Fetch Oldest/Newest IMAP Email

Emails may be downloaded by sequence number. Assuming the selected mailbox is not empty, the oldest email is at sequence number 1, and the newest email is at sequence number N. The FetchSingle method may be used to download by sequence number. Swift

    var success: Bool = false

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