They may not show as having been on the list if they are subscribed under
<[log in to unmask]> or similar that forwards to <[log in to unmask]>.
The bounce from the closed MSN account is returned and of course, it's not
on the subscriber list.  You might look for <steve*@*> or check you
<*@yahoo*> and other subscriptions.  If you find a mail forwarding account
you think is the forwarding subscriber, email them, and the bounce will
give you the trail.

There is now way they are going to find them on the list if they have not,
nor are, subscribed.
