Demonstrates how to communicate with an SMTP server via a SOCKS4 or SOCKS5 proxy. Unicode C++

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // The mailman object is used for sending and receiving email.
    CkMailManW mailman;

    // 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.put_SocksHostname(L"www.mysocksproxyserver.com");
    mailman.put_SocksPort(1080);

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

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

    // Set the SMTP login/password (if required)
    mailman.put_SmtpUsername(L"myUsername");

    // Call SendEmail to connect to the SMTP server and send.
    // The connection (i.e. session) to the SMTP server remains
    // open so that subsequent SendEmail calls may use the
    // same connection.

    // 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:
    success = mailman.CloseSmtpConnection();
