Ao usar um subdomínio com DMARC configurado para enviar RUA, é necessário adicionar registro TXT de relatórios DMARC?

  • 772

Se eu enviar um e-mail de [email protected]com [email protected]o registro DMARC de subdomain.example.com, é necessário criar um registro TXT de relatórios DMARC (por exemplo, subdomain.example.com._report._dmarc.example.com TXT "v=DMARC1")?

    Não, não de acordo com o RFC :

    When a Mail Receiver discovers a DMARC policy in the DNS, and the
   Organizational Domain at which that record was discovered is not
   identical to the [Organizational Domain][2] of the host part of the
   authority component of a [URI] specified in the "rua" or "ruf" tag,
   the following verification steps are to be taken:

 1.  Extract the host portion of the authority component of the URI.
       Call this the "destination host", as it refers to a Report
       Receiver.

 2.  Prepend the string "_report._dmarc".
