AntispamSniper for The Bat! provides a bullet-proof anti-spam protection for your mailbox. The unique combination of several methods for automatic email classification shows impressive filtering quality.

The statistical trainable classification algorithm has unique characteristics.

AntispamSniper for The Bat! will learn your private correspondence, extract the distinguishing features from messages of different classes and use that information for effective analysis of other incoming messages. The algorithm improves its classification quality continuously with each new learned message.

The messages from whitelisted senders are not filtered by other methods and recognized as non-spam at once. The whitelist is updated on learning automatically.

The filtering rules are recognizing spam and ham by specific combinations of symbols in a body and headers of the email messages. The rules are optional, because the trained algorithm and a whitelist are very effective. But the accurately assembled lists of rules may improve the classification quality in cases when the algorithm is unable to select a certain class for a message with high probability.

Exceptions are the empirical conditions for filtering. For example, large messages are probably non-spam. The presence of certain types of attached files also can be a good sign for recognizing message as non-spam.

The filtering log allows you to track back the history of classifying messages and training the plug-in.

Note: AntispamSniper for The Bat! has a commercial version and a freeware version. Both can be downloaded from Softpedia and you can register the commercial version by pushing the "Buy Now" button.
