1. What auto-discards spam is our "listhelper" setup. Description: http://listhelper.nongnu.org.
2. admin_immed_notify must be set to yes for listhelper to function at all. If you set it to no, no spam will be automatically discarded. 3. It is unfortunately not possible to auto-discard spam based on scores via mailman web ui options, as far as I know. Mailman has no concept of (spam) scores. 4. To avoid seeing the flood of notifications, I suggest filtering in your mail reader. E.g., my .procmailrc recipes (except I don't actually send them to /dev/null; any filename is fine, relative to ~): # _ is used instead of space when the Subject: line is encoded :(. :0 : mylock-mmreq * ^Subject: (=\?utf-8\?q\?)?[-_a-zA-Z0-9]+[ _]post[ _]from /dev/null # :0 : mylock-mmconfirm * ^Subject: confirm [0-9af]+$ /dev/null Personally I have one way to avoid the daily message as well (otherwise I would get hundreds of them), which you may or may not want: :0 : mylock-mmwaiting * ^Subject: .*[ _]moderator[ _]request.*[ _]wa /dev/null Hope this helps, Karl
