ARC (Authenticated Received Chain) is an email authentication mechanism, sort of. The point of ARC is to encapsulate a check of email authentication results and include it in forwarded mail.If I receive email at an address, then I forward mail to another address, authentication results are difficult for the mail server at the second receiving site to interpret correctly. SPF works on a “last hop” methodology, meaning that a server doing an SPF check can only check the server that just connected to it — making it incompatible with email forwarding, because email forwarding involves more servers and thus more “hops.” A DKIM authentication signature is supposed to be compatible with email forwarding, but there are enough glitches out in the wild — encoding problems, rewriting headers for forwarding (or adding headers or footer text for mailing lists) that it just doesn’t work perfectly 100% of the time. And then
“Technologies recommended in support of core Simple Mail Transfer Protocol (SMTP) and the Domain Name System (DNS) include mechanisms for authenticating a sending domain: Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM) and Domain based Message Authentication, Reporting and Conformance (DMARC).” The post National Institute of Standards and Technology (NIST) Provides DMARC Guidance appeared first on dmarcian.
