I have about a dozen users, I have no clue what lists my users subscribe to, and I really don't want to waste time figuring it out. When Steve mentioned the well known fixes for mailing lists, I assume he meant a shim in front of the list or maybe a a configuration option to reject incoming mail that has a policy other than p=none, thereby protect list users from getting bounced off the list by malicious senders. That's what I'm doing on my lists.
