[Mimedefang] Specifying valid users?

Hi all, I've noticed that lately a lot of spam is directed to people
that don't actually exist in my company.  It looks like spammers are
just guessing names of people who might work here.  Since my Linux box
is just a relay for the exchange server I don't know of anyway to
actually do checking to see if a user exists.  Also, since anything
labeled as spam gets redirected to a specific mailbox it doesn't even
get rejected at the exchange server.
Any ideas?
