Re: [spfbis] Authentication-Result (Issue 10?)

[S Moonesamy <[e-mail]>]

Hello,

This is a very rough summary of the Authentication-Results and 
Received-SPF: headers discussion.

Hector Santos mentioned presenting this as a migration, not just as 
an exclusive replacement [1].  John Levine suggested having more 
(Authentication-Results:) details about SPF results in a separate 
draft [2].  One of the arguments mentioned by Douglas Otis  is that 
it would never be in a users interest to adopt result formats aimed 
at disabling third-party competitors by omitting essential 
information [3].  Murray Kucherawy commented that it should be 
sufficient to point out the two available options for post-MTA 
communication, explain why we're documenting two of them, and leave 
it there [4].

As an individual comment, this working group had to determine a 
resolution to two experiment.  That happened because consensus did 
not clearly support one over the other.  The working group will be 
conducting a similar experiment if it is WG consensus to support both options.

Regards,
S. Moonesamy
