# DNS Block List Host File
#
# This file lists some hosts which perform IP lookups to see if an
# IP is on their list.  The IP will be reformatted and appended to
# the host names listed here and then a DNS lookup will be done.
#
# The format of this file is pretty simple.  Each entry is composed of two
# parts - the host to check and a message to display during the SMTP session
# and in the log file if a match is discovered.  The $IP$ macro will be replaced
# by the offending IP address if a match is made.
