Why the mail error for domains I don't host?

    sendmail[93922]: j1L2kZa5093920: SYSERR(root): mx1.distinguish.com.
    config error: mail loops back to me (MX problem?)

    I know everyone has seen this message at least once in their life from
    improperly configured sendmail. However, my log is filling up with
    these messages for domains I do not host.... and when I dig the
    mentioned host, it always resolves to localhost (127.0.0.1). This
    happens over and over again on for domain after domain. Are there
    really that many unskilled admins who publish their mail server's
    address as localhost, or is this some sort of hack that I should worry
    about?
