Would you mind not replying to messages and then
changing the subject
the line, thinking you are starting a new thread? On many newsreaders
your new message appears as a reply to the old thread which can be
confusing.
Or, if you know how, delete the In-Reply-To header. This is the line
which makes that threading magic work.
