    CkMailManW 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

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

    // Set the SMTP server.

    // the connection is closed.  In these cases, it is necessary to
    // call CloseSmtpConnection for the mail to be  sent.  
    // Most SMTP servers send the email immediately, and it is 
    // not required to close the connection.  We'll close it here
    // for the example:
    success = mailman.CloseSmtpConnection();
