Could you send me your original dataset ?
Actually the 'smtp-policy.dat' file should be
enough for me to determine what was the input.
Also tell me example addresses, which relayed thru,
your MTA's primary domain name, and its IP addresses.
I have also considered altering the policy dataset internal
format a bit so that 'bar.foo' in localnames is not at
all related to 'bar.foo' in smtp-policy.relay, or any other
file. It will definitely need rethinking of the analysis
