The only one of these programs I currently use is procmail, so I can't
vouch for _exactly_ how to work the others. However, there is usually
somewhere in the config file for your MTA (postfix) that tells it where
to hand the mail off to. I could give you the section in my exim.cfg,
but it would be useless with postfix. Somewhere in the postfix docs,
there has to be something that documents the handing off of mail to a
program like procmail.
Likewise, spamassassin docs have instructions for adding spamassassin to
your procmail config file. It's a recipe or two that will tell procmail
to force the mail through spamassassin. Since you'll want to get the
mail back out, you'll need another recipe to dump the mail somewhere. I
think you mentioned that spam goes to a single address and other mail
goes elsewhere. Procmail with use postfix again to deliver the mail.
In any case, the docs for all three programs should give you clues. Your
diagram above is correct. Sorry, I wish I could assist more, but I don't
use two of the programs you mentioned.
