We are using Mailman 2.15 and have an unusual problem that I was hoping
that someone can help me with. We have close to 109 lists running
successfully, however there are times when bounce processing sends the
following message (over 100 times) in the span of a few hours to one
user/subscriber to the list. They are not the admin:
This is a Mailman mailing list bounce action notice:
Action: Subscription disabled.
Reason: Excessive or fatal bounces.
The triggering bounce notice is attached below.

(reason: 550 Host unknown)
I understand why a user would get this message if they exceeded their
threshold, but why are over 100 of the same messages being sent to one
