To create an email account:

  1. Log into cPanel. (Use yourdomain.com/cpanel)
  2. In the Mail section, click Email Accounts.
  3. In the Email field, type the name you want and select the domain name from the adjacent drop-down menu.
  4. In the Password fields, type the desired password twice. Alternately, you can use the Generator to create a secure password. Make sure you copy it and store it in a safe place.
  5. Make a selection for Mailbox Quota.
  6. 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.
