HardenedBSD/etc/mail/Makefile

#
# $FreeBSD$
#
# This Makefile provides an easy way to generate the configuration
# file and database maps for the sendmail(8) daemon.
#
# The user-driven targets are:
#
# all     - Build cf, maps and aliases
# cf      - Build the .cf file from .mc file
# maps    - Build the feature maps
# aliases - Build the sendmail aliases
# install - Install the .cf file as /etc/mail/sendmail.cf
# start   - Start the sendmail daemon with the flags defined in
#           /etc/defaults/rc.conf or /etc/rc.conf
# stop    - Stop the sendmail daemon
# restart - Restart the sendmail daemon
#
# Calling `make' will generate the updated versions when either the
# aliases or one of the map files were changed.
#
# A `make install` is only necessary after modifying the .mc file. In
# this case one would normally also call `make restart' to allow the
# running sendmail to pick up the changes as well.
#
# ------------------------------------------------------------------------
#
# This makefile uses `<HOSTNAME>.mc' as the default .mc file.  This can
# be changed by defining SENDMAIL_MC in /etc/make.conf, e.g.:
#
#		   SENDMAIL_MC=/etc/mail/myconfig.mc
#
# If '<HOSTNAME>.mc' does not exist, it is created using 'freebsd.mc'
# as a template.
# ------------------------------------------------------------------------
#
# The Makefile knows about the following maps:
# access, bitdomain, domaintable, genericstable, mailertable, userdb,
# uucpdomain, virtusertable
