Should we have it? Why not?
Nominum's nameserver software has these features. Industrial strength nameservice, with lots of industrial-strength features, but at an industrial-strength price. I thought BIND had grown that feature, but I haven't used BIND for a while now, so maybe not. > 1b) anti spam filters believe in the magic of checking > forward/reverse match. Someone in this thread said that only malware-infested end-users are behind IP addresses with no reverse lookup. Well - no. As long as we keep telling anyone who isn't running a full-bore commercial network to "consume, be silent, die", we are holding everyone back, including ourselves. It's fine to use no-reverse-lookup as a component of a spamminess score. It's not OK to use it as proof of spamminess.
