MX records for mail server
Posted on 2009-04-14
I'm pretty new to DNS, so please bear with me. I've just bought a VPS package for hosting a couple of websites. I've found that my server comes with MailEnable mail server, so I would like to manage the mail for the websites too.
I want to ensure my DNS information has been set up correctly. I have set up the following domains and DNS information:
Type - Domain - Type - Target
A - mydomain.com - 18.104.22.168
A - mydomain.co.uk - 22.214.171.124
MX - mydomain.com - mail.mydomain.co.uk
MX - mydomain.co.uk - mail.mydomain.co.uk
A - mail.mydomain.co.uk - 126.96.36.199
Reverse DNS for 188.8.131.52
My question is, for my mail server to work correctly, do I need to change the PTR record servername.mydomain.co.uk to be mail.mydomain.co.uk? Or do I need to create an A record for IP 184.108.40.206 to point to servername.mydomain.co.uk? Does this general setup look solid or seeing as though I am using the .co.uk domain as the main one, should hte .com be a CNAME to the .co.uk version?
Thanks very much for your help.
