[Mailman-Users] Lists not Sending

[Tom Noise]

I'm running into a problem today with posting and receiving through lists.
This morning posts to the list were being sent and received fine, and now
the posts are being sent through the email client correctly (I checked with
a non-list email address), but nothing is being posted to the list. I've
been back through the settings and nothing seems to be off on the list.
Nothing is in the archives, and nothing is being held for moderation.

Thanks.

Tom
