@ -24,6 +24,11 @@ The most noteworthy change of this release is the update of the container's base
- The script now uses `/etc/os-release` to determine the release name of Debian
- Removed custom installations of Fail2Ban, getmail6 and Rspamd
- Updated packages lists and added comments for maintainability
- OpenDMARC upgrade: `v1.4.0` => `v1.4.2` ([#3841](https://github.com/docker-mailserver/docker-mailserver/pull/3841))
- Previous versions of OpenDMARC would place incoming mail from domains announcing `p=quarantaine` (_that fail the DMARC check_) into the [Postfix "hold" queue](https://www.postfix.org/QSHAPE_README.html#hold_queue) until administrative intervention.
- [OpenDMARC v1.4.2 has disabled that feature by default](https://github.com/trusteddomainproject/OpenDMARC/issues/105), but it can be enabled again by adding the setting `HoldQuarantinedMessages true` to [`/etc/opendmarc.conf`](https://github.com/docker-mailserver/docker-mailserver/blob/v13.3.1/target/opendmarc/opendmarc.conf) (_provided from DMS_).
- [Our `user-patches.sh` feature](https://docker-mailserver.github.io/docker-mailserver/latest/config/advanced/override-defaults/user-patches/) provides a convenient approach to updating that config file.
- Please let us know if you disagree with the upstream default being carried with DMS, or the value of providing alternative configuration support within DMS.
- **Postfix:**
- Postfix upgrade from 3.5 to 3.7 ([#3403](https://github.com/docker-mailserver/docker-mailserver/pull/3403))
- `compatibility_level` was raised from `2` to `3.6`
