But those were smtp servers, so I don't see you the OP could
have accomplished his goal unless you set the wayback machine
to pre-Internet days and use the uucp transport mechanism.

That local ISP server is also an smtp server.  I haven't heard
of anybody accepting vail via uucp for at least 10 years.  I'm
not saying that such hosts don't exist, but that they're pretty
