    It is common for elements within a typical email handling topology
    to be unaware of whether individual local-parts are valid for the
    mail it accepts. For example, so-called "edge" servers which provide
    security oriented services for downstream mail handling elements
    often do not have an exhaustive listing of all valid local-parts for
    a given domain. Thus, they are sometimes forced to accept and process
    messages which might otherwise be rejected as "user unknown".
    Similarly, entities offering "backup MX" mail services are rarely
    privy to a complete local-part listing and are therefore often decide
    to accept messages which might otherwise be rejected. Finally, even
    within a common administrative framework of several locally maintained
    and controlled SMTP servers in a load balanced configuration, it is
    not always possible for all servers to access a common local-part
