What's running on the SMTP server?  I gather it isn't sendmail (lets
not get into that again please....).  But, sendmail can certainly do
what you want.

DON'T edit the .cf files directly (like one used to do in the deep
dark past).  Rather, edit the m4 file and let M4 do all the heavy
lifting.  Look at LOCAL_RELAY and MAIL_HUB in cf/README and set up
accordingly, eg:

	LOCAL_RELAY applies to unqualified names (e.g., "eric").
	MAIL_HUB applies to names qualified with the name of the
		local host (e.g., "eric at mastodon.CS.Berkeley.EDU").
	SMART_HOST applies to names qualified with other hosts or
		bracketed addresses (e.g., "eric at mastodon.CS.Berkeley.EDU"
		or "eric@[127.0.0.1]").
