First of all, his bounce proccessing is too strict. He has bounce_score_threshold <= 1 and bounce_you_are_disabled_warnings = 0 so the member is removed on the first bounce. There also appears to be some kind of SMTP delivery problem causing intermittent bounces. Check your MTA logs and Mailman's smtp-failure log to see if you can determine what's happening. The puzzle is how does the same address keep getting re-subscribed so it can be unsubscribed again. One curious thing about the above subscribe log entries: they occur at 15 minute intervals, which is normal for BounceRunner bounce queue processing, but each one has a different PID. Could it be that BounceRunner is dying and restarting each time? Check Mailman's error and qrunner logs. Maybe what I say about settings above isn't it at all. Maybe there are people at the threshold, and some processing glitch which prevents the runner from saving the list after the unsubscribe. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
