Note that the hostname "lynx.northeastern.edu" has been removed(!!!) from the database held by the name-server, i.e., "helios.northeastern.edu". Thus, it **is** an invalid address. Sigh! (Had they left that name in the database, we list-owners would only be handling "unable to deliver for NNN days" messages, rather than "unknown host" error messages. Sigh!)
