True. If your application is monolithic, it's easy, but if it is a
component system (e.g. ezmlm) it's expensive since MIME parsing becomes
necessary in many subprograms. For ezmlm, DSN also lacks function:
bounce handling is done without it. It becomes an exercise in parsing
for the sole purpose of weeding out delay notifications.
