It would appear to me that it is that paragraph which acknowledges, explicitly, that this is not so. It says: Note that the RFC5321.HELO identity is not typically used in the context of DMARC (except when required to "fake" an otherwise null reverse-path), even though a "pure SPF" implementation according to [SPF] would check that identifier. - Roland _______________________________________________ dmarc-discuss mailing list dmarc-discuss@dmarc.org http://www.dmarc.org/mailman/listinfo/dmarc-discuss NOTE: Participating in this list means you agree to the DMARC Note Well terms (http://www.dmarc.org/note_well.html)
