Usually I would have said that you can use a transports entry for
these users or create Kolab accounts with a fake kolabHomeServer
entry pointing to the non-Kolab server, but for all this the Kolab
server has to be able to communicate with the second server on port
25.

But how do you think the mail should be passed to the other side if
the second server isn't reachable from the first?
