Google DMARC reports are back! After going quiet since April 13, Google has resumed sending DMARC aggregate reports as of 19:15 UTC today. So far, the reports only include data from yesterday (April 16), but it is a good sign that things are starting to flow again.
I purged over a million DMARC reports from GoDaddy from our database because they incorrectly indicated SPF passed without identifier alignment. These erroneous reports were misleading our clients. I reported this issue some time ago, but it has yet to be addressed. We will continue to disregard these incorrect reports until the issue is resolved.
If you're using a DMARC monitoring solution other than URIports.com and notice unknown IP addresses passing SPF validation in GoDaddy DMARC reports, please understand that this is due to a known bug and is not cause for concern.
