What is the address that bounces? Who bounces it? Is it the machine on
which it is being sent (let us call that hostC)? If so, the problem is
in the DNS. Without an entry for hostB, there is no way hostC can tell
where to send the message if it is addressed to xx@hostB. That is,
assuming hostC is "any old host on the net". If hostC is restricted to
being one of your own hosts, you could do the routing by other means.
If it is hostA that is bouncing it, then there is something weird going
on if it can itself send to hostB. But wait, you are using some kind of
alias. What is the address that is being bounced? Is it
"testmail@hostA"? What is qualify_domain on hostA?
