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 7/8: Filesystem Size Changes, scheduled 2 years ago

Up to now, our managed servers did use a large, virtual file system, and the actual space assigned was just a value checked within our monitoring. As this has some storage related drawbacks, we will change the behavior today. As of now, the file system size will be set to the value selected in Cockpit, plus an added buffer of 30 percent. Changes are still possible without reboot, and all tools and checks do reflect the new behavior already. We will monitor the rollout for each system carefully, and do not expect any noticeable changes apart from the new file system total size.
