be careful of this setup.  You can turn on an open relay if your not
configured correctly.

Originator -> SMTP1 -> relay -> SMTP2

What can happen is that because SMTP accepts relays from smtp1 it will
put inbound mail to the proper mailboxes, but will send outbound mail
also.  You may not notice it right away, but then you will start getting
returned mail that isn't from you.

I'm not sure how to stop this, I just turned it off.  Now, I'm setting
up Authentication as we speak to see if that will work for me.

If anyone knows how to do the relay while not creating a open relay,
please advise.
