        I can probably point you in the right direction (it's a
        hobby of mine), but the first step is unquestionably
        to upgrade to a modern sendmail.

        That won't be enough.  Now that one spammer knows your
        site allows relaying, you can expect more to do the same
        thing.

        The best resource is http://spam.abuse.net/ -- the patches
        and recipes at http://www.sendmail.org/ don't work for
        everybody yet.  Feel free to bug me privately if you've
        got any questions about which one to use, etc.
