[Evolution] Threaded View in evolution

[Sebastian Gödecke <simpsonetti googlemail com>]

Hi, i want to use mails in my folders as threaded view, but not sorted
by subject rather than sorted by references or message-id or something
else.
Now my mails were sorted all by subject and this is sometimes wrong.
How could i do this?
