1. A junk-email filtering program for procmail This package uses procmail filtering algorithms to detect junk email. This results in internal procmail variables being assigned to indicate the reason why the email has been classified as junk. The user can then use those variables within their .procmailrc file to deal with the junk in any way they see fit. There are a number of filters available in the package, and can be selected from a simple config file on a per-user basis. From Debian 3.0r0 APT
