POPFile 1.1.1 RC1 / 1.1.0

POPFile is an email classification tool with a Naive Bayes classifier, POP3, SMTP, NNTP proxies and IMAP filter and a web interface.
POPFile classifies email into categories you define. It can sort into spam and not spam or into any number of categories you like (e.g. work, personal, important project, hobby, etc.).
The classification is done using a native Bayes algorithm. In other words, POPFile uses statistics to track which words are likely to appear in which messages. This means that POPFile will adapt to the kind of mail you receive and needs to be trained.
Out of the box, it doesnt know anything about spam or how messages from your mother differ from those your friends send you. However, if you train it, it will soon learn how to tell these different kinds of messages apart.
POPFile is a cross-platform solution that will run on most platforms and with most email clients.
