I completely disagree with you there I'm afraid, the most effective
filtering works on parameters other than the actual email contents, for
example HELO/EHLO, sender address, sender domain, SFP, sending IP address,
RDNS, active directory checks etc.

If by effective you mean, "the most", then of course. If by effective
you mean, not dropping legitimate mail, then probably not.

Except using RBLs to drop mail is not the same as SPAM filtering since
you are not checking the contents of the actual message but simply
denying delivery.
