John, 

 

I wouldn't go as far as saying no Domain registrar supports PTR records.
Let me show you:

 

autosoldnow.com on Network Solutions:

 

(FAIL) Reverse DNS entries for MX records

 

ERROR: The IP of one or more of your mail server(s) have no reverse DNS
(PTR) entries (if you see "Timeout" below, it may mean that your DNS
servers did not respond fast enough). RFC1912
<http://www.DNSstuff.com/pages/rfc1912.htm>  2.1 says you should have a
reverse DNS for all your mail servers. It is strongly urged that you
have them, as many mail servers will not accept mail from mail servers
with no reverse DNS entry. You can double-check using the 'Reverse DNS
Lookup' tool at the DNSstuff <http://www.DNSstuff.com>  site (it
contacts your servers in real time; the reverse DNS lookups in the DNS
report use our local caching DNS server). The problem MX records are:
19.15.69.67.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0)
(check it <http://www.dnsstuff.com/tools/ptr.ch?ip=67.69.15.19> )]

 

 

Smoothrunnings.ca on Register.com:

 

(PASS) Reverse DNS entries for MX records

 

OK. The IPs of all of your mail server(s) have reverse DNS (PTR)
entries. RFC1912 <http://www.DNSstuff.com/pages/rfc1912.htm>  2.1 says
you should have a reverse DNS for all your mail servers. It is strongly
urged that you have them, as many mail servers will not accept mail from
mail servers with no reverse DNS entry. Note that this information is
cached, so if you changed it recently, it will not be reflected here
(see the www.DNSstuff.com Reverse DNS Tool for the current data). The
reverse DNS entries are: 108.138.248.206.in-addr.arpa
206-248-138-108.dsl.teksavvy.com. [TTL=3600]

 

Regards,

Andrew

Once again Andrew, you are incorrect. No Domain name registrar supports
PTR records for a very valid reason; PTR records can only be created by
the entity that controls the IP address, of which no Domain registrar
does.
