This is kinda hard.
If an attachment is there and the filename doesn't end with '.zip',
what do you want to do with the mail? Bounce it?
Where do you want to test the ".zip" thing? In content-type 'name='
or content-disposition 'filename='?
Here is my 5-minute attempt, which may give a starting point

* ^mime-version:
* ^content-type:.*multipart
* B ?? ^content-type:
* B ?? ^content-disposition:.*attachment

LOCKFILE=/tmp/munpack.$LOGNAME

( munpack -C $T 2>/dev/null; rm -rf $T; ) | \
grep -iv -e '\.desc (' -e '\.zip (' )
LOCKFILE
# If previous action line executed SUCCESSFULLY, i.e., if
# there were files other than '.zip' and '.desc' then message
# is BAD!

# If we get here, then the "grep" must have failed, so the

OK, that took longer than 5 minutes, it's completely untested, use at
own risk, etc.
