[Mailman-Users] Moderation and Uncaught Bounce messages not being sent

[Christopher Hatty]

Our mailman server stopped sending out the following notifications:

Uncaught Bounce notifications
Notification a sender gets when a post has been moderated
Notifications to moderators and list admins of any kind

I have NO idea what might have precipitated this. I'm not even sure when it
happened.

Can someone start me in a direction toward finding out?

Thanks
Christopher
