## TNOS etc/mailrelay file.
##
## The order of this file is important. Specific hosts first, then
## networks / domains in decreasing match order
##
## First define calling hosts that we relay mail for, and those
## that we specifically wish to lock out of mail relay with ! prefix
## Use dotted quad addresses with '/bits' netmask.
##
# Deny relay to the host 44.131.177.254
!44.131.177.254
#
# Permit all amprnet hosts with a 44 address to relay mail through us.
44.0.0.0/8
#
# Uncommenting this line below will block all other hosts from relaying.
# !0.0.0.0/0
#
## ---------------------------------------------------------------------
#
## If a host is not blocked or specifically enabled above, the criteria
## of whether or not we relay is decided by which domain name the mail
## is either originally from or to.  Use proper domain names with
## wildcards. We don't need to include our own hostname, but you *MUST*
## take account of any MX records pointing to your box.  The ! directive
## does not work here - this part of the file is only permit - anything
## not mentioned is deny.
##
# uncomment if foo.bar.isp.com is an MX record pointing to this box:
#foo.bar.isp.com
#
# allow any mail to or from @ ampr.org addresses
*.ampr.org
#
# Uncommenting the line below would allow relay from or to anyone
#*
#
## End of file
