That's the very *definition* of highjacking. There's a specific header ('References', IIRC) that is used to indicate what thread a message is part of. This is for various reasons, but mostly because matching subject doesn't give you full information about the tree structure of the thread, and attempting to match quoted text can lead to madness. While some mail clients provide subject based threading, it is not the correct way to indicate a message is threaded. Subject-based threading is generally only useful to work around mail clients that do not properly add a 'References' header (or whatever header you are supposed to use, I don't remember, ATM). -- "If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability." -- Gentoo Developer Ciaran McCreesh
