No, the response are coming from the destination DSN's.

This is correct and appears to be handling it properly.

How can I configure posted messages sent to only send errors back to the
list owner or moderator? Some of the mail lists have over 2,000
participants, and do not want to flood valid posters mailboxes with
messages that cannot be delivered.

Thank you, Rose
