550 is the status code, much like HTTP server responses, 2xx is
successful, 5xx is usually bad. In this case, 5xx means "Do not try
again, this error was fatal". 4xx errors on the other hand mean "Could
not deliver the mail right now, so try again later". Most sending MTAs
are configured to retry on default for a week before finally giving up.
