[Mailman-Users] Massive Reduction in Subscribers?

[Hunter Hillegas]

I got a report from a list owner for a list we host... He says his list
membership count went from 32,000 to 25,000 'over a couple of days'. He
obviously thinks this is strange...

Of course, it is possible that a lot of people simply unsubscribed.

I guess it could also be something else... Do bounces ever cause
unsubscription, not just blocking? Would there be something else? It does
seem strange to lose that many members so quickly.

Any pointers to figure out where these folks went would be great.

Cheers,
Hunter
