An open relay is an email server that will forward mail from any address
to any address.  What you describe above is not an open relay.  A non-open
(closed?) relay will accept incoming mail from any address (assuming no
other restrictions) that is destined for the domain that the server
serves.  It will not accept incoming mail for domains not under its
jurisdiction.  If what you said above were true we couldn't send mail to
each other.

Man I hope I got that right :)
