The list is not set up as a moderated list. Check DIR/editor. If should contain a ezmlm-store(1) line after the ezmlm-reject line if it is a moderated list. No ezmlm-send(1) line should be in DIR/editor. If there is, the list is not moderated. Also, DIR/modpost must exist. If it does not, ezmlm-store(1) will post the messages directly (via ezmlm-send(1)) without sending them out for moderation first. This makes it easy to temporarily remove message moderation by simply removing DIR/modpost, but may be confusing if the user is unaware of this ezmlm-store(1) feature.
