If you have lost your email password and cannot log in to check email from your domain, you may log into your Control Panel and reset your password. You do not need the original password of your email account in order to do this. You only need your Control Panel username and password.
Log into your Control Panel via a link like this:
http://yourdomain.com:2083 (replace yourdomain.com with your own unique domain name)
Click the Email Setup button, and view the list of current email accounts setup for your domain. Locate the appropriate email address under the POP3 email accounts, and click the “Set Password” link. You will be prompted to enter your new desired password. Please save your new password and write it down for storage in a safe place, so that you can refer to it in the future.
