<div dir="ltr">It should only be an issue for @<a href="http://yahoo.com" target="_blank">yahoo.com</a> addresses (not @<a href="http://ymail.com" target="_blank">ymail.com</a>), when received by a mail service that also honors DMARC (notably, gmail. probably aol and yahoo itself, too). Mailman doesn't seem to strip out the yahoo DKIM headers; does anybody want to try sending to the list with an @<a href="http://yahoo.com" target="_blank">yahoo.com</a> address? My guess is that gmail users won't see it.<div>
<br></div><div>It is interesting to note that they have only enabled DMARC "reject" on the primary <a href="http://yahoo.com" target="_blank">yahoo.com</a>, not <a href="http://ymail.com" target="_blank">ymail.com</a>:<div>

</div><div><br></div><div>the "p=" is the important part: "reject" any messages that don't pass DKIM and SPF, vs "none", which is effectively test mode; the only action taken is that a daily delivery log is sent to the address in the record.</div>
