SPF and DKIM were great, but each had flaws. SPF struggled with address alignment and handling forwarded emails, while DKIM's complexity made it challenging to manage failures. Enter DMARC: it combines SPF and DKIM, aligns headers for accuracy, and gives clear guidance on dealing with authentication issues, bridging the gaps left by its predecessors.

DMARC History: Why SPF and DKIM Weren’t Sufficing

The RFC (Request for Comments) is contemplating this change, impacting email authentication protocols. Keep up-to-date with this evolving standard to understand its implications on email security and authentication measures.
