We are very excited to announce the general availability of Proxmox Mail Gateway 5.2!

The Mail Gateway has been updated with all Debian security updates and with a 4.15 kernel. The improved quarantine web interface allows multi-selection of items and you can download emails in .eml format. Version 5.2 comes with a new mobile interface for the quarantine, based on Framework7. We have improved the Message Tracking Center easing the debugging and rule setting. With the new appliance template you can quickly install Proxmox Mail Gateway as a privileged or unprivileged Linux Container. For all improvements and updates please see the release notes for details.
