To a greater or lesser extent, and depending on the version. Here comes
my stock answer to this question, collected from comments mostly on this
list over recent times:
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 wording 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":
