- just as an acceptance code is returned for each accepted recipient,
so, too a rejection code is returned for each one that is unwanted.
- as with any other rejection, it may be temporary or permanent.
Either way... at final rejection ELSE retry timeout, submitting MTA
generates a DSN to the sender so advising. Well 'real' MTA do. Dunno
about the 'bots. Or care.
