I thought that the domain is in the list of accepted domains when I  
add it to the list of domains in the kolab webadmin?

What I do not understand is the following. My kolab server is  
responsible for my business domain as well as my private domain. So I  
need to send emails using email addresses from both domains through  
the same kolab server. The alias setting in the virtual file does not  
work as described. But when I explicitely add  
carsten at myprivatedomain.com as an alias entry to my user (which has  
the email-address carsten at mybusinessdomain.com) it works. Looking at  
the configuration it seems that both ways work through an alias  
configuration. But where is the difference?
