Here is a suggestion:

The Kolab interface can have a section about using RBL/spamhaus,
but no button to activate it. Instead the section reffert to a script to run.
The script change the status of a flag in k=kolab object.
The admin interface must display the satus of this flag in the RBL section.

That way the use of RBL is a voluntary action of the user!
