I read this Find Gmail URLs via IMAP , but I noticed Greplin ( https://www.greplin.com ) can successfully get the thread id.
Can anyone help me here?

Gmail provides an attribute
X-GM-THRID
for stream id
you can use imap fetch function to get stream id.
see the documentation here http://code.google.com/apis/gmail/imap/
I think it can be accessed through libgmailer.php (curl) http://sourceforge.net/search/?q=libgmailer
