Foreign members of a group

[Christian Tardif]

Previously, on Kolab 2.x, we were able, in a group, to add a user with a 
foreign email address by first entering it into the Global Address Book. 
In the new Kolab environment, with Multi-Domain, how can achieve this?  
For example, I may want to have abuse at thisgroup.tld which, in fact, will 
receive mail and send it to complain at thistopdomain.tld. I would not have 
to create an entry into every particular domain where I want this to be 
available (which does not even seem to be possible in Kolab 3 Webadmin 
anyway).

Simply said, how can we have distribution list that sends a mail outside 
of the target domain?
