        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822

// The email could alternatively be loaded as a result of downloading from an IMAP or POP3 server..

    email.GetDigestEmail(i,eDigest);
    console.log(i + ":" + eDigest.FromAddress + ", " + eDigest.Subject);
    var m = eDigest.GetHeaderField("Message");
    if (eDigest.LastMethodSuccess == true) {
