To add to jeroenhd's comment, if you're only sending mail from a single server (e.g., you are using a custom domain with Proton Mail, Zoho, etc.), then you probably don't need DMARC reports at all.
To avoid them, you can remove the `rua` or `ruf` tags from your DMARC DNS record.
Dmarc Aggregate Report Domain: {mydomain.com} Submitter: {Amazon SES} Date: {2025-11-16}
