No, even if the subject is completely changed a reply to a message will

contain an In-Reply-To header with the message ID of the message being replied to. Most modern mail readers will still thread that message as

the thread being replied to.
Thats what I thought too but no, if you create a completely new subject groups.io assumes you are a lazy bugger, can't be bothered to start a new message and breaks the thread totally It seems to do a pretty good job and as far as I can tell from looking at the headers it removes any "in-reply to" and creates a clean new thread. Try tracing the conversations in Thunderbird using threaded. In my Thunderbird in a threaded view it separates them when I changed to "creating CICS help". It used to be in-consistent between creating web messages and submitting by e-mail. Web messages preserved some thread info, but it was recently made consistent.
