Speaking on behalf of the poor distributed.net mailserver in question, 
this is only half the story when it comes to the damage done by qmail's 
behavior in this case.  Not only is the accept-then-bounce behavior 
generating annoying and irrelevant bounces for innocent email 
addresses, it's also generated an outbound queue of bounces to domains 
and emails which don't exist which numbers in the tens of thousands.  
These mails clog up the outbound queue for 7 days with qmail dutifully 
attempting delivery periodically never quite coming to grips with the 
fact that the addresses are pure bunk.

I switched my home server to postfix this past weekend and plan to do 
the same to the distributed.net servers now that I know how the 
conversion is done.
