You can add email accounts from within your cPanel control panel. Here are some quick steps to get this done:
Log into your Name.com account, then select go to the Hosting Services page and click the Hosting Dashboard button.
Once logged into your cPanel select Email Accounts under the Mail tab.
On the Email Accounts page you can add accounts by filling in the Email and Password (twice!) fields and clicking Create Account.
On this same page you can find connection information for you POP3 and IMAP clients by clicking More next to the account you would like to connect to and selecting Configure Email Client. Or you can get your email using the webmail interface by visiting http://yourdomain.com/webmail in a browser.
