The model that a receiving site is not allowed to report DMARC traffic unless that site is also generating DMARC authentication is Procrustean.  And as I noted, is likely counter-productive.

There is no such thing as "DMARC authentication".

Actually, there is.  DMARC's requirement for alignment with the author's From: field domain name asserts a specific bit of authenticated semantics that does not exist elsewhere.


The paragraph quoted is poorly written and should be rewritten to say that the report should pass either SPF or DKIM authentication as I wrote in issue #98.

It might be written better, but its requirement is for support of applying DMARC to generated reports.  That's more than just requiring SPF or DKIM.

This is separate from not asserting the requirement at all, of course.
