All accounts have a default email address in the form of firstname.lastname@example.org.
Additional email addresses can be added in the cPanel using the following steps:
1) Select the “Mail” link
2) Select the option “Manage/Add/Remove Accounts”
3) This page lists all your current email accounts. To add a new account select the “Add Account” link at the bottom of the page.
4) A form will appear that will allow you to add an email address and specify the password. You can also specify the quota for the account.
The quota controls how much space the account can use up before being downloaded.
