func chilkatTest() {
    var success: Bool = false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

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

    mailman.mailHost = "pop.example.com"

    // Set the POP3 login/password.

    mailman.popPassword = "myPassword"

    // Set the ImmediateDelete property = false
    // When the DeleteEmail method is called, the POP3 session
    // will remain open and the emails will be deleted all at once
    // when the session closes.
    mailman.immediateDelete = false

    // Download email headers.
