[courier-users] how to immediately bounce emails from users over quota?

[Gordon T. <go...@en...>]

Hi, our organization has setup filesystem quotas. Is it possible to have 
maildrop immediately bounce emails sent to users who are over their 
quota (and with a graceful error message)? As I understand from 
discussions with the Postfix people, I just need to have Maildrop report 
a permanent failure and Postfix will deliver the bad news to the sender. 
Is this possible?

Thanks to any and all who may be of assistance.

Cheers,

Gordon
