MX record error when sending to our mail server


We have been experiencing problems where certain people could not send mail to our server. It turned out the smtp greeting was wrong and needed to be changed from freestyle-rc.com to mail.freestyle-rc.com after doing this the same people now get the following error:

It appears that the DNS operator for freestyle-rc.com
> > has installed an invalid MX record with an IP address
> > instead of a domain name on the right hand side.

At the moment the mx record points to the ip address of our server. Do I need to change it or add a second record to point to mail.freestyle-rc.com ?


1 Solution
Yes you are correct. The other servers will do a check to match your mx record to the servers domain name, so you should set the mx record to be the same as the servers external domain name (mail.freestyle-rc.com for example).
