The real use would be well before procmail, to avoid downloading junk in
the first place: POP3 (TOP 1234 0) or IMAP4r1 (A001 FETCH 1234
BODY[HEADER]) or even in a fast SMTP plugin (Postfix' smtp proxy
stuff). Makes fixing false positives difficult though.

I haven't looked at Animail yet (on sourceforge), it might support such
things (Python language).
