I have inside/outside servers with most MUA submission to the
inside and MimeDefang running only on the outside which
mostly avoids the problem.  However I still skip the slow checks
on mail coming from the inside.  Someone posted a
relayIsTrusted() function a while back on the mail list.
I use that to skip all but the virus check which would
probably be fast enough even if the MUAs submitted directly
to that server.
