    // The mailman object is used for sending and receiving email.
    let mailman = CkoMailMan()!

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

    // Set the SMTP login/password (if required)
    mailman.smtpUsername = "myLogin"
    mailman.smtpPassword = "myPassword"

    // Create a new email object
    let email = CkoEmail()!

    // Load a .eml file into the email object.
    var success: Bool = email.loadEml("/data/myEmail.eml")

    // 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.send(email)
    if success != true {
        print("\(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 {
        print("Connection to SMTP server not closed cleanly.")
    }

    print("Mail Sent!")
