We are excited to announce the availability of Proxmox Mail Gateway 6.1. The new version comes with some interesting new features.

We have updated the Mail Gateway to Debian 10.2 (Buster) and a 5.3 kernel with ZFS included. The new version 6.1 brings support for DomainKeys Identified Mail signatures (DKIM), a new attachement quarantine, adjustable SpamAssassin scores via GUI, and improved handling of Configuration and Rule changes in a cluster. As an experimental feature, the support for “Before Queue” filtering can be enabled.
