Like Felix I'm skeptical about the value of general anti-virii programs
running as gatekeepers on Linux servers.
However, I have found AMaViS (A Mail Virus Scanner;
http://amavis.org ) very useful for filtering out e-mail viruses, a very
annoying and prominant subgroup of viruses.
AMaVis works with qmail but requires a separate anti-virus scan
engine to work in conjunction with it. It supports a number of such
scan engines. For example, I use McAfee's VShield 4.x scan
engine under a corporate license.
My enterprise also uses PC-based and Novell-server based anti-
virus software but these have the disadvantage of needing to be
properly configured, and the weakest link in this kind of distributed
defense would be the handful of PCs or servers that had a
misconfiguration.
With AMaViS at the pass, there's the ability to passively run e-mail
virus filters as every single e-mail comes in.
If you decide to use this or a similar approach, you need to make
sure that a cron job runs to periodically update the ant-virus .dat
files from your scan engine's website. Otherwise your database of
antiviral signatures gets obsolete.
