I'm coming into this discussion late, so I might not have all the facts.
On my comptuer, I run spamassassin from procmail, configuring that link into
procmailrc. I would think that you could write a very simple wrapper script
that, if the domain is one of those to be spamassassened, passes it on to
spamassassin, and otherwise simply passes back the proper info to procmail.
See the diagrams in this article:
I'd think that this "quick return wrapper" would work no matter where you plug
in Spamassassin, or probably spamd for that matter.
