Great, so it looks like it's set up correctly. I was testing it with a few
public reverse-dns lookup tools yesterday, (e.g
http://postmaster.aol.com/cgi-bin/plugh/rdns.pl) and no PTRs were being
found.

At the same time, DIG returned the correct info when I queried my NS
directly...I have the feeling my upstream's NS was at fault, because
everything's working now :(
