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

Fixed:
- The setup account's password is hashed at bcrypt cost `12` like every other

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

[1.3.0]
Security and quality after 1.2.5: domain-admin send-log authorization, fail-closed sign-in and application delete, level-2 rate-limit race fix, restore Resync, expanded tests, operator docs, release CI, and OFL for IBM Plex. Upgrading from 1.2.x is a tag bump; no migration.
Added:
- licence: the SIL Open Font License 1.1 text now travels with the IBM Plex
- docs: agreed roadmap item **queue-retries** — show this Postfix's retry
Security:
- The independent security review of the send-log authorization and
Fixed:

[1.3.1]
Retry policy in the panel, persistent Postfix queue, and self-contained full backups. Mail queue and delivery history show this Postfix's first retry, backoff cap, and queue lifetime. Deferred mail survives container recreate. Full backups now archive `data/`, compose, `.env`, and `certs/`; the archive layout breaks 1.3.0 flat backups (unpack those with `tar xzf backup.tar.gz -C ./data` as before). Upgrading from 1.3.0 is a tag bump; no schema migration.
Added:
- Mail queue and a delivery's history show this Postfix's retry policy
- docs: **Plan checklists** in [development.md](docs/development.md) — format,
- docs: **Implementation checklists** with model routing in
- docs: roadmap candidates **send-log-retention** (panel Settings for delivery
- Postfix queue under `/data/postfix/queue` — deferred and active mail survive
