// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    CkEmail email = new CkEmail();

    // First, load an email from a file. 
    // Note: an email object may be loaded from a file, or
    // downloaded directly from a POP3 or IMAP server...

    success = email.LoadEml("testReceivedHdrs.eml");
