Once you’ve set up your account with Google, you can then add the MX entries needed through your cPanel. To do this, follow these steps:
Go to the ‘MX Entry’ icon under cPanel’s mail section. Then enter the first of the MX entries needed and click Change. Next click on ‘go back’ and enter the next MX record and then click “Change again”, which will add a new MX entry. Continue this until all the MX records you need are added. You will also need to delete the original MX record which points to your own domain name with priority 0. Finally, under the “Always Accept” column at the bottom, click on “Set to No”.
Here is the list of MX entries you need to add:
