spammers have a solution to this. they send to random hashes, e.g. ladd Nov 13 04:08:12 Disallowed gossinternational.com!ruiohfsd (gossinternational.com/124.172.212.142) to blocked name quanstro.net!b94cd358e11d3ffb43628c10bc786087 i think the idea of spooling email is largely discredited. it opens up the possiblity for backscatter spam, or the lack of delivery rejection notification. either one is not good. i think the acepting smtp server has to be in a position to make a definitive decision on disposition.
