I may be wrong, but I believe you can already do that with DSN/MDNs. 
However, I have yet to see an MUA which does it even though it doesn't 
seem like it'd be that hard to do with the MUA requesting success DSNs 
and parsing the responses.

Maybe the JMAP server could handle the responses and somehow link the 
status to the sent message?
