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: Website Service: Enable ModSecurity in DetectionOnly Mode

So far, there was no web application firewall on generation 6 servers, as we had yet to lay some groundwork before. With this change, we will enable ModSecurity and load the OWASP core set, please see the detailed changes below:

  • update nginx to the latest stable version 1.14.2
  • load ModSecurity base configuration
  • load OWASP core rule set
  • enable ModSecurity in DetectionOnly mode (= logging only)
  • detected requests are logged into the ModSecurity audit log at /var/log/nginx/modsecurity.log (accessible via devop user)

Next steps:

  • we will analyze all audit logs and take appropriate actions if required
  • we might contact you over the next 2 weeks to discuss required changes on our or your end if required
  • we're going to activate blocking mode (switch engine from DetectionOnly to on) on Monday, January 28th
