DSPAM is an open-source, freely available anti-spam solution designed to combat
unsolicited commercial email using advanced statistical analysis. In short,
DSPAM filters spam by learning what spam is and isn't by learning
each user's individual mail behavior. This allows DSPAM to provide
highly-accurate, personalized filtering for each user on even a large system
and provides an administratively maintenance free solution capable of learning
each user's email behaviors with very few false positives.
