Hello,
Besides just checking for malware with:
# Reject virus infested messages.
deny message = This message contains malware ($malware_name)
malware = *
Is it possible to look inside a zipped file for M$ files
such as .exe .pif…… and bounce with something like
A 550 the file you sent, has self executing code, please rename
the file(s) and re-zip and send again…..
Thanks.
