For completeness, a different route to take would be to publish a DMARC record at "_dmarc.888.com". You'd then receive data on all sub-domains of <a href="http://888.com">888.com</a>, including <a href="http://email.888.com">email.888.com</a>.</div></div><br><blockquote type="cite"><span class="Apple-style-span" style="font-family: Calibri, sans-serif; font-size: 15px; ">I couldn’t find any place where this is explained in a simple manner on <a href="http://dmarc.org/" style="color: blue; text-decoration: underline; ">dmarc.org</a>.</span></blockquote><div><br></div></div>Nor could I. I'm afraid I had to dip into the spec to find the description. It should probably be mentioned on the Overview page, in the "Anatomy of a DMARC resource record in the DNS" section..<div><br></div><div>=- Tim</div><div><br><div><br></div></div></body></html>
