bounce message
     
        A notification message returned to the sender by a site unable
        to relay {e-mail} to the intended recipient or the next link
        in a {bang path}.  Reasons might include a nonexistent or
        misspelled user name or a {down} relay site.  Bounce messages
        can themselves fail, with occasionally ugly results; see
        {sorcerer's apprentice mode} and {software laser}.  The terms
        "bounce mail" and "barfmail" are also common.
