From reading the above paragraph, I'd say that companies selling Kolab
services might also fall within the range of the definition.
It is not entirely clear.

IMO we should disable use of spamhaus by default because Kolab Server being a
Free Software product, it must be possible to resell it commercially.
Even when this is only a configuration, I believe the default configuration
should be kept within such a clause.
