[Mailman-Users] 25,000 unsubscribes in 4 hrs

[Dan Sherbondy]

Over a month ago I used mailman for a 100,000 mailing.
 
Yesterday, in a 4 hour span, I received 25,000 unsubscribe notifications
such as "lupetherealtor at yahoo.com has been removed from TopCARealtors"

I normally received 100 unsubscribes per mailing so I think something is
wrong and dont want to remove these people from my list unless they
really unsubscribed.

Is the unsubscribe notice used for bad addresses as well as
unsubscribes?

Any other thoughts?

 

Thanks,
