	This works nicely:

#
#	SENDMAIL CONFIGURATION FILE FOR NFS CLIENTS.
#
#	You should install this file as /etc/sendmail.cf
#	if want mail to appear to come from one central server
#	and not to be delivered localy.  For ease of use, you
#	should then NFS mount the servers /usr/spool/mail on
#	the local /usr/spool/mail.
#
#	All this cf does is change any reference to the local
#	hostname to the name of the server, and then send the
# 	mail to the server.  All other address parsing is handed 
#	off to the server.
#
#	I believe that this configuration functions correctly, however:
#	THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY EXPRESS OR
#	IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
#	WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

#	Server cf.

# This is the name of the major relay so we can change our name.
