Consider a smart host the same thing as routing mail through your ISP.
Mail servers look at the client and the client's reverse pointer. This
has nothing to do with the sender (you). Many servers (including ours)
insists on a FQDN for the sender and HELO; That is sender at do-not-
reply.notld cannot send mail to our users nor can helo=<hello-world>.
