Getting blocked by GoDaddy for rDNS

[schase]

Howdy,

Not sure how to resolve this problem. I spent some time on the phone with them today and they couldn't tell me what they needed.

My setup is: SBS2000, I run a 3rd party email. the SBS is of course also AD, with DNS on it. We host a few company websites. Those domain names are different from the company's network domain name.

Server named like : server.mynetwork.com

One of the web domains would be like:

http://www.hosteddomain.com

I send an email from hosteddomain.com to someone hosted by godaddy. Godaddy rejects the email saying it is a badly configured rDNS as hosteddomain.com's ip address resolves back to server.mynetwork.com

and they refuse to let it unblock.

hosteddomain.com has dns like this
A 123.45.67.89
MX 10 mail.hosteddomain.com.
mail A 123.45.67.89

123.45.67.89 (for example) is the pub ip address for server.mynetwork.com

what do I need to do to allow my ip address to resolve back to mail.hosteddomain.com - is it to just add ptr records for each and every domain we host on the same server?

Thank you in advance.

You need to contact you ISP and have them add the rDNS record that resolves back to your MX record. In other words, your external mail server (outside) IP address must resolve to the MX record where your public DNS records are hosted.

Hope This Helps,

Good Luck!

thanks, but no the rDNS resolves back to my servername just fine.

It's the different website domain name that doesnt match to the server's network name that's causing the headache.
