No, the In-Reply-To header in *my* post is the post *I* have replied to, 
i.e. that's the Message-ID of *your* earlier post.

No, the headers would be:
To: python-list at python.org
In-Reply-To: <51B7084E.9040000 at gmail.com>
References: <mailman.2964.1370862786.3114.python-list at python.org> 
<51b5bb53$0$29997$c3e8da3$5496439d at news.astraweb.com> 
<71d585e6-bb98-47b7-9a45-7cde1ba0c48f at googlegroups.com> 
<51B7084E.9040000 at gmail.com>

Basically, you should follow RFC 2822 and RFC 1036 if you don't mess up 
with message threading.

You also need to know that you can't add these headers manually in 
Thunderbird out of the box. You would need to edit the configuration.

Bye, Andreas
