And why in heaven's name would you want to do that?  There are several
viruses that send the payload contained inside a .zip file, the worst of
which is the one that a lot of people on this list just got through patching
systems for:

Subject: SAV for SMTP Gateways - blocking extensions within ZIP??



I am running Symantec Antivirus for SMTP gateways version 3.1.0.29.  This
has an option to block attachments by extension, but this blocks files even
when they are in ZIP files.  The Symantec (Norton) antivirus that runs on
our exchange server (5.5) has a registry setting to control whether or not
it looks in ZIP files for bad extension (it always scans for viruses in ZIP
files). 

Does anyone know how to configure SAV for SMTP gateways to allow "bad"
extensions when they are stored in ZIP files?

Tom
