Yellow Flag<p>Did anybody figure out why <a href="https://infosec.exchange/tags/GMail" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GMail</span></a> is sending so many duplicate <a href="https://infosec.exchange/tags/DMARC" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DMARC</span></a> messages? Normally I get around three, this time it was eleven however. The mail headers show that the problem happens before transmitting the message to me: there is an <code>X-Received</code> header showing an internal address at Google receiving this message at different times, ranging from 03:10:55 to 04:58:07 PDT.</p><p>This isn’t really an issue, I’m merely curious why it happens.</p>

Is that normal, or should I still be worried, that something else is wrong? Do I receive reports when all is good?</p>
