How about one of the spamassassin gurus here gives us a hand? You 
*could* set up a spamassassin rule that gives a strong negative value to 
something in the headers. I can see from a message that just came in 
that Dhawal is suggesting something similar.

My headers look like:

Return-Path: <alex at nkpanama.com>
Received-SPF: pass (nkserver.nkpanama.com: authenticated connection) receiver=nkserver.nkpanama.com; client-ip=201.226.170.130; helo=[192.168.100.101]; envelope-from=alex at nkpanama.com; x-software=spfmilter 0.97 http://www.acme.com/software/spfmilter/ with libspf2-1.0.0;
Received: from [192.168.100.101] (nkcenter [201.226.170.130])
	(user=alex mech=PLAIN bits=0)
	by nkserver.nkpanama.com (8.13.1/8.13.1) with ESMTP id k43GkwD0017301
	for <alex at nkpanama.com>; Wed, 3 May 2006 11:46:59 -0500


So I could set a rule that hits on "authenticated connection", "user=whatever mech=whatever bits=whatever" or something similar. I'm using sendmail, btw.
