[Exim] Howto autoreply to all disk quota exceders?

Hi, I just want to set in Exim that if a disk quota is exeded, then
instead to leave the message in the queue, send a message back to the
sender.

Does any one set this up in exim?

BTW, I tried adding a rule for the queue, but didn't work for me
because I use MAILDIR.

Any help is apreciated.
