	IIRC, it's in the README file in the cf directory if you're using 
	sendmail 8.9.x.
	It's probably easiest to start from there, writing an m4 config
	file, and then 'make' it into the usual format.

	You would probably want:

	FEATURE(`relay_local_from')
	and
	FEATURE(`relay_based_on_MX')

	Sendmail 8.9.x is also 'auditted', and is a heck of a lot more
	security conscious.

	The files in /etc/mail do the followng:

	ip_allow	Allow relaying from machines with these IPs
	name_allow	Allow relaying from machines with these names
	relay_allow	Allow relaying to these hosts.

	It's probably best to start from the M4 config, and not get too
	deep into the .cf file unless you need to fine tune stuff.
