DMARC monitor a couple of domains for some period of time


I changed my dmarc records for a couple of domains to get response mails. descriptive text “v=DMARC1; p=quarantine;; ruf=mailto:dmarc@; pct=100”.

I got a lot of daily reports (from all of the domains, i entered), but almost only from google. But I’m sure at least a lot of mail is delivered to a lot of other different mail hosts.

(a .cz provider also gives dmarc reports).

Just curious, why only google is responding. I also expected responses from microsoft, yahoo, …

I don’t know the definitive answer, but suspect that it may be too low of volume.
