The following Delivery Status Notification description is lifted from
RFC1893:

"      X.7.1   Delivery not authorized, message refused
"
"         The sender is not authorized to send to the destination.
"         This can be the result of per-host or per-recipient
"         filtering.  This memo does not discuss the merits of any
"         such filtering, but provides a mechanism to report such.
"         This is useful only as a permanent error.
