Manual ISPConfig installation

[Jan]

Hello HowtoForge Community,

I'm very interested in using ISPConfig. It looks just like the tool a was looking for all the time. It supports sendmail which I'm currently using in our email environment and seems to be very comfortable.
The only issue is that I don't have a fresh installed system and don't want the programs to get installed from source. I like the way that "apt-get" and the other debian tools manage the installed packages. Is there a possibility to do a manual installation?
I tried to understand the steps inside the setup, setup1 and setup2 shell-scripts but finally I gave up because it was too complex.
Maybe someone has already written a manual installation howto or a short instruction.

Have a nice weekend!

Greetings
Jan
