How can I generate an alert if user(recipient) gets more than the usual
message say 1000/hour instead of 100/day, thereby telling us something is
wrong with the account - possibly compromised or DDOS attack. We had an
instant like this few times (to well-known academics) and we would like to
stop this kind of problem as soon as possible, before the mailbox is full.
We are Exim 4.81
