Actually, Mailman doesn't send this mail. The Mailman 'post' wrapper
which is invoked by your MTA writes an error message 'post script,
list not found: %(listname)s' to stderr and exits with status = 1.
Your MTA is then returning an undeliverable message to the sender.
But, as Hans points out in another reply, only mail to valid list
addresses should be delivered to any Mailman wrapper in the first
