E-Mail Client Configuration


E-mail can be accessed through webmail or from a desktop/mobile client such as Outlook, Thunderbird, K9 or Mail.

Login Credentials

Your login will always be in the form of user@domain for e-mail. 

Example: If your domain is and your username myadmin, then the e-mail login is  and not  myadmin.
Your password is the same password that is used to log into the control panel.
