Domain-based Messaging Authentication Reporting and Conformance(DMARC) is highly recommended and fully supported by MailChannels.
DMARC Sender Domain policies:
p=reject
Unauthorized email doesn’t get delivered. Reject these messages entirely.
p=quarantine
Unauthorized email should be delivered to a special/spam folder or suspended in a quarantine queue.
p=none
Monitors your email traffic. No further action is taken.
The following table demonstrates how policy is handled depending up on the type of Spam Handler chosen for your protected inbound domain.
