Will something like this work?

[Dean Hollister]

site me
         groups *
         reject groups "apana" path "uni-berlin.de"
         reject groups "apana" path "wa.nnrp.telstra.net"

Or do I need to go about this another way? As the entries suggest, I want 
to block the acceptance of any APANA groups that contain the above path lines.

Regards,
