    // The mailman object is used for receiving (POP3) 
    // and sending (SMTP) email.
    let mailman = CkoMailMan()!

    // 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
    // HTTP proxy servers are 3128 and 8080.
    mailman.httpProxyHostname = "www.my-http-proxy.com"
    mailman.httpProxyPort = 3128

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

    // Set the POP3 server's hostname
    mailman.mailHost = "pop.someMailServer.com"

    // Set the POP3 login/password.
    mailman.popUsername = "myLogin"
    mailman.popPassword = "myPassword"

    // Copy the all email from the user's POP3 mailbox 
    // into a bundle object.  The email remains on the server.
    // 
    // NOTE: All methods that communicate with a POP3 server
    // will automatically connect and authenticate (i.e. login)
    // if not already connected.  The connection will remain
    // open after the method call returns so that subsequent
    // calls do not need to re-establish the connection.
    // In this case, the connection is established via the HTTP
    // proxy.
    var bundle: CkoEmailBundle? = mailman.copyMail()
    if mailman.lastMethodSuccess == false {
        print("\(mailman.lastErrorText!)")
        return
    }

    var i: Int = 0
    var email: CkoEmail?
    while i < bundle!.messageCount.intValue {
        email = bundle!.getEmail(i)
        print("From: \(email!.from!)")
        print("Subject: \(email!.subject!)")
        email = nil
        i = i + 1
    }

    bundle = nil

    var success: Bool = mailman.pop3EndSession()
