do it at your gateway if at all. don't put excess load on your exchange server 
and don't tell me you don't have a mail gateway or i will scream!!
but the question still would be why, use other methods to block spam!!

How do I get Exchange to do a reverse lookup of the IP address it's
sending an email to before sending it to check if it's valid or not, and
if it's not valid to drop the email all together?
