I have a list on my mailman server 2.1 called “mailman”, with no users. Is this a default list that gets created, can I delete it what is it for, it may have been created by an old admin who was testing? Also, I started getting a lot of subscription requests to this list, I think it is a bot, but not sure what it is trying to do. Anyway this got me thinking. Is there a way to setup a list to automatically discard subscription requests and NOT send a rejection notice? I could ban all domains from that list, but it is my understanding a rejection notice gets sent. We have some lists where the admin is the person who populates the list.
