SMSME 5.0 - Scanning zip attachments for disallowed file types?
We are running SMSME 5.0 on our Exchange 2003 server and I cannot seem to find any option to scan zip attachments for disallowed file types (*.exe, *.bat, etc). We have Content Filtering rules configured to block undesired attachment file types but I see in the SMSME manual that it does not scan attached zip files:
Note: The content filtering engine does not evaluate any file extension names
that are inside the outer-most attachment, for example, the compressed files in
a .zip file.
Can scanning of zip files for specific file types (and filtering the disallowed ones) be accomplished via the "File Filtering Rules"?
