Proxmox Mail Gateway 8.1 is available! The new version of our email security solution is based on Debian 12.5, uses the newer Linux kernel 6.5, as well as ZFS 2.2.2. The latest major version of Apache SpamAssassin 4.0.0 and PostgreSQL 15.6 are included.

We have enhanced the object-oriented rule system and added a "match-if" mode providing more flexible control. Countless bugfixes and other smaller improvements are included as well, see the full release notes.

Thank you for supporting the Proxmox Mail Gateway project! Your contributions and feedback, tests, bug reports and patch submits are always welcome!
