How to customize "mailbox full" bounce message?

[freakysid]

I'm not queuing mail for users with full inboxes on most of my servers. How do I customize the message received by sender when an email bounces because the user's mailbox is full?

Example of what they get now

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  [email protected]
    mailbox is full

Example of what I what I would like it to say

This message was created automatically by mail delivery software.

recipients. This is a permanent error. The following address(es) failed:

  [email protected]
    mailbox is full

Please try resending your message again in one day's time. Hopefully the user will have downloaded or cleared their inbox by then.

or even...

Have you tried telephoning this person as obviously they don't know how to manage their inbox?

Any help would be appreciated.
