    What is ARC?

    When an email sender or Internet domain owner uses email authentication to make it easier to detect fraudsters sending messages that impersonate their domain, some services like mailing lists or account forwarding may cause legitimate messages to not pass those mechanisms, and then they might not be delivered. These services may be referred to as intermediaries because they receive a message, potentially make some changes to it, and then send it on to one or more other destinations. This kind of email traffic may be referred to as an indirect mailflow.

    ARC preserves initial email authentication results across subsequent intermediaries (“hops”) that modify the message and thus will cause email authentication to fail to verify when the message reaches its final destination.

    ARC Specification for Email
    draft-andersen-arc-00 - Authenticated Received Chain (ARC)

    This was primarily introduced to help overcome the issues of failed results of DMARC with forwarders and mailing list. DKIM breaks and the ARC solution was put in place to preserve the original results as the email gets bounced around from forwarders.

    Have you implemented? Any tips for anyone looking into ARC? Is there any Q&A that you encountered and can share?
