That was not the problem. I created a user "dzimmer at xxx-yyy.de" with and 
without alias and in both configuration the emails were delivered.
In my opinion the problem is: The provider appends a "delivered-to 
header" (account on the server of the provider). Fetchmail fetchs the 
mail from this account and forwards the mail to postfix. Postfix 
recognized the "delivered-to header" (local and isp account have the 
same name "dz at xxx-yyy.de") and bounces the mail. I think this is a 
design issue of the kolab-server. I have a running kolab-server since 
2002-12. All worked fine. Now i tried to install a new server (new 
hardware) and there are a lot of toubles. For this problem i have a 
workaround so i can start a new thread with the next problem now.
