I had a client report to me this morning that several of his lists mysteriously unsubscribed members of the list without their permission or interventions. As far as I can tell these members were not generating any bounces. I checked the FAQ and archives of this list but I found nothing that would explain this behavior.
Could there be any other possible reasons for this other than:
- Intentional action by member
- Intentional action by administrator
- Bounce removal
Check Mailman's subscribe log? The unsubscribes and reasons should be there.
Members with stale bounce info can be disabled (or unsubscribed if bounce_you_are_disabled_warnings = 0) if bounce_score_threshold is lowered to a value <= the member's stale bounce score.
I suppose you could add to your list 'intentional action by a third party who somehow compromised user passwords, the list admin password or the site password or found an unknown security hole'. I don't think this is likely, particularly the security hole.
