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

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to making any calls that communicate with
    // a POP3 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 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.
    var bundle: CkoEmailBundle? = mailman.CopyMail()
