DNS has been a very confusing topic for me
Anyhow I have a server with hostname server.abc.com and IP 220.127.116.11. The host names I setup on registrar for this abc.com are ns1.abc.com, ns2.abc.com
My site domain is xyz.com and I changed the nameservers of this domain to ns1.abc.com and ns2.abc.com
Now 18.104.22.168 IP is also the dedicated IP of my site xyz.com i.e. if I enter this IP in browser, it opens my site xyz.com.
Now hotmail is sending my mails in JUNK. I noticed that rDNS of my IP 22.214.171.124 is pointing to some third party server (ppp.oooo.com)
I have to correct the reverse-DNS
Now should I set the reverse-DNS for my IP 126.96.36.199 to my server hostname (server.abc.com) OR my site's domain name (xyz.com).
Btw email header of hotmail says:
Received: from server.abc.com ([188.8.131.52]) by SNT0-MC3-F41.Snt0.hotmail.com with Microsoft...........
Now I feel the reverse-DNS for my IP should point to my hostname i.e. server.abc.com but then I also fear that doing this would then point my IP (184.108.40.206) to server.abc.com, instead of my site xyz.com (like I mentioned earlier if I enter this IP in browser, it opens my site xyz.com).
I am confused like hell. Please suggest if I should do use the hostname (server.abc.com) OR my site’s domain name (xyz.com) for reverse-DNS.
Thanks in advance.
