Proxmox Mail Gateway 7.2 is out! It has been exactly a year since the last version, but today we are pleased to announce a new version of our email security solution. It's based on Debian 11.5 (“Bullseye”), uses the newer Linux kernel 5.15, as well as ZFS 2.1.6. The latest upstream release of Apache SpamAssassin 3.4.6 with an updated rule-set, and PostgreSQL 13.8 are included.

We have added support for Unicode characters and you can now better handle SMTPUTF8 emails. And a lot of improvements for the quarantine web interface.

Countless bugfixes and other smaller improvements are included as well, see the full release notes.

Thank you all for supporting the Proxmox Mail Gateway project over the last 17 years!
