The Authenticated Received Chain (ARC) protocol allows Internet Mail Handlers to attach assertions of message authentication state to individual messages. As messages traverse ARC-enabled Internet Mail Handlers, additional ARC assertions can be attached to messages to form ordered sets of ARC assertions that represent authentication state along each step of message handling paths.
