Spam Terrier 2.0, which provides users of Microsoft Outlook, Outlook Express, Windows Mail (in Vista) and now The Bat! with self-learning protection against unwanted email has been unleashed by the computer security experts at Agnitum, publisher of the acclaimed Outpost Pro product line.

Chief Software Architect at Agnitum, Alexey Belkin, declared: "Spam Terrier is now on friendly terms with The Bat!, as well as 64-bit Windows and Vista email clients." He continued: "Our users began asking for broader email client support for some time, and we're pleased to finally be able to deliver this support, along with additional new functionality to further improve Spam Terrier's ability to guard users' inboxes against spam."

Spam Terrier 2.0, as the previous version, is free to all users and now provides even more wide-ranging protection for email users, around the clock and around the globe. With the new support for popular email client The Bat!, we can confirm that Spam Terrier is going to bat for all email users, no matter what their outlook …

To help users get started with teaching the software their personal definition of spam, Spam Terrier offers a user-friendly interface and easy customization. Ensuring significantly fewer false positives and misjudged messages, based on Bayesian principles, the self-learning engine, takes over.

Rather than the more typical criteria-driven approach of other anti-spam products, Spam Terrier is 'behavior'-driven. In other words: users can select what they consider spam and teach the product to recognize the specific behavior patterns of junk mail.

The more you train Agnitum Spam Terrier, the better its nose for inappropriate mail. This is achieved through a system of "spam scores", which classify a message as "not spam", "probable spam" or "definite spam". In order to adjust the software's level of tolerance for different types of message, users can alter the principles for such classification. But however "tolerant" the application may be, it will never let unwelcome guests in - Spam Terrier is constantly scanning new mail in search of fresh spam samples. Spam Terrier uses this data to update its database, increasing the accuracy level dramatically.
