I have investigated. A bit of skepticism goes a long way. Never be taken
in. So, for the record:
In Thunderbird if you click "Write" (not "Reply" or "Reply All"), the
headers are according to the semantics of "Write", i.e., no
"References:" or "In-Reply-To:". Insofar as headers, this is correct
When Thunderbird gets a post (from your "Write" or from outside) with no
"References:" and "In-Reply-To:" header, but with "Subject:" same as
existing posts, it still displays them together as a thread. But this is
just a display trick - "References:" and "In-Reply-To:" are not fudged.
Evidently, this is a measure against non-compliant posts. Furthermore,
this is configurable. In the config editor, look for
The presence of the setting implies that the programmers know what they
are getting into. There is a tension between following the rules and
inter-operating with those who don't follow the rules. This is not a
bug; this is a conscious compromise. And you can change it.
Changing the setting doesn't change the threading structure of existing
posts - the decisions made back then were recorded. (There is also a way
to delete that, along with lots of other meta-data: delete the
appropriate .msf file.) The setting is effective for posts seen henceforth.
I can't blame you for being not observant. Afterall, this is precisely
what I'm alluding to with "everyone can haz PC", or rather, the way Bill
Gates executes it. Everyone becomes superficial, everyone just looks at
what's displayed on the screen - or rather, fictionized on the screen -
and jumps to conclusions.
Never be taken in.
