Comment 1 for bug 674352

> The problem is when anyone who knows the list moderator password can access and moderate the list.

That is the way it is designed to work. See, e.g., <http://wiki.list.org/x/5YA9>.

Further, the owner addresses are listed in the footer of the admin and moderator login pages, so they aren't in any way secret.

I have marked this as "wishlist" for possible inclusion in a future release.
