Select the Mail drop-down menu and click on Forwarding
Click the plus icon to add a new Mail Server Forwarding Instance.
Add the information for your mail server and domain that you are adding it for. If your domain uses DNS services through DNS Made Easy you can click the checkbox to automatically add the required MX records to your DNS configuration. Otherwise, they will need to be added manually.
Step 2: Adding the MX records on a different DNS Provider (only if needed)
If your domain is not managed within DNS Made Easy you will need to record the MX records to add to your DNS configuration, click on the “Information” icon under “Mail Servers” to view the MX records.
