Answer

Barracuda Spam Firewall is an integrated hardware and software solution that is used to protect TVCC email from spam, virus, spoofing, phishing, spyware attachments, and denial of service attacks. All email before it is sent to a users inbox is sent through the Barracuda Spam Firewall to be processed. Addresses that appear on your Whitelist are automatically sent to your inbox while addresses on your Blacklist are deleted immediately. The remaining email is scored (evaluated as to the likelihood that it is spam), and handled according to your configuration settings. It takes about 200 spam and non-spam messages before the Bayesian analysis starts to recognize and block spam. (See definition list for Bayesian.)
