You will need to contact your DNS hosting company and ask them to change your MX records and also add a CNAME.

Your DNS hosting company is usually your Registrar; where you purchased your domain, or the company that hosts your web site. If you are not aware of who hosts your DNS zone file, we recommend contacting the company hosting your web site.

Changing Your MX Records

You will need to change your MX records to reflect the following values:

mx01.securembox.com - 10
mx02.securembox.com - 20
mx03.securembox.com - 30
mx04.securembox.com - 40 



Please ensure that ALL domain aliases are adjusted to reflect the updated settings.
