I am having problems configuring a Sun with SunOS 4.1.1 as our Internet
mail host.  I have copied /usr/lib/sendmail.mx to /usr/lib/sendmail
and copied sendmail.main.cf to /etc/sendmail.cf, but I am not sure
what to set for the lines DM, DR, and CR in sendmail.cf:
the major relay mailer and major relay host.
I think the major relay mailer should be "ddn" because when I set the major
relay host to point to a mail gateway outside of our domain I am able to
send Internet mail properly.  What I want to be able to do is configure
the Sun itself as the major relay host.  If I set the major relay host
to the name of the Sun itself sendmail complains about the originating host
name: host name configuration error.
I know that our domain name server is OK because until recently our 
Internet mail host was running on another machine with no problems.

Any help would be much appreciated.
