You might find it much easier, although still a lot of work, to install a relaying mail server on the firewall that uses SpamAssassin and Razor called from the MIMEDefang milter in sendmail. I've also seen a Webpage somewhere on doing this using Qmail and SpamAssassin (you might google for it). This is all free software - the only investment is your time. Asking iptables to do it is putting the load in the wrong place, and failing to take advantage of the work already done in using mail daemons for this task.
