[Mimedefang] Using Spamassassin's spamd/c

[listuser at neo.pittstate.edu]

I couldn't find a search ability for the archives but I did check the more
recent ones and didn't see anything that answer my question.

I'm trying to figure out how to make mimedefang use SA's spamd/spamc.  I
really like MD's configuration ability for the headers/report/subject
line.  I don't like the fact that it appears to spawn a SA process for
each incoming message (this is what it appears to be doing).  I tried a
spamd/spamc setup with procmail today and liked the way it conserved
resources.  I also liked the ability to do DNSBl and razor checks.  I
really need the reporting and conditional subject editing that MD gives me
though.  Can anyone tell me how to use spamd with MD, specifically MD's
multiplexor?

I understand that using SA with MD prevents a lot of SA features from
working.  The way I understand it, no SA config files are read when SA is
run for MD and the MD SA config files are greatly limited in what actually
works.  If any one can speak to this, I'd appreciate it.  I'm not sure
what all I'm missing out on.

Finally, my last question is about whitelisting local users, ie SPAMFRIEND
users that don't want filtered mail.  In the procmail setup, I was going
to either look for a $HOME/.nospamfilter in the user's home directory or
refer to a text file of userids that want unfiltered mail.  The text file
would be built from Sendmail's access list of SPAMFRIEND (or the 8.12
syntax) users.  Is there a way to make MD also check for either of these
possibilities?

Thanks
