What's it got to do with Debian? Correct email threading is a property of the email clients the senders and receivers of emails use. You'd hope writers of those email clients would have read RFC2822 (or RFC822 if they're from last century) and implemented support for Message-ID, References, and In-Reply-To fields. -- Tixy
