Optional bulk mailboxes for users
Barracuda Spam Firewall provides optional bulk inboxes so that users can direct spam messages straight into these areas. This prevents spam from cluttering up their main mail system. These bulk email boxes can be checked periodically or ignored.

Powerful, Complete Solution
The Barracuda Spam Firewall is compatible with all email servers and can fit into nearly any corporate or small business environment. It is used by small organizations with as few as 10 employees and large organizations with as many as 200,000 employees. A single Barracuda Spam Firewall handles up to 100,000 active email users. Multiple units can be clustered together for even greater capacity and high availability.

The Barracuda Spam Firewall protects your email server with twelve defense layers:

* Network Denial of Service Protection
* Rate Control
* IP Reputation Analysis
* Sender Authentication
* Recipient Verification
* Virus Scanning
* Policy (User-specified rules)
* Spam Fingerprint Check
* Intent Analysis
* Image Analysis
* Bayesian Analysis
* Rule-based Scoring
