Is there any simple way to have postfix block mail from a specific
address to another specific address?

I'm getting a lot of spam from a certain (forged) address. It's all
copies of some virus, and it's eating enough bandwidth that I'd like to
kill it at the server, ideally before the message body gets sent. (It's
trivial to filter later with procmail/spamassassin, but the goal here is
to avoid the waste of bandwidth.) I don't really want to reject all
email from that address -- there are other users on this mail server who
might conceivably want to get legitimate email from that address.

I looked at the postfix docs on filtering, etc., but it gets really
complicated really fast. Is there an easy way to just kill anything
sent from ab to cd?
