Beat me by a minute...
I think they key misunderstanding here is the difference between being
an "open relay", which means that anyone can use your mail server to
deliver mail to anywhere and which Courier doesn't do by default, and
allowing unauthenticated relaying for your domains, which is vital
because otherwise no one could deliver mail to you.
Again, for this problem, think filtering not authentication.

Ok that's good. But the problem that I'm seeing is someone
externally can connect to this box and spam to our local domain.
That would be normal, SMTP auth prevents open relays, it can't do
anything to prevent spam. If you require all servers to authorize
then how in the world is legitmate, non-local mail supposed to get
through?
But to spam through this box you need to auth.
Which unless you've screwed up elsewhere the spammers should not
have the ability to auth, thus you're not an open relay.
Is it possible I am just missing a setting to say sendine internaly
or externally needs to auth?
I think you're missing the point of SMTP auth...
