inbound path is still open on the plan (Fable). Added: - `INBOUND_RELAY_ENABLE` (default `false`): when true, Postfix listens on - Panel **Inbound** pages (global administrator): domains, upstream host/port - Optional `INBOUND_ANTISPAM_MILTER` on the inbound listener only, plus - Inbound rate limit (`INBOUND_RATE_LIMIT_MESSAGES_PER_IP`, default 20) and Changed: - Compose publishes host port 25 even when the flag is off (nothing listens - Full-backup restore Resync also rebuilds inbound maps when the flag is on. Full detail: CHANGELOG.md (1.4.0).
