That would be wonderful. History says that's unlikely... > What does Thunderbird do? Does it break Outlook 2010 threading, too? I don't normally used Thunderbird. Searching the web a found a few references to Thunderbird using Thread-Index fields to thread messages, but nothing about setting the field. According to a quick test, it does not appear to set Thread-Index. I did find reference to Evolution using Thread-Index and inserting References headers based on Thread-Index [1]. However, another quick test of Evolution indicates that it doesn't preserve Thread-Index. But since mutt sucks less that either of those, it can do better! -- Bob [1] http://developer.gnome.org/evolution-exchange/stable/ximian-connector-mail-threading.html
