Yahoo DMARC policy

Yahoo recently updated the DMARC (Domain-based Message Authentication, Reporting and Conformance) record with "p=reject" for Yahoo domains. This was done to protect our users from increasing email spam that uses Yahoo email addresses from other mail servers.

All DMARC compliant mail receivers (including Yahoo, Hotmail, and Gmail) are now bouncing emails sent as Yahoo email addresses that aren't sent through Yahoo servers.
