</span>> header.from=<a href="http://skimium.emv5.com" rel="noreferrer" target="_blank">skimium.emv5.com</a>' so you don't know that openDMARC *actually*<br>

</span>Ok, but still I think Google is wrong here and OpenDMARC is right - at least,<br>
if my interpretation of the RFC is right. There is nothing written, that the<br>
actually tested domain should be reported in the header.from field.<br>
<br>
What OpenDMARC actually tested should be recorded in the history file, which<br>
will be imported into the database.</blockquote><div><br></div><div class="gmail_default" style="font-size:small">I defer to your greater knowledge here. I don't use the history file. My main concern was that openDMARC was testing the right thing, which you have confirmed it is.

Maybe an <u>additional</u> field could be added to the AR header only in cases where the appropriate valid DMARC record used was found for a domain different to the 'from' header domain - in this case, for example: tested_domain=<a href="http://emv5.com">emv5.com</a>.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Dominic</div></div></div></div>
