I believe that the list can be set to acknowledge receipt to the
poster.

If you want the poster to get acks from each recipient individually,
it can be done, but AFAIK (a) you have to modify the Mailman code and
(b) bounce processing becomes the responsibility of the poster,
because "sender" is where many (most) software will send error
notices, regardless of other settings.
