Fast, teachable, learning spam detector
Bogofilter is a trainable email spam detector.
Bogofilter takes an email message or other text on standard input, parses it into words, does a statistical check against databases of “good” and “bad” words, and returns a status code indicating whether or not the message is spam. Bogofilter decodes base64 or quoted-printable encoded texts and ignores non-text attachments and HTML comments.
The supported database backends are Berkeley DB, QDBM and SQLite3.
