If exim gets a 5xx when trying to send an NDR, then it freezes the
message and does not retry. Your problem is that you want your system
to stop retrying to send NDR when it only gets a 4xx. The best
suggestion I have for you is to use exipick in a cronjob and try to
detect these failures.

exipick '$host_lookup_failed'
