For those interested, I have the following notes on this matter:
With Exchange 2003, it IS possible to make Exchange reject SMTP recipients
that don't correspond to valid mailboxes (or public folders, or
distribution lists).

For Exchange 2003, look here:

According to this post, there is a plugin for 5.5 that can do it:

(though the working is slightly ambiguous, I'm pretty sure that the
plugin is for Exchange and not for MimeDefang).
According to Edgar Lovecraft, regular on this list, you can do it for
Exchange 2000 with something called a "Custom Event Sink":
