It is not a question of whether exim should be notified of the rejection.
The question is should exim be able to resend the rejected message two or
three times before bouncing it back to the original server?
For example, this morning's rejection resulted from a malfunctioning
receiving server. Once we were notified that it had been fixed the senders
were advised to resend the rejected messages. What is sought is a way for
exim to do it automatically and bounce back only as a last resort.
