Listserv isn't perfect. You have a subscriber who's forwarding email
to a now-extict email address and most likely, the mailer on that system
is not returning enough information to point Listserv to the actual
address. This can be a major pain in the neck to find. Try setting your
list to "Auto-delete=No" then see what messages bounce back. That might
lead you to the particular subscription that needs to be deleted. If that
doesn't help, run a manual probe of the list.
