[Exim] Exim should answer 5xx on mailbox quota

hi!

This question according FAQ Q0512, Q0821.

At the check_rcpt ACL exim should check per-user quota and answer 550 BEFORE
the DATA command sent. At least it prevents to sending of gigabytes
unwantable mail thru the net.

Please, help me. How can I set it up in Exim?

Retry config "* quota" doesn't mean what I said.


Thank you,
bye
