How is email filtered?
Our Hosted Barracuda solution is deployed at the network perimeter so all incoming email must pass through all 12 defense layers of our clustered Barracuda Spam Firewalls before any of it can reach your mail server. The defense layers are grouped into two main classes: connection management, which involves dropping incoming mail connections before receiving messages, and mail scanning, which analyzes messages upon receipt. During the filtering process, emails are checked for new and familiar spammer attacks, viruses, and customized administrator policy violations.

Based on administrator and user preferences, spam can be tagged, quarantined or blocked.
