My appologies for yet a 3rd post on this topic; I promise this is the
last. There were a couple subtle bugs in the code I shipped out last
week which did not become apparent until I have been using my hacks
for a couple of days. The following code SHOULD be correct:
sendmail.main.cf:
----------------------------------------------------------------------
############################################################
#
# 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.
#
# @(#)main.mc 1.17 90/01/04 SMI
#
### 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)
# Changed from DMsmartuucp by mjk on 9-26-90
DMddn
# major relay host: use the $M mailer to send mail to other domains
# Relay mailer set to apple.som by mjk on 9-26-90
DR apple.com
CR apple.com
# 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)

#
# General configuration information
# local domain names
#
# These can now be determined from the domainname system call.
# The first component of the NIS domain name is stripped off unless
# it begins with a dot or a plus sign.
# If your NIS domain is not inside the domain name you would like to have
# appear in your mail headers, add a "Dm" line to define your domain name.
# The Dm value is what is used in outgoing mail. The Cm values are
# accepted in incoming mail. By default Cm is set from Dm, but you might
# want to have more than one Cm line to recognize more than one domain
# name on incoming mail during a transition.
# Example:
# DmCS.Podunk.EDU
# Cm cs cs.Podunk.EDU
#
# known hosts in this domain are obtained from gethostbyname() call
# Added by mjk on 9-26-90
Dmrpal.com
Cm elements elements.rpal.com rpal.com
Fm /usr/local/etc/mail-aliases
# New domain added by mjk on 1-29-91
DNrpal.rockwell.com
# Version number of configuration file
# Changed from DVSMI-4.1 by mjk on 9-26-90
DVrpal-4.1.0

# name used for error messages

# Name Canonicalization
# Internal format of names within the rewriting rules is:

# We try to get every kind of name into this format, except for local
# names, which have no host part. The reason for the "<>" stuff is
# that the relevant host name could be on the front of the name (for
# source routing), or on the back (normal form). We enclose the one that
# we want to route on in the <>'s to make it easy to find.
