retrieving "Thread-Index"

How should I retrieve the non-standard "Thread-Index" headers value.

Seems that it's not parsed by java-libpst. You may try getting it from the SMTP 
headers:

/* code begins */

private String extractHeaderValue(String header, String headers) {
    Pattern p = Pattern.compile("\\n" + header + ": ([^\\n\\r]*)");
    Matcher m = p.matcher(headers);
    if (m.find()) {
        return m.group(1);
    }
    return null;
}


PSTMessage message = ...

// Find Thread-Index in SMTP headers, may be null if not set.
String smtpHeaders = message.getTransportMessageHeaders();
String threadIndex = extractHeaderValue("Thread-Index", smtpHeaders);   

/* code ends */
