I guess this is because other than DSN there is no accepted written 
standard - and DSN is pretty much unworkable in practice (it has too 
many additional implications).

Just to make things nastier, one of the things asked for by exim users 
was customisable bounce messages - and pretty much all elements can be 
morphed.  The one very easy standard piece of an exim bounce is the 
x-failed-recipients header - if its there then it lists the recipients 
that failed (addresses given in the form that the bouncing MTA received 
them - this means its still a problem if a message forwarded from a 
remote machine bounces since the address will be different to that the 
list knows about).
