### END INIT INFO

# OpenDKIM startup script v1.4 for RHEL/CentOS/Fedora
# by Steve Jenkins (SteveJenkins.com) - 07-07-2011
# Based on a script by Andrew Colin Kissa (TopDog) for dkim-milter - 28-05-2009
# - Additional functionality to prevent multiple instances and a reload
#   handler by Chris LaJoie - 11-01-2011
# - Added notification (along with with current PID) if "start" is issued when
#   OpenDKIM is already running - 02-15-2011
# - Modified chkconfig: line so that a simple "chkconfig --add opendkim" is
#   all that is required to automate startup - 07-07-2011
