[Kolab3] auto-created folders and addresses

[Henne Holly]

Hi,

I have some domains, say domain.de and domain.com which are configured 
as kolab-served domains. Mail gets delivered properly to user at domain.com 
and user at domain.de if the user holds those addresses as alias or mail 
property in ldap, though it's mailHost property is set to localhost and 
the mailbox is hold by cyrus as user/user at domain.de by default. So far 
so good.

Now I want to some addresses (e.g. user at domain.de AND user at domain.com) 
to be auto-generated by kolab. I have one section [domain.de] in 
kolab.conf which seems to apply to my user with "mailHost: localhost".

My question is: How does kolab know which users to serve? If I created a 
section [domain.com] would this be also applied to all my users? Is this 
just some DNS-resolving thing I have to set locally in /etc/hosts?

sincerly,
Henning
