That's not true at all.
What I require is that IFF you have reverse DNS then it must be correct
and complete, else I may believe you're spoofing your hostname.
Broken reverse DNS is worse than no reverse DNS at all.
Use the latest version of host with '-v -A' to verify your hostnames and
reverse DNS are orthogonal and complete.

Actually it's required by the RFCs and BCPs.

Of course -- this is a "lame client" reject, not a recipient address
reject.

On that we agree 100%! :-)
