Hi, Anyone by any chance did sort of research if DENIED_IP_IN_*_RDNS helps his users or causes more problems? I formerly thought that this is more helpful, as IP in RDNS is most likely appear for home dsls, dialups and other stuff not supposed to run smtp server i shall trust, and if it's my users mail netline, then they shall authenticate while talkign to me anyway. But now I see that some telecoms offer dsls with static IPs (contrary to dyniamic one, rotated 24hs, that is addressed to home users) which is primarily used by companies, and therefore it's less likely for them to be spam source (due to botnes, zombies etc). I even saw a data center which named their rack hosts that way. I therefore think that it might be extremely useful to try to build a kind of database of providers who one may consider whitelisting even, they would otherwise fall into IP_IN_RDNS or IP_IN_CC_RDNS trap. Any thoughts?
