I followed the SUSE perfect setup 10.1 with ISPconfig and everything works fine. I understand postfix was installed during this installation but I'm a little lost on how to manage the mail. Is there a web app to setup and manage the emails for my domains or did I miss something in ISPconfig?
ISpconfig manages the mail for you. In ISPConfig you can add the email addresses / users on the user & Email tab of the website settings.
