Exim does not support any kind of delivery notification.
Comment 1: You can configure it to recognize headers such as
"Return-receipt-to:" if you wish.
Comment 2: I investigated the RFCs which describe the DSN system, and
there is even a bit of code in there (excluded by #ifdef) for
handling some of the data. However, I was unable to specify
any sensible way of actually doing anything with the data.
There were comments on the mailing list at the time; many
people, including me, conclude that DSN is in practice
unworkable.
Comment 3: There are those who want MSN (message status notification).
Such services are implemented in MUAs, and don't impact on
the MTA at all.
Comment 4: Personally, the only kind of delivery information I trust
is when I get a reply from the person I sent the message to.
