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?
