You could create a shell script which does an "unzip -l" and greps
for ".mp3", returning 1 if found, zero if not. Plugging this into
the Sanitizer using the "virus scanner" interface is then a
relatively straightforward procedure.
But I think it's nasty to block mp3 files. There are plenty of
legitimate mp3s out there from struggling artists who *want* to
reach a larger audience...
But that discussion is definately off topic for this list. :-) So
