Lee is correct, there is no consensus. :) However, as far as I can tell everyone insisting that PTR is important is arguing that the world would be a better place if every endpoint on the Internet was equal. The main argument seems to be that because e-mail uses reverse DNS as input into spam detection, it is important. The argument proceeds to then say that we want every computer on the Internet to run an SMTP server, so every computer needs a PTR record. This reminds me of the late 20th century/early 21st century IETF, when it was filled with anti-NAT rage. This dedication to the pure end-to-end principle resulted in broken protocols which allowed closed solutions like Skype to dominate. Network operators don't block port 25 because they want to sell e-mail service. They do it because they end up originating spam otherwise. Their networks get blackholed then. This seems perfectly pragmatic to me. Anyone who wants to run a mail server can get their own VPS more cheap than their home Internet connection so it doesn't seem like a huge problem. I know I won't convince anyone, so really this is just a rage post. I apologize, but somehow couldn't stop myself.
