This is a simple trend chart of how well your DMARC implementation is performing.
DMARC compliant mail is mail that both authenticates and aligns. This means that for SPF, the reverse DNS of the sending IP matches the domain of the visible from address, and for DKIM, that the signature is from the same domain as the visible from address. To be fully DMARC-compliant, all mail that authenticates should align to the sending domain.
