#	Sendmail configuration file for "MAIN MACHINES"
#
#	You should install this file as /etc/sendmail.cf
#	if your machine is the main (or only) mail-relaying
#	machine in your domain.  Then edit the file to
#	customize it for your network configuration.
#
#	See the manual "System and Network Administration for the Sun
#	Workstation". Look at "Setting Up The Mail Routing System" in
#	the chapter on Communications.  The Sendmail reference in the
#	back of the manual is also useful.

###	local info

# my official hostname
# You have two choices here.  If you want the gateway machine to identify
# itself as the DOMAIN, use this line:
Dj$m
# If you want the gateway machine to appear to be INSIDE the domain, use:
#Dj$w.$m
# Unless you are using sendmail.mx (or have a fully-qualified hostname), use:
#Dj$w

# major relay mailer - typical choice is "ddn" if you are on the
# Defense Data Network (e.g. Arpanet or Milnet)
DMsmartuucp

# major relay host: use the $M mailer to send mail to other domains
ifdef(`m4GATEWAY',, `define(m4GATEWAY,ddn-gateway)')dnl
DR m4GATEWAY
CR m4GATEWAY

# If you want to pre-load the "mailhosts" then use a line like
# FS /usr/lib/mailhosts
# and then change all the occurences of $%y to be $=S instead.
# Otherwise, the default is to use the hosts.byname map if NIS
# is running (or else the /etc/hosts file if no NIS).

# valid top-level domains (default passes ALL unknown domains up)
