Spam filter

Bogofilter is a Bayesian spam filter. It takes an email message or other text on standard input, does a statistical check against lists of "good" and "bad" words, and returns a status code indicating whether or not the message is spam. It is designed with fast algorithms (including Berkeley DB system), and tuned for speed, so it can be used for production by sites that process a lot of mail.
