prevent certain email from ending in defer queue

[Kim Johansen]

Hey all,

I have a mail server with Postfix and Dovecot running, where I use 
Dovecot quota system.

When a mailbox is full we return an email to sender to inform that the 
email could not be delivered, but that will also happen if it is a spam 
mail get though to a mailbox, and that reply often end up in the defer 
queue.

My question is if it is possible to configure postfix to only try to 
deliver these replies one or two times and then drop them?

Thanks,

Kim Johansen
