Register.com doesn't support reverse DNS 2

[cY2k]

We have our company's domain and website through register.com, and unfortunately, they have told me that they do not support reverse DNS. Which basically makes it so that we cannot send email to anyone "@aol.com" and a few others. My question is this: is there any way around this? Is there some other way to get reverse DNS listed for a certain domain, if your webhosting company does not support it?

Thanks in advance.

The responsibility for reverse DNS lies with the organisation that you get your IP addresses from, usually your ISP. If you don't get your actual internet connectivity from them then they are not responsible for your reverse DNS. What is the IP address of your outgoing mail server?

Okay, then that would be Verizon, since we have our T1 through them... Here's the IP: 216 dot 105 dot 111 dot 26

Okay,

; QUESTION SECTION:
;26.111.105.216.in-addr.arpa. IN PTR

;; AUTHORITY SECTION:
111.105.216.in-addr.arpa. 3600 IN SOA ns1.savvy.net. dnsadmin.savvy.net. 12 900 600 86400 3600

So the reverse DNS responsibilty for that IP address is with Savvy so they need to do the reverse. You should be able to request this through your ISP.

You will also need to have a matching A record that resolves to that IP address so that the forward and reverse match. You should arrange to have an A record created through register.com. Anything will do, some like mail.yourdomain.com.

When you send mail to AOL they will do a 'double reverse lookup'. This means that they will check the PTR for your IP address and then look up that host name to make sure that it resolves back to the original IP address.

I've just checked, you already have an A record in place for your MX record so just have the PTR pointed to mail.snsfire.com.
