Hey Falko and Till,
I have it working finally on my install of CentOS. I have had quite a few compliments on it, it is at http://www.hosthobo.com
. It is working like a champ except the DNS is not quite working the way I thought it would. I tried using falkos howto for dns and then backup with someone like dyndns.com but to no avail for some reason dns just won't do it's job. I am still working on it so not a big deal. However everything else is working perfectly as long as I set my DNS up somewhere else. I also added Bazzer's Server Status Monitor to the website and it is actually monitoring the http, smtp, pop3, mysql and sc protocols. I tested it by taking down all but the http and it worked like a champ also.
By the way I am using latest version with the bug fixes as well. Great Job thanks for the great project / software.
Have a great one.
