Yes, but the message is being sent to testuser-owner at canby.k12.or.us
and the MX at canby.k12.or.us.s9a1.psmtp.com (postini ?) and that MX
doesn't know how to deliver to that address.

The problem is your list is configured with umbrella_list = Yes so all
administrative messages for member at example.com are sent to
member-owner at example.com (or whatever umbrella_member_suffix is set
