Is it possible to run an external handler when a message delivery error occurs in Exim?

Question

linux

Hello.
Interested in the following. Is there any way to run an external handler when a message delivery error occurs in Exim. To put it simply, if Exim catches 111, -52 or -51 errors, then it runs some external script and sends it the email that caused the error.
If Exim doesn't know how to do this, then maybe you can tell the MTA who can.

Also interested in the question.
So far, it has been implemented like this: all bounce messages (which go to the sender when the letter is not delivered) are caught ( habrahabr.ru/post/164661 ), parsed, the initial msg_id is taken from there and logic is done on it.
