Hello all, Seems that some config setting in ISPConfig 2 need to be changed. But where? I've installed the ISPConfig 2 some time ago, following this HowTo: http://howtoforge.com/perfect-server-ubuntu8.04-lts I've installed RoundCube as the web mail client. As I would like to use the webmail directly without logging in to the ISPConfig, I just enter the URL: http://www.mydomain.com:81/roundcubemail But this gives me an error message in the browser: "Firefox can't establish a connection to the server at www.xyz.de:81" I remember that I entered that particular URL somewhere during the ISPConfig installation. But how do I change it to use my domain instead of xyz.de ?
