Because of the way milter works, you cannot skip MD on a per-user 
basis.  There are two approaches you can take, both inside mimedefang-filter:

1. Use filter_recipient and the ACCEPT_AND_NO_MORE_FILTERING return code - 
which has the disadvantage that you stop filtering for any other recipients 
of the same message.

2. Check the list of recipients before doing the actual spam scanning 
(right before calling SpamAssassin, for instance).  This has the same 
disadvantage, but you can work around it using stream_by_recipient in 
filter_begin - which of course has its own disadvantage (resending the same 
message once per recipient).
