Using an MTA with the capabilities you need should be a prerequisite to
running an MTA.

I expect you could do it though I havn't tried myself because I'm not a
big fan of smtp-level rejects exactly for these reasons.  I just accept
and then discard (at least for known userids, but I don't expect many
people to be setting up forwards for non-existant userids).  I would
have thought that at the least you could accept it, detemine it's SPAM
and then have a procmail bounce-creating rule without all that much
