#d# The accept option opens access to your SMTP (port 25) mail server. Use
#d# the ignore and/or deny options to block specific hosts/networks in a
#d# wider accept range. The deny option logs all rejected packets, while
#d# the ignore option doesn't log anything.
#d#
#d# Example:
#d#   accept-eth1-smtp-clients = any/0
#d#     deny-eth1-smtp-clients = 207.253.78.0/24
#d#
#d# This will let anyone connect to your mail server, except hosts in the 
#d# 207.253.78.* network.
