There's the problem then. Try and figure out whats not configured properly. You can also test the domain at https://dmarcian.com/ Check you emails from Apple and see make sure your DNS settings match what Apple sent you and also set a DMARC policy, even something basic like v=DMARC1; p=none would do for the time being.

I have published a DMARC record a week ago using the generator at https://dmarcian.com/... I have published SPF and DKIM, which both show as being valid for my domain, but DMARC doesn't show up. I have tried configuring it different ways, adding and deleting, and nothing will get these checkers to show that it's valid. Source: over 1 year ago

Excellent response. I'd also add using https://dmarcian.com to help check along with mxtoolbox.com. Source: over 1 year ago

This is a screenshot from Instantly. Tried using the checker on dmarcian.com as well and it gave me the same error. Source: over 1 year ago

It's been a few days since I've configured the SPF/DKIM on my domain but the DMARC I put in isn't working. I snagged a record from dmarcian.com. Source: over 1 year ago

The url I want is https://mxtoolbox.com/ and the https://mxtoolbox.org/ one redirects to malware. Source: 6 months ago
