Several entities within the University maintain lists to which subscription is,
in essence, mandatory. I have been explicitly asked whether it is technically
possible to prevent subscribers from leaving these lists. Has anyone implemented
a list exit to either prevent signoff or require owner approval for signoff?

I am not interested in flames and rants attempting to educate me that this is
not "A Good Thing". I manage the University's central email service, including
the list service, and I am already well aware of the potential problems.
