Personally I think this is partially a job for the MTA not MailScanner
per se. With sendmail you could do something like,

Got zip attachment drop into /var/spool/mqueue.in-dangerous.

And the MailScanner gets enhanced to something like

Dangerous Mails = /var/spool/mqueue.in-dangerous

Dangerous Mail Delay = 3600

But I would strongly advise against this. There are situations where it
is perfectly valid for someone to request a zipped file and they need it
now, not in 2 hours. So maybe there has to be a trade off somewhere, I
do not know :)

ON the other hand, doing it in the MTA can be very expensive, so this
could of course be done soley in MailScanner as well. I am just spilling
ideas :)
