        // To use a SOCKS4 or SOCKS5 proxy, simply set the following
        // properties prior to making any calls that communicate with
        // an SMTP server:
        // The SOCKS hostname may be a domain name or
        // IP address:
        mailman.setSocksHostname("www.mysocksproxyserver.com");
        mailman.setSocksPort(1080);
        mailman.setSocksUsername("myProxyLogin");

        // Set the SOCKS version to 4 or 5 based on the version
        // of the SOCKS proxy server:
        mailman.setSocksVersion(5);
        // Note: SOCKS4 servers only support usernames without passwords.
        // SOCKS5 servers support full login/password authentication.

        // Set the SMTP server.
        mailman.setSmtpHost("smtp.chilkatsoft.com");

        // Set the SMTP login/password (if required)

        // Some SMTP servers do not actually send the email until
        // 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:
        try {
            mailman.closeSmtpConnection();
