If you want to use a mobile application compatible with JMAP, it will ask you for the connection URL of the JMAP server for your mailbox.
To find the JMAP connection URL:
Log in to your user space on [https://mail.ecomail.earth/login](https://mail.ecomail.earth/login)
Click on the 4 squares at the top right of the interface
Click on "My Account Settings"
Next to "Main Settings," click on "Access"

At the bottom of the page, the JMAP settings are displayed.
