One reminder here -- whether setting up the reverse DNS entries on your own
DNS server, or an outsourced DNS server such as zoneedit.com, you still
*must* get your ISP or bandwidth provider to handle things on their end, or
you won't end up with a reverse DNS entry.
Of all cases I've seen where a reverse DNS entry didn't exist, I would say
that about 75% of the time the admin *thought* it did exist ("My DNS server
has a reverse DNS entry listed in it, and my example.com domain works just
fine"). Then, they "prove" it by saying "If I type 'tracert
xxx.xxx.xxx.xxx' from the local network, it shows the reverse DNS entry'
(since the local network typically uses the local DNS server, it will see
the reverse DNS entry).
I would strongly urge people (even the person who posted the recommendation
for zoneedit.com) who think that they have a reverse DNS entry set up to
verify that they do. One way is through our http://www.DNSstuff.com site,
using the "Reverse DNS Lookup" tool. You may be surprised to find out that
there really is no reverse DNS entry. Remember, the key is that your ISP
or bandwidth provider (whoever originally gave you your IP address)
absolutely, positively must take some action for the reverse DNS entry to
work -- there is no way around that. And, in many cases, the ISP makes a
mistake (as someone reported earlier today), so you still need to
double-check their work.
