Reading a DMARC record

A DMARC record notifies email recipients if a domain has been configured for DMARC and includes the domain owner’s policy. A DMARC record is enclosed in the tag and encloses subtags that provide information, such as:

  • The tag encloses the name of your domain
  • The tag contains information about relaxed (r) or strict (s) DKIM alignment
  • The tag contains information about relaxed (r) or strict (s) SPF alignment.
  • The tag indicates the requested policy (none, quarantine, or reject) when an email fails DMARC authentication
  • The tag is for subdomain policy used to indicate a separate DMARC record for the subdomain.
  • The tag is used to specify the percentage of emails to be checked for authentication in an email stream but is optional.
