Hi I was wondering if it is possible to do the Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Fedora 10) tutorial after completing the Perfect Server tutorial for Fedora 10 (minus ISPconfig). E.g. Postfix is set up via yum in the Perfect Server tutorial however the Virtual Users and Domains... tutorial uses rpm. What do I have to do before I follow the Virtual Users... tutorial in this case if that is possible? Do I have to uninstall Postfix, Dovecot or more packages?? Do I have to start over?? (hope not) Help would be appreciated, as you can guess I am a newbie.
