ClamAV

ClamAV is an open-source antivirus engine designed to detect Trojans, viruses, malware, and other malicious threats. It provides a high-performance multi-threaded scanning daemon, a command-line utility for on-demand file scanning, and an intelligent tool for automatic signature updates.

spam detection

Proxmox Mail Gateway uses various local and network tests to identify spam signatures. This makes it more difficult for spam senders to find areas that can be utilized to construct messages. Each email will receive an assigned spam score. The system attempts to optimize the efficiency of operating rules in minimizing the number of false positives and false negatives.

How to deploy Proxmox Mail Gateway in your network:

In a basic email server architecture, email traffic (SMTP) typically reaches the firewall and is then forwarded directly to your mail server.

By implementing Proxmox Mail Gateway between the firewall and mail server, all email traffic (SMTP) will be forwarded to the Mail Gateway first, and all unwanted emails will be filtered, deleted, or rejected (pre queue filtering) before being forwarded to your mail server.
