    // See Global Unlock Sample for sample code.

    // The mailman object is used for receiving (POP3) 
    // and sending (SMTP) email.
    CkMailMan mailman;

    // To connect through an HTTP proxy, set the HttpProxyHostname
    // and HttpProxyPort properties to the hostname (or IP address)
    // and port of the HTTP proxy.  Typical port numbers used by
    // HTTP proxy servers are 3128 and 8080.
    mailman.put_HttpProxyHostname("www.my-http-proxy.com");
    mailman.put_HttpProxyPort(3128);

    // Important:  Your HTTP proxy server must allow non-HTTP
    // traffic to pass.  Otherwise this does not work.

    // Set the POP3 server's hostname
    mailman.put_MailHost("pop.someMailServer.com");

    // Set the POP3 login/password.
    mailman.put_PopUsername("myLogin");
    mailman.put_PopPassword("myPassword");

    // Copy the all email from the user's POP3 mailbox 
    // into a bundle object.  The email remains on the server.
    // 
    // NOTE: All methods that communicate with a POP3 server
    // will automatically connect and authenticate (i.e. login)
    // if not already connected.  The connection will remain
    // open after the method call returns so that subsequent
    // calls do not need to re-establish the connection.
    // In this case, the connection is established via the HTTP
    // proxy.
    CkEmailBundle *bundle = mailman.CopyMail();
    if (mailman.get_LastMethodSuccess() == false) {
        std::cout << mailman.lastErrorText() << "\r\n";
