It is possible to "subscribe" to a list and set that address to "nomail". So, this participant can still send messages to the list but will not receive anything. Much better idea than manually going through all the messages held for moderation. Christian -- Christian F.

Check the message headers -- there might be common patterns. Look for Received: headers with "unknown" -- this is a giveaway that the messages are using spoofed From: headers. Also look at the From: address, sometimes these messages are coming from partitular domains. There are spam filters and sender filters. When the regexp matches, one option is to *silently* discard the message. *If* you have access to the inbound MTA's configuration, there are things there that can drop or bounce the messages at that point. > > Ken Gordon > -- > Mailman-Users mailing list Mailman-Users@python.org > https://mail.python.org/mailman/listinfo/mailman-users > Mailman FAQ: http://wiki.list.org/x/AgA3 > Security Policy: http://wiki.list.org/x/QIA9 > Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ > Unsubscribe: > https://mail.python.org/mailman/options/mailman-users/heller%40deepsoft.com > > -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org

If it is a few known addresses, you can add them to accept these non-members to white list. If you want to accept some non-member but reject others, unless you can devise a filter to distinguish, you need to review them all. -- Richard Damon -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
Re: [Mailman-Users] Nonsubscribers attacking one of my lists.
Set the action on Sender Filters for messages from non-members to discard, instead of hold. I had to do that a long time ago (Don’t reject or you will be generating back-scatter) > On Jan 19, 2019, at 4:58 PM, Kenneth G.
