Mailinabox has deactivated apache2! When I received the warning, I canceled the installation. Apache2 is not running. How to reactivate?
Mail-in-a-Box is meant to only be installed on a new virtual machine with nothing else running on it. If you need to reverse Mail-in-a-Box actions, you should read through the setup scripts and check each action one by one to determine what you need to do to undo it.
Danke für den Tipp!
sudo ufw default allow incoming
sudo ufw default allow outgoing
Hat den Fehler behoben!
