Actually, Unico is not the only one. What I've found is that Mozilla 
uses the In-Reply-To header whereas Outlook (at least some version) uses 
"Thread-Topic" and "Thread-Index".

Outlook's headers seem strange to me, as I don't know how a mailer can 
rebuild a thread tree with just an indentifier for the thread, but no 
information about the posts relationships.
