if a machine has host.foo.com  .. it will only accept/relay emails
for that that hostname

if a machine has foo.com listed, it will accept ALL emails for that domain
unless a higher MX record ( lower mx number ) machine says its alive and
it will do the work

local-host-names should have localhost, localhost.domainname and
and optionally it's machine.foo.com name  so it can deal with its own
emails from cron
	"cp /dev/null /var/spool/mail/root" once in a while

for experiment ...
	- i'd use sendmail-8.13.1  and replace submit.cf too as its
	broken in whacky ways
	( 8.13.1 usually fixed any of my mail delivery/receipt issues )
