Scheduled Maintenance
Migrate Mail-Relay

We will migrate our Mail-Relay to a new server.

  • This affects only a small fraction of managed-servers where that are explicitely configured to use this mail-relay for outbound mail
  • Since we migrate the IP address, there is no need for any configuration change on the managed-servers that send mail via this relay server
  • During the migration the system will be unavailable for a short period of approximately 5 to 10min

Cluster Maintenance

We will update soft- and firmware throughout our cluster. During the update, a higher disk i/o latency is to be expected.

Migration Recursive DNS Resolver Servers

We will migrate our recursive DNS resolver servers to a recent version on new servers.

The servers will keep their IP-Addresses and therefore no configuration change on systems relying on those name-servers for DNS lookups is needed.

We don't expect this change to cause any harm (due to having a redundant pair of nameservers), for the sake of safety we perform the switch-over during our maintenance-window.

This change only affects recursive DNS resolution. Our authoritative DNS servers (name servers) used for domains are not affected.

Mailcow important changes for update from legacy to master, scheduled 5 months ago

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.
