Using iRedMail-0.9.8 on a Ubuntu 16.04 Server on a MySQL backend. Using Apache2.

I've managed to get into Roundcube and this is the email that was sent to me:

Admin of domain postmaster@kimosabeit.com:

    * Account: postmaster@postmaster@kimosabeit.com
    * Password: Avendesora1970

    You can login to iRedAdmin with this account, login name is full email address.

First mail user:
    * Username: postmaster@postmaster@kimosabeit.com
    * Password: Avendesora1970
    * SMTP/IMAP auth type: login
    * Connection security: STARTTLS or SSL/TLS

    You can login to webmail with this account, login name is full email address.

So...it seems that when I try to login with the postmaster@postmaster@kimosabeit.com email address the syntax is wrong. How do I change it? Can I make a user and promote it to a global admin? I installed phpmyadmin as well to access to database.
