Ah, excellent!

"In all cases, if a check returns an indication that the operation,
message, or connection should be rejected, or should be unconditionally
accepted, then no
     further checks are performed for that operation, message, or
connection respectively. "

This explains a lot of things.

Hmm.  This will require some thinking to keep it efficient.  :/

I'm already doing stream_by_domain() on the current production system to
avoid spamscans on backup-MX domains;  I think I can see how that would
work for other domains.

Coincidentally, it'll allow finer-grained controls for customers.  <g>
At least, once I write the supporting web-based control panel code.
