Mail traffic is at an all time maximum here with the Swen/Gibe.F Microsoft mail worm. As the messages are 150 KB in size, a spamfilter solution as the SpamAssassin - Procmail combination isn't optimal as all mail is still being downloaded to my workstation. So I decided to fight the spam the place where it should be, and installed MailFilter, a nifty mail filtering program which even works for POP3 mailboxes.
