Just hoping to get a consensus on this. Postfix is stating that a host
(in fact several hosts from the same ISP) does not have rDNS, because
our DNS (Bind 9.8) returns SERVFAIL when looking up a PTR record for it.
The IP in question is 63.171.0.212. From my perspective, this IP does
not have a PTR record and as such does not have proper rDNS. Other tools
(including older versions of bind) might say otherwise; What do you say?
