Barracuda Networks, the leading provider of enterprise-class spam firewall solutions, today announced the immediate availability of a Microsoft Outlook plug-in that will seamlessly integrate with the Barracuda Spam Firewall 300, 400 and 600 models. With this latest upgrade, Barracuda Spam Firewall owners using Microsoft Outlook can help train the Bayesian filters to more accurately identify spam with a simple click of a button in the Outlook toolbar.

With success rates greater than 99 percent, Bayesian filtering is recognized by the industry as the most accurate method for blocking spam. To ensure the accuracy of these filters, the Bayesian filter should be trained to learn and recognize the email patterns of each user. The first layers of the Barracuda Spam Firewall effectively block the most obvious spam messages, however, more obscure spam requires additional computation in order to determine message legitimacy. This additional computation is achieved through Bayesian analysis.

The Barracuda Spam Firewall's Bayesian filters build and utilize unique databases based on the statistical frequency of word occurrence of each user's previous email activity. For instance, email messages containing the word "Viagra" would be considered spam by a majority of email users, however, a pharmacist or physician may still need to receive legitimate email containing this word. With the Barracuda Spam Firewall, the more frequently a user designates spam from legitimate email using the "spam" or "not spam" icons on the Outlook toolbar, the more accurately the Bayesian filter will determine which of the final few questionable emails should be allowed through to the user's inbox.

"Bayesian filtering is the most accurate of the ten defense layers utilized by the Barracuda Spam Firewall," said Dean Drako, president and CEO of Barracuda Networks. "The first layers of defense successfully eliminate the majority of spam, leaving only a small percentage of the most elusive spam to be filtered by Bayesian analysis. We are confident that the new Outlook plug-in will further the Barracuda Spam Firewall's effectiveness by allowing the user to train the Bayesian filter."
