An antivirus mailscanner should check the filesizes inside a compressed file like .tar.gz, .zip, .bz2, etc, BEFORE open the file for scanning.

A better approach is just to set proper process limits before spawning the antivirus checker. You can achieve this with softlimits (from daemontools), or with a simple script using standard shell facilities (limit/ulimit) . It doesn't require any change to your antivirus software. -- __ /*- Frank DENIS (Jedi/Sector One) <j () 42-Networks Com> -*\ __ \ '/ <a href="http://www.PureFTPd.Org/"> Secure FTP Server </a> \' / \/ <a href="http://www.Jedi.Claranet.Fr/"> Misc. free software </a> \/
