MIMEDefang, like most other milters I know of, runs as a daemon on the 
same host as sendmail.  You *might* be able to run MD on a different 
host than sendmail, IIRC the milter interface allows this.  Check the 
sendmail docs.

MIMEDefang, by default, uses SA as a Perl library.  This means that none 
of SA's settings for adding header(s) or encapsulating the spam will do 
anything.  To use SA's settings, you have to either call the 
spamassassin "binary", or spamc (which passes the message to spamd for 

IIRC someone came up with a patch for MD to use spamc/spamd instead of 
calling the SA libraries directly;  check back through the list archives.
