Here are the results as of right now:
Give the expected results: 82 tests
Give the wrong result: 48 tests
Give a correct but not preferred result (mostly because of SPF records and IPv6): 6 tests
Fail (crash): 9 tests
So, depending on how you look at it, RASPF passes between 61% and 56% of the tests.
Not bad so far :-)
Update: As of 20:52 ART, it's 105/0/35/5 and 72-76%. The bad news is that that was all the low hanging fruit, and now it gets much harder.
