I think there's a maximum line length specified in the RFC for SMTP
transactions, but like any other header, you can add a line break and
indent the next line to extend the header. So I guess there isn't a
specific limit for this header.
Also, apart from the In-Reply-To and References headers, consider
threading on "Re: original_subject" at the same time -- although all
these methods together might be complex to program. But very common
mailers (Outlook and Outlook Express) do not use special headers for
threading.
