You can rename a file all you want and stick it in a zip file...it still won't work with Symantec's product.
Symantec is smart enough that it doesn't look just at the extension of the file in question, it looks inside the properties of the file somehow and determines what the file type is that way. We've had people try it and it doesn't work...they still get blocked at the firewall. -----Original Message----- From: Ben Winzenz [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 20, 2003 6:23 AM To: Exchange Discussions Subject: RE: SAV for SMTP Gateways - blocking extensions within ZIP?? It's known behavior (i.e. default and Symantec knows about it). If you want someone to send you a zip file that contains a file with an extension you are blocking, you can either have them password-protect it (which Symantec can't scan - assuming you are not blocking encrypted containers), or have them rename the file in the zip.

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?
