If you want to ever (and you want to) do a check like the one above,
you must use it for scoring only.
[And optionally] if you want this scoring to be effective, you can
apply delays if the total score is below the reject threshold. You
can also while list (that is add a !hosts = +whitelisted_hosts) those
hosts you know are forwarding regularly to youyou don't want to delay
them unnecessarily.
