We will update Mailcow from legacy to the newest master version, which contains the following breaking changes:
Users log in as usual at the following URL: https://mail.example.com/
Domain administrators now use https://mail.example.com/domainadmin
Administrators use https://mail.example.com/admin
The SOGo web interface is now only accessible via the user login at https://mail.example.com/; after a standard direct redirect to SOGo, the Mailcow settings are still accessible via the link (wrench icon, top right). The Login URL for Roundcube User does not change.
Take a close look at the changes, update your documentation accordingly, and feel free to contact us at any time if you have any questions or concerns.
