Many reputation systems can output much more detailed information, and many 
work on scales other than 0 to 100 (or -100 to 100.)  Even those which do use 
numeric values may not attach the same meaning to the same numbers.

* "Report-To" (or "Reportable", or "Abuse-Report-To") as an additional 
Authentication-Result method whereby the MTA responsible for receiving 
the message conveys that, based on other methods and any additional 
knowledge internal to the MTA, that host will accept an ARF for this 
message. The syntax may be something like

  Authentication-Results: resp-mta.example.com;
    report-to: abuse;

to mean <abuse(_at_)resp-mta(_dot_)example(_dot_)com>, which would be assumed 
by 
default in case resp-mta.example.com is an SMTP host (MX/A/AAAA).
Variations?

This part's definitely overloading Authentication-Results, IMHO.
