K9 is an email filtering application that works in conjunction with your regular POP3 email program and automatically classifies incoming emails as spam (junk email) or non-spam without the need for maintaining dozens of rules or constant updates to be downloaded.

Although K9 is a Bayes theorem-based email classification program, such as Popfile or SpamBayes, it is specifically written to only differentiate between spam (junk) email and good email. It is written in C++ as a native Windows application and thus only works on Windows operating systems.

It uses intelligent statistical analysis that can result in extremely high accuracy over time since K9 learns from its mistakes and becomes better and better at being able to identify spam. More importantly it learns to recognize what you individually consider to be spam.

More information and detailed instructions are available at the K9 homepage. There is also a French version and guides in German, Spanish, Italian, Russian and Swedish (along the English one of course).
