“Blackhole Spam/Virus Filter provides spam and virus filtering using dot-files in all the major MTA/SMTP servers for UNIX and similar systems. It is easy for an individual user to set it up with shell account access and configure. It is different from other, similar programs, in that it executes a minimal number of programs to do the filtering, is able to use a MySQL database for the users’ configuration files, can be set up as the queue in Qmail, and have virtual users’ configuration files be found using the username/domain for the recipient. Multiple checks are available, and there open options on how to treat flagged email. There is logging to multiple entities, auto-expiration of flagged email, and scoring available so that multiple checks require matches that add up before blocking.”
