Policies: https://dmarc.org/2022/03/dmarc-policies-up-84-for-2021/
For mailboxes that implement DMARC and send reports, Valimail (and Dmarcian
I believe) have historically tracked and published that. I'll hunt down
that data tomorrow. Off the top of my head, it was about 80% of mailboxes
globally
Are there any public numbers on the amount of mail that is subject to
DMARC policy, number of mailboxes implementing DMARC policies, number
sending reports, stuff like that?
Someone was also asking about PSD adoption but I assume at this point
it is still zero other than some small tests.
R's,
