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.

Hypervisor Upgrade, scheduled 4 years ago

The hypervisor operating system on our cluster will be updated. Due to our fully redundant infrastructure, we do not expect any downtime. As all nodes will be drained before each update, there will be a lot of live migrations which might slightly decrease the cluster performance during this maintenance window.

Cluster Cluster Performance Issues

Due to maintenance work on our cluster, performance of certain services are degraded. We will restore the usual performance as soon as possible and further investigate the root cause afterwards.

Update 11:15

Latency is still slightly higher than usual but in green range again. We'll monitor the situation closely.

Update 12:15

Latency is back to normal. We will further investigate the root cause now.
