First of all, you're talking about deferrals, not bounces. If a mail
delivery results in a permanent error (like "no such email address here"),
the MTA returns it to the envelope sender. That is called a bounce.
You can control (to some extent) how long qmail will keep a given message
in the queue by setting /var/qmail/control/queuelifetime to the number of
seconds you want -- it defaults to a week. However, you will have to hack
the code if you want to control how often qmail tries delivering a message
in the queue.
