Overview

The Barracuda Spam Firewall is an integrated hardware and software solution that provides powerful

and scalable spam and virus-blocking capabilities that do not bog down your email servers. The system

has no per-user license fee and can scale to support tens of thousands of active email users.

Using the web-based administration interface, you can configure up to ten defense layers that protect

your users from spam and viruses. The ten defense layers are:

■ Denial of service and security protection

■ IP block list

■ Rate control

■ Virus check with archive decompression

■ Proprietary virus check

■ User-specified rules

■ Spam fingerprint check

■ Intention analysis

■ Bayesian analysis

■ Rule-based spam scoring
