Py-spambayes

Bayesian anti-spam filter written in Python

SpamBayes is a tool used to segregate unwanted mail spam from the mail you want ham. Before SpamBayes can be your spam filter of choice you need to train it on representative samples of email you receive. After it’s been trained, you use SpamBayes to classify new mail according to its spamminess and hamminess qualities.
