How does a resolver do DNS validation? The MTA (Postfix latest stable) 
on all the sites I administer does DNS validation for each message it 
receives, and if an address isn't valid it gives an smtp 450 - till the 
sending MTA gives up in the end - or adapts. But how does a resolver do 
DNS validation?
