How to separate IP address of your domain

How to set a separate IP address for your domain and mailserver

If you change the IP address of your domain's A record, the IP address of your mail server automatically changes as well. This happens because the standard zone template uses a CNAME record to point mail to the A record of a domain. If you wish to assign an IP address to the mailserver which is different from the IP address for the domain's A record, follow these steps:

  1. Change the MX record to mail.$domain., where $domain. represents your domain. For example, example.com. would change to mail.example.com.

  2. Change the CNAME for mail into an A record to the IP address of the mail server.

  3. Click Save.

* note Note: You must include the trailing period after mail.example.com.

To change the zone template so that all new domains will create MX records which assign your mailserver a different IP address, follow these steps:

  1. Navigate to the Edit Zone Templates scren in WHM. ( Home >> DNS Functions >> Edit Zone Templates ).

  2. Click standard.

  3. Change %domain%. IN MX 0 %domain%. to %domain%. IN MX 0 mail.%domain%.

  4. Change mail IN CNAME %domain%. to mail IN A %IP%.

  5. Click Save.

Your mailserver's IP address is now different from your domain's main A record.
