What is ARC?
Maintaining SPF and DKIM results even after forwarding! We introduce situations where ARC is helpful in our blog.
ARC (Authenticated Received Chain) is one of the email authentication systems that displays the authentication evaluations at each stage when processing emails. In simpler terms, Authenticated Received Chain can be described as a series of verifications of email messages that allows each entity handling the email message to efficiently verify all previously processed entities. ARC, a relatively new protocol published and documented as "Experimental" in RFC8617 in July 2019, enables email verification by the receiving server even when SPF and DKIM have been invalidated by intermediary servers. 【Contents】 ■ What is ARC (Authenticated Received Chain)? ■ DMARC's ARC ■ How does Authenticated Received Chain help? ■ How does DMARC's ARC work? *You can view the detailed content of the blog through the related links.
