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: allow outgoing connections to common services by default, scheduled 6 years ago

By now, all outgoing connections where disabled on any server. To connect to the outside world, you had to use our central proxy server for HTTP connections or add appropriate firewall rules manually to allow any other connection. As this configuration requires a deep understanding of networking technologies, it has led to frequent problems due to missing or wrong settings.

As of now, we will therefore enable direct outgoing connections to the following services by default:

  • HTTP(S): TCP Ports 80, 443
  • SMTP(S): TCP Ports 25, 587, 465
  • POP3(S): TCP Ports 110, 995
  • IMAP(S): TCP Ports 143, 993

This rules apply to generation 6 servers only and will cover most outgoing services required out of the box. For any other outgoing connection required, you still have to add manual rules as described in our documentation.

Related to this change, we also updated the corresponding documentation to reflect those new default settings.

Hint: This change might not apply to your company if you or your supervisor decided to keep the old behavior in place. If in doubt, please ask internally or contact us directly for more information.
