I've just seen that ISPConfig 3 Beta supports virutal users. I suppose with this new version the spam problem reciving mail for system users like email@example.com
are solved, right?
What about using ISPConfig 3 Beta produktiv and how to migrate from ISPConfig 2 to ISPConfig 3 Beta?
Still I woult be lucy to get some anwsers to my question in my previous post :-)
