Restricions on Distributiongroups

Hi!

We have a number of Distributiongroups called 'auto*something*' and we want all users not to be able to use these groups directly.

However, these auto* groups are member of ordinary distributiongroups which users may use and send to.

I've looked through all parameters on set-distributiongroup but can't find anything that solves my problem.

Does anyone have a solution for this problem?

Thanks!
