Hello, I again have a real newbie question. As you know I deleteted the users. :(( And of course some programs need special users, so that they can run. For example postfix. How can I create a postfix user, that look-ed like this: postfix:*:1006:1006:Postfix Mail System:/var/spool/postfix:/sbin/nologin And does it need a password? Bye,
