The one at Howtoforge
I have re-installed everything this evening (well, it's evening here...)
It appears the problems rise after a system update, initiated by fc10.
After this update, alle mail is rejected?
MyDNS also gets updated, it needs to be reconfigured by hand.
Re-installed the lot again.
If the update for Postfix (18.104.22.168-1) is done after the ISPC3 installation, Postfix settings are wrong.
Do not install ISPConfig 3 untill all updates/fixes are installed!
