Re: DMARC and yahoo

    Yahoo does not seem to require DMARK.
      Simply use one of the other two options. I use SPF for my domains,
      and it makes it through their systems just fine.

      
      It looks to me that some want to be able to send list email to
      many from a bogus email address (some-domain.invalid). Simply stop
      doing that. One of the responsibilities of being a list maintainer
      is cleaning up all of bounced mess from no longer valid email
      addresses. I have advocated in the past for a email header that
      allows a bounced message to be automatically routed for the
      correct reason back to the list maintainer for processing by
      automated processes. Maybe it is time to revisit that proposal.

      
      I used to get thousands of spams from forged email. I get almost
      none now. If I got thousands, Yahoo must get millions. I applaud
      them for their courage to take a stand.

      Yahoo recognizes that  "Yahoo is the first major email
          provider in the world to adopt this aggressive level of DMARC policy on
          behalf of theirs users."

      to protect users we do not need to be aggressive .
