Incoming emails are rejected if they do not pass DMARC checks.
The existing SPF control recommending that incoming emails that fail SPF checks be blocked or marked in a manner that is visible to recipients (ISM-1152) was replaced by a new DMARC control covering incoming emails being rejected if they do not pass DMARC checks (ISM-1799).
