I just enabled this here. I tested and it looks like it works (threads not broken) on - Thunderbird - kmail - Claws but are broken on Evolution. PS. In the message-id, claws uses the hostname, while TB and kmail use the sender domain. Note that the test used a test folder which only contains the test messages. I have no idea if threads will still be correctly detected with a folder full of mail. I would conjecture that it "works" because the response comes from a user listed in the recipients of the original mail. so threads would break if a message is sent to a group alias (or a list) or if the recipient responds with a different address. I might test this...
