Talk about the law of unintended consequences. This gives an immenseOne has to remember that MAPS killed open relays quite quickly - behavior modification works. The operators of MTAs behind generic addresses are almost all insignificant and can easily adopt a smarthost once they realize they need one. I understand it is hard to make major ISPs kowtow to RFCs. This isn't in that league of difficulty at all.Even if it were "the solution", the PBL with something like 5-6 years of accumulated "pool addresses" behind it (from many many sources) should demonstrate that it's no easy task. Pool listings are _frightfully_ expensive in man-hours to maintain.
