Short answer: 
	Go read RFC821/2 (and consider yourself insulted).

Long answer:
	Mail is a reliable, end-to-end service, and must 
	actively acknowlege both receipt and errors.  An
	exception is made for one case (where an error
	indication would be ambiguous), but in that case
	a duty to reurn a mail message with notice of
	the error is imposed.

	Gateways which do not support the above are possible
	(the PC-critters are good at that), but no-one claims
	they're standard-conforming.
