    let mailman = CkoMailMan()!

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

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

    // Get the number of messages in the mailbox.
    var numMessages: Int = mailman.getMailboxCount().intValue

    // Message numbers are specific to a POP3 session. 
    // If a maildrop (i.e. inbox)  contains 10 messages, 
    // the message numbers will be 1, 2, 3, ... 10. 
    // If message number 1 is deleted and a new POP3 session 
    // is established, there will be 9 messages numbered 1, 2, 3, ... 9. 

    var i: Int = 1

    var email: CkoEmail?
    while i <= numMessages {

        email = mailman.fetch(byMsgnum: i)
        if mailman.lastMethodSuccess != true {
            print("\(mailman.lastErrorText!)")
