If your linux box is just a passthrough to your winnt box, then there's
probably little you can do to filter spam at the linux box. Even a
statefull firewall would have problems distinguishing spam mail from other
well-formed emails. It's not the packets form that makes it spam, it's the
contents.

AFAICT, you have two options:
1) install a spamfilter package in your WinNT email package, or
2) move to a Linux-based email server, and install a spamfilter on it.

Of the two, the WinNT solution is likely to be costlier. OTOH, it's not
recommended that you run services (like sendmail) on a firewall.

Your choice, of course.
