    Many thanks to everyone who suggested using mailertable to forward the
    messages. I hadn't used that particular feature of sendmail for over 5
    years, when I had to forward some email to a uucp-only site.

    In my defense, though, the section on mailertable in the bat book
    neglects to mention that enclosing the RHS host name in square brackets
    turns off MX record lookups for that host. I only discovered that in the
    cf/README file.

    Once again, thanks for all the help.
            - Rich
