There's no way to do that with SpamAssassin itself. Once you send something to SA, it will do the whole process (there's short circuiting, but that's not really what you want here). It sounds like you're trying to not filter internal mail but filter external mail, so I would recommend two things:
a) Ideally, have your MTA listen on two different IPs, one internal and one external. Apply different rules depending on which IP is being used. You mentioned using Postfix, and doing this is fairly trivial. b) Send the mail through something like procmail. It can make lightweight decisions about "if this header exists do X".
