Hostname in SMTP greeting
So I'm one of those weird people that can run a webserver with the best of them, but chokes on DNS issues. I've just never concerned myself much with that side of it, so for the purposes of this particular problem, feel free to talk to me like a child. I'd appreciate the help either way ;)
I'm using dnsqueries.com to try to perfect my server. Here's what I'm getting:
Code:
The configuration of your mail servers and your DNS are not ok! The report of the test is:
mail.mydomain.org. -> server.mydomain.org -> main.ip.of.server -> main-ip-of-server.hostnoc.net
mydomain.org. -> server.mydomain.org -> main.ip.of.server -> main-ip-of-server.hostnoc.net
Spam recognition software and RFC821 4.3 (also RFC2821 4.3.1) state that the hostname given in the SMTP greeting MUST have an A record pointing back to the same server.
(edited out domain, not exactly thrilled for it to be seen in it's current state)
While I can almost wrap my head around what it's saying, I can't seem to wrap my head around what I need to do. My domain is registered at GoDaddy, pointing to my VPS. So I'm editing half my information in WHM and half at good old GoDaddy, and my brain just isn't processing this well today. Would anyone be kind enough to offer me some advice?
