That's the problem I tried to describe. In my experience, the message goes
back to the queue and will be retried to a.mx.quadpro.stupendous.org by
QMTP later. And this will happen until qmail-send decides the message has
been in the queue too long, whereupon it will be bounced.
However, I'm not 100% sure about this, as my network setup is a little too
small and limited by university-controlled firewalls and university-
administered DNS servers.

Er, yes.
