Ahh, I think that explains it. There is this email header that we normally
don't see called "message-id" which many mail clients use to collapse
duplicate messages, and an "in-reply-to" field which references that ID so
mail clients can organize reply threads.

So unfortunately the same subject isn't enough for some mail clients (at
least not mine (gmail)) to preserve the same message thread.

Is this an issue for anyone else's client?

Perhaps I should switch, or there is a setting to make gmail more
permissive in its thread organization. Does anyone know?
