This is the mailinglist of the well-known OpenSource anti-spam tool SpamPal programmed by James Farmer. SpamPal is a transparent mail proxy for POP3, IMAP4 and SMTP which uses dozens of blacklists like SpamCop, ORDB and SpamBag to identify spam mails. In addition to that there are several plugins for "bad words", regular expressions and a bayesian filter to enhance the spam recognition. SpamPal has a strong increasing user community and offers a lot of support like a few dozen manuals for mail-clients and a forum.
