I have set up SmarterMail on a user's domain. How do they log into it?
They need to use the following login:
Password: [their control panel password at the time of adding a mail account]
In SmarterMail, with "siteadmin" you can create more users under you. If HELM created the mail account without a "siteadmin" then you would not have as much management of the mail account, because you would have no login, and you would therefore log in as a guest. As a guest you can not manage your account fully or create other users. This is why a specific admin username is chosen.
