I'm afraid I've never got round to formalizing the bounce messages. It
is probably something that should be done, but there always seems to have
been something more interesting/useful/urgent to do.
One of the problems about the reason is that sometimes the reason isn't
known. Or there may be several reasons. Consider a domain with two MX
records to two diffrerent hosts. One times out, the other says
"connection refused". They both go on doing this for 5 days; the message
then bounces. Which reason would you like?
Another message for the same (timed out) host arrives shortly
afterwards, before the next retry time. In the default configuration,
Exim bounces it without trying another delivery. The only reason is "all
hosts timed out after a long retry period and retry time not reached".
