#	SENDMAIL CONFIGURATION FILE
#
#	supports internet style addressing
#	over UUCP and ethernet links.
#
#	This configuration file is based on the smail configuration
#	file from the UUCP project.  It's intended purpose is to be
#	a default, simple minded configuration file for those sites
#	that have not yet set up smail, and it's cohorts.

# This configuration file uses the uname default, unless otherwise modified.
# $D and $=D list all domains in which this host sits.
# $D goes into outbound addresses, i.e. "user@$w.$D".
# it will will be turned into $D.
# HOSTNAME needs to be modified for each site (if there is no ethernet).
