I thought Google is one the organizations pusing adaptations of DMARC.
But I’ve been wondering why gmail.com’s DMARC policy is “none”.
Here is gmail.com’s dmarc record.
v=DMARC1; p=none; sp=quarantine; rua=mailto:mailauth-reports@google.com
They enable quarantime for subdomain, but none for parent domain.
Does anyone know why?
