First things first
You will need a basic user account.
After this, you can request E-Mail domain access.

How the user accounts work
We have set up the user accounts to work a little differently, your username can be tied to multiple E-Mail domains, which essentially means "1 account per domain".

1. Authentication: username
This works as a catch-all for your account, if you have access to one or multiple e-mail domains, any mail addressed to you will be fetched if you only authenticate with your username and password.

2. Authentication: username@domain.tld
This works as your "mailbox", if you authenticate with you username@domain.tld and password, you will only receive mail addressed to this e-mail address.
