ISPs that subscribe to MAPS RBL are saying that they believe that open relays should not exist, that MAPS should be able to test for this condition, and that they don't want to receive e-mail from non-compliant hosts.

This is the source of confusion... right here. This person does not know the difference between MAPS and ORBS.

Wow, this text was incredibly ambiguous.

MAPS offers three different lists: RBL -- the traditional realtime black hole list, of confirmed, unrepentant spam sources DUL -- the list of provider dial ports, as you shouldn't be receiving email directly from some other ISP's dial pool in most cases RSS -- 'relay spam stopper', an open relay list which is much more tightly run than ORBS, as RSS requires samples of spam that have come through the relay, whereas ORBS actively hunts open relays, whether they are being used for spam or not. In all cases, proof of spamhood is required. The do not scan for innocent open relays.
