Problem solved.

The Problem:
FreeBSD by default sends out report emails for daily/weekly/... cron job 
results. These emails are, according to /etc/aliases sent to the user "root". 
Since Kolab2 is running an SMTP server on port 25, this SMTP server is used. 
And because Kolab2 (this one here at least) has configured a smart/relayhost 
the email ends up being sent to that smart/relayhost because kolab2 does not 
detect the domain to be its own - since the host name itself (kolab) is as 
well included.

The solution:
rather simple, just edit /etc/aliases and set a reasonable alias for the root 
user (first alias, commented out by default). After that, you have to 
run /usr/bin/newaliases  (NOT /kolab/sbin/newaliases)

It might take a couple of minutes (or even half an hour) until all changes 
have taken effect (for example if leftover mails with a wrong header are 
still around).
