Not quite. GNU Mailman comes with nice features to ease this task. You can configure it so that everyone who is currently subscribed can post freely, but new subscribers get a "moderated" bit set on them. The first time this new subscriber attempts to post to the list, a human moderator has to inspect their message and decide whether to approve it or deny it. If they human moderator approves it, they can also on the same web form remove the "moderated" bit from that poster. Therefore, the volunteer work required would be inspecting the *first* post from each *new* subscriber to see if that post is spam.
