Hi Bryan,

Respectfully, your MUA is not the only MUA. Others work differently.

GMail, for example, follows the message IDs as you say but assumes
that if you change the subject line in your reply (more than adding
"Re:") then you intend to start a new thread from that point in the
discussion. It groups messages accordingly.

This is not an unreasonable expectation: if you merely want to
continue the current conversation without going off on a new tangent
then there's no need for a different subject line.

Regards,
Bill Herrin
