[Mimedefang] Troubeshooting SA under MD

[Al Sparks]

I posted a specific question regarding getting DCC working on 
SpamAssassin run through MimeDefang.  Nobody has taken a nibble at it, 
so I thought I'd ask a more generic question.

What is the best way to troubleshoot SpamAssassin when running through 
MimeDefang?  There are some people out there that get into the innards 
of the SA modules through MimeDefang, so I thought I'd ask, is there a 
way to get MD to do more verbose logging as to what SA is doing?

Calling
   spamassassin --lint -D
doesn't seem to be working, because it doesn't seem to be running 
under the same conditions when called by MD.

Any hints?
