    // 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.
    var mailman = new chilkat.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.SocksHostname = "www.mysocksproxyserver.com";
    mailman.SocksPort = 1080;
    mailman.SocksUsername = "myProxyLogin";
    mailman.SocksPassword = "myProxyPassword";
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    mailman.SocksVersion = 5;
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Set the SMTP server.
    mailman.SmtpHost = "smtp.chilkatsoft.com";

    // Set the SMTP login/password (if required)
    mailman.SmtpUsername = "myUsername";
    mailman.SmtpPassword = "myPassword";

    // Create a new email object
    var email = new chilkat.Email();

    email.Subject = "This is a test";
    email.Body = "This is a test";
    email.From = "Chilkat Support <support@chilkatsoft.com>";
    success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com");

    // 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.  
    success = mailman.SendEmail(email);
    if (success !== true) {
        console.log(mailman.LastErrorText);
        return;
    }

    // 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();
    if (success !== true) {
        console.log("Connection to SMTP server not closed cleanly.");
    }

    console.log("Mail Sent!");
