Further, a new end-to-end protocol to perform this function is not practical. Because Internet email (Klensin, J., Ed., “Simple Mail Transfer Protocol,” October 2008.) uses a store-and-forward mechanism to transfer email messages, it might not be possible for the sender to contact the receiving server directly. Indeed, it's often the case.
