DMARC is unable to authenticate this email: no 3rd party support. > Another way would be: your use case is obscure > and you shed no light on it. actually, this is a pretty common practice, especially for personal or small business domains. out of my 15 business customers, 13 use exactly this. and i mainly support small business, so my experience is pretty in line with this world, unlike, i imagine, ppl working for ymail, google, paypal, fb or whoever sat and designed DMARC. > Please, explain with more detail how is your usage > scenario excluded by DMARC.
