My suggestion: Don't. Do it the other way around. Push all valid e-mail
adresses to the MailScanner box (I posted a script to do this earlier.
Have a look at the FAQ). If you need auth, consider RADIUS instead of
LDAP. LDAP will work of course but it is quite messy and from my point
of view opens up too many possible security holes on an Exchange box.
