That is what should happen. The DNS server replied that the
destination does not exist.
Postfix will retry when the DNS server is unavailable.
This of course, assumes that the DNS server is working properly.
If it replies with DOES NOT EXIST for other errors then all bets
are off.
You can kludge around this with soft_bounce=yes but that creates
other problems, such as people never finding out that their
mail is stuck in the queue.
