Title: How do I limit postings to my list so that only subscribers can post? Question: I'm trying to limit messages sent to my list so that only current members and owners can post. How do I do that? Answer: Mailman allows you to choose what to do with incoming messages. Go to your list's administration pages at: https://lists.prairienet.org/mailman/admin/listname where "listname" is replaced by the actual name of your list. Log in with your listowner password . Then click on "Privacy Options" and go to "Sender Filters." The second to last option will allow you to decide what to do with mail from non-subscribers. "Reject" and "Discard" will both prevent the mail from going to the list, but "Reject" will send a notice to the sender, whereas "Discard" will be silent.
