Hi,

Our company has Exchange server and we want to implement DMARC as a receiver. As below link says receiver like mailbox provider should implement DMARC themselves, we use our company server as mail server so we don't even know whether DMARC is implemented as a receiver. Please let me know how can I implement DMARC in our Exchange server.

Microsoft recently added DMARC support for Exchange Online Protection, but it does not exist in Exchange 2013 on-premises.
