This one is ... interesting, in a pedantic sort of way.
And finally, there's the question of whether this is a correction or an update.
I think 1*3DIGIT clearly qualifies as a correction given that's what is in other
RFCs, but the more restrictive you get the closer you are to this being
an update.
The current ABNF has two values separated by a slash, which doesn't match
the text at all. I'm inclined to go with 1*3DIGIT because I agree that
implementations will use some version of atoi() and leading zeros don't
matter.
Has anyone ever implemented this? The text says to ignore ra= in include=
records but says nothing about redirect= records. Is that deliberate?
What happens in the common case that the redirect target is not a
hostname?
Original Text
-------------
spf-rp-tag = "rp=" 1*12DIGIT "/" 1*12DIGIT
Corrected Text
--------------
spf-rp-tag = "rp=" "100" / 1*2DIGIT
Notes
-----
As explained in paragraph 3, the value of the "rp" modifier should be an
integer value between 0 and 100. However, the specified abnf does not fit this
requirement.
