Use smf-sav.  It queries the Exchange server for a valid address using
LDAP so you don't have to update the access list every time you add a
new user.  Pretty easy to set up too, although it is a little vague in a
couple spots - but that's what we're all here for. :-)

It also caches the result, so if something comes in for
joe at yourdomain.com it remembers that joe is a valid user and doesn't
have to do a new lookup until it times out some hours later.  You can
adjust the timeouts.  Naturally it remembers invalid users as well...
