Are you saying the list is <pfenno at ncees.org> and replyers received
that bounce instead of the reply going to the list? Are they all in
the same domain? Did the bounces all come from the same MTA? which one?

Maybe. This may also be a temporary issue with your incoming MTA that
may resolve before the messages expire and they may be ultimately
delivered.

Probably nothing, but it may depend on the answers to my first set of
questions.

If in fact something has changed at their end, they probably can't do
anything about it unless they changed it in which case they should
already know what to do about it.
