Mailcow important changes for update from legacy to master

We will update Mailcow from legacy to the newest master version, which contains the following breaking changes:

  1. Login With the update, the login screens for users, domain administrators, and administrators are now separate:

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.

  1. Two-factor authentication (2FA) Users/mail accounts that have 2FA enabled must now use app passwords to log in via mail protocols such as SMTP/IMAP, etc., for example when using a local email client or the Roundcube web interface. Each user can create these after logging into their Mailcow account under "App Passwords".

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.

Managed Server Version 6: Introduce netdata system monitoring, scheduled 6 years ago

With this change, we introduce a new way to monitor your servers load through Netdata. Netdata is a interactive, realtime web dashboard running on each server. You can reach its webinterface at http://localhost:19999.

To connect from your local computer, either forward port 19999 through SSH (ssh <hostname> -L 19999:localhost:19999), or add a reverse proxy website forwarding requests to http://localhost:19999 (make sure to enable HTTPS and password protection).

In a next step, we will collect those metrics centrally to have them available through cockpit.
