[Mailman-Users] Many users unsubscribed at once (not by me)

Unfortunately, disabling automatic removal from the list will only fix 
one effect of the problem, not the problem itself. There's something 
going on which is causing mail to those addresses to bounce. If you are 
receiving messages with the subject of "Bounce action notification" 
these will tell you who is bouncing mail, and the attached mail delivery 
failure reports will tell you why they are bouncing mail, which is 
important. I suspect you have a DMARC or IP reputation issue.

Hope this helps.
