Yes.  You just write the Perl code.

Yes.  You just write the Perl code (perhaps you see a pattern in my
answers. :-))

MIMEDefang is extremely stable.  We have customers using our commercial
CanIt software (based on MIMEDefang) with uptimes of over 200 days.

MIMEDefang is a fairly decent performer.  With SpamAssassin scanning
and Clam virus-scanning, a dual Xeon at 2.4GHz with 2GB of memory
should easily handle 500 000 to 600 000 messages/day.
