To be clear: because the legitimate mailserver with a proper non-generic

That's egregiously harsh. 

SORBS was blocking a customer for a generic reverse entry, I gave them a legit
looking reverse (that fwds properly too), solved, if a bit irritating. To
require the whole BLOCK be totally legit is too much.

Especially if they think the "block" is a /24 and you think it's a /27 and
somebody else entirely has the /27 either side of you. I've seen *that*
sort of brain damage far too often even in recent years. RFC1519 was 16
frikking years ago, and some people *still* aren't on board.
