    sendmail doesn't actually use an "IP number" - it uses the interface
    defined by your routing table.

    You can delete the route with the route command. Since the last two
    were duplicated, it doesn't matter which one you delete, just kill that
    one that's pointing inside.

    man route

    You can verify that it's working right be doing a traceroute to anything
    outside your network.
