How Do I Create Email Accounts in cPanel?
By default, you have no email account set up. The main username may look like it is setup as an email, but if you wish to use it, you will need to add it as an email account. To create an email account:
Log into cPanel. In the Mail section, click Email Accounts. In the Email field, type the name you want and select the domain name from the adjacent drop-down menu. Note: The email name shadow is reserved and cannot be used for an email address. In the Password fields, type the desired password twice. Make a selection for Mailbox Quota. Click Create Account.
The same steps work for creating email accounts for your primary domain, addon domains and subdomains. You cannot create email accounts with a script or via SSH.>
