Hello,

We're looking for reasons result in DMARC validation failures.
One assumption are random failures while fetching DKIM public keys from dns.

We have CNAMEs pointing to dkim.amazonses.com So I inspected the  
domain and notices a DNSVIS warning:
https://dnsviz.net/d/dkim.amazonses.com/Z343qg/dnssec/

As this is not a new issue, I don't think, it's the reason for our  
primary issue but shouldn't that be fixed anyway?
