I'm in the middle of launching a new website for an already-in-use domain. The domain has a complicated email system so we'd like to move that over to the new server a bit later on.

Currently the domain DNS is managed by the current webhost. I plan on moving the DNS management back to Network Solutions, then point the A record to the new website's IP. However, currently the DNS has the MX record the same as the A record.

When NetworkSolutions is managing the DNS, and I point the A record to the new IP, then the MX record can't be the A record..

Right now: A Record mydomain.com points to IP address MX record mydomain.com points to IP address

What I want: A Record mydomain.com points to IP address of new server MX record somehow points to current existing mailserver

Does this even make sense?


Can you not do (pseudo)...

example.org.      IN  A
mail.example.org. IN  A
                  IN  MX mail.example.org.


  • Are you saying that I set up A records for WWW, @ and Mail. Then mail.mydomain.com points to the old IP? Then set up MX record to point to mail.mydomain.com? Will this be enough to not disrupt the existing users and email? – Preserved Dec 10 '12 at 22:17
  • That's another way of doing it and is totally valid. – joeqwerty Dec 10 '12 at 22:37
  • @Preserved, there may be a period where cached DNS records prevent you from sending/receiving -- if you want to do it without outage, we're going to need you to clarify your question: who runs the mail server, who runs the web servers, what are their (anonymised) IPs and what DNS records already exist for this? – jimbobmcgee Dec 11 '12 at 12:26

I always have trouble following what's being asked in these DNS questions, but to cut to the chase: The MX record doesn't have to point to a server in the same domain. It most certainly can point to a server in another domain. In the NetSol DNS control panel go to the "Add/Edit Mail Servers (MX Records)" section and add the FQDN of the current email server.
