@Tom: PostMark do offer the same service as Mailgun but I'm not suggesting you switch. It's more that they *also* have a service to process DMARC reports in addition to their mail sending capabilities. Kind of like Google have GMail and Maps but you can still be an Outlook.com email user and use Google Maps instead of whatever Microsoft's map offering is.
I don't see the need for Mailgun to enter the DMARC report processing space (unless they want to) as it's a completely different business to sending mailshots etc. Postmark just happen to be an outlier an that they do both.
