I’ve got spf set up, but dmarc still fails.
This seems related to: Why is DMARC failing when SPF and DKIM are passing?

I am trying to identify, why some of my e-mails are being marked as spam by recipients, and have therefore set up SPF and DKIM. In order to check that they can be verified, I set up aggregated DMARC reports.
