Scan the mimedefang-filter manpage for "stream_by_domain", which
contains roughly the code you're looking for.

There is no way to do this outside mimedefang, so you'll have to
short-circuit all mimedefang routines for the second set of domains.

You might want to rethink not having virus filters for the second
domain, though, especially with a new pretty big Sober outbreak
happening right now.
