@nebulon because the USER doesn't have a clue. It's the ADMIN that is guiding this process and has to send the info to the USER.
The Admin is the one who sets up the mailbox and has the responsibility to notify the user of how to use it.
Not the other way around 😆
So please make it EASY for Admins to let the users know how to set up Email.
Email the Cloudron user the info as soon as the mailbox is created Copy the details easily so it can be pasted to the user if requested.
