Multi Domain Setup Kolab 3.1

[User, Kolab]

Hi folks,

> Webadmin, can you select your domain in the upper right corner?

Thanks a lot Timotheus, that really helped! I tried to find the new 
domain within the user form. A completely new domain within a new ldap 
tree is allright now...

But I am still struggeling with Alias Domains.
If I edit a domain it looks like:

domain1.tld
sub.domain1.tld
localhost.localdomain
localhost

I added domain2.tld

Next I edited a User of domain1.tld and added user1 at domain2.tld as 
secondary email adress.
When I try to save the changes Kolab shows up an error: Alias 
'user1 at domain2.tld' must be configured manually for 'user1 at domain1.tld'.

Does anybody have a solution?
Thanks a lot!
