Proxmox Mail Gateway

Proxmox Mail Gateway at a glance

Proxmox Mail Gateway is an open-source email security gateway (anti-spam and anti-virus) that sits in front of mail servers, from the makers of Proxmox VE. It ships regular releases plus security fixes; as an internet-facing mail-filtering appliance, timely, careful patching matters.

For admins updates run through the web UI or apt against the Proxmox repositories — back up the configuration first, and read the release notes before major jumps. As a device in the mail path handling untrusted messages and attachments, keep it current (filtering engines and the base system both receive fixes) and keep management access off the open internet. After updating, verify that mail flows, filtering works and quarantine is accessible — a broken mail gateway blocks legitimate mail. Track the version and its support window, and mind the subscription/repository choice for production. Patchletter surfaces new Proxmox Mail Gateway releases.
