Basically I tried when I followed the tutorial 1st time, I ended up installing Courier and ISPConfig still showed me with POP3 Service alone as Offline, and so I reinstalled Kanotix from the begining and then started all from second time. So this time I thought I will not install the optional Courier Step to find out whether it will work out this time without Courier's involvement.
Yes, courier is optional but you wont get happy with an mbox based mailserver if you get more traffic on your server
And that's what i told you above ....
