How to Configure Google Mail With Your Domain

Gmail has a built-in functionality that allows you to check emails from external accounts using the POP3 email protocol.

You can configure your email accounts in your Gmail interface by following the steps below:

Sign in to your Gmail Account.
Choose Settings, from the Settings tab
Go to Accounts and Import
Under the section Check mail from other accounts choose Add a mail account
Enter your Email address (e.g. user@yourdomainname.com)
Click the Next button
Username: enter your full email address (e.g. user@yourdomainname.com)
Password: you should place the password for the above email address
POP Server: Your Secure SSL/TLS server settings are listed in cPanel -> Email Accounts -> More -> Configure Email Client
POP3 port: 995
Leave a copy of retrieved message on the server can be selected if you wish to save your messages on the servers as well
Always use a secure connection (SSL) when retrieving mail needs to be checked
Click on Add Account

You can continue with the SMTP server setup if you wish to send mail from your email address:

Select Yes, I want to be able to send mail as user@yourdomainname.com
Choose if you will use this address as an Alias
SMTP server: Use the same secure server as you did in the incoming settings configuration
SMTP port: 465
Username: enter your full email address (e.g. user@yourdomainname.com)
Password: the password for this email account
Check the Secured connection using SSL option as well
Click on Add account

Gmail will send you a verification email that you have to approve, so you can use the SMTP functionality.
