@jimcavoli Thanks, Jim.
But it does not work that way on my setup.
On an almost duplicate setup with a different domain name the Username to open up the Email application once I click the Cloudron Mail account does NOT require the full domain.
In fact, the name I put into the Username to login does not match either the username or "Full Name".
The Username is De Boss deboss is the account name.
However to login to the Email app as the administrator the working login is "DeBoss" with no space between.
And definitely no firstname.lastname@example.org works with that password.
So now I go back to the other domain with the same setup, but setup a few days later and no combination of the email account login with its domain added "email@example.com" logins. Combo can't be verified.
So, following your advice I set up an entirely new user at this domain while logged in to Cloudron. And gave this user Superadmin privileges. It emailed a confirming invitation which I used to follow the Setup account link.
I set it up and saved and then tried to login.
The new account fails to login to the email application.
Is this Login verified from checking Cloudron servers or from my own database installed with Cloudron and the Email app installation?
When I set up Cloudron the first time it gave me one Username and password. And I continued setting up that domain with a Cloudron installation using that first Username and password.
Now I don't need to use the full domain name to log in to my Email app on that domain, just the username, although it is NOT exactly the same as what my Cloudron User account shows!
Then when I setup my second domain I had to install Cloudron again. It prompted for a new username for that account. I realized everytime I would install Cloudron in other domains that I had to use a new registration each time.
So, even though the installation said FREE if I used the green button it immediately wanted my credit card and a whole new account to be set up for a pay plan.
PLEASE CLEAR THIS UP once and for all.
What you describe does NOT work that way as far as using a full email address in my first domain, as I have described.
The second domain set up days later will not give me access to the email application with two different users following your instructions.
