Re: [Mailman-Users] Challenge/Response

Thanks for everyone's thoughts and suggestions. I have recommended setting each list on emergency moderation. They have about a dozen lists for various tasks. So, I suggested each list be assigned a moderator/administrator (Currently one person manages all lists). Since the fear is the person will
