Actually, I suspect it's not your mail app. Have you told MS to remove some
headers or so? Or use some header-mangling milter? 
Check mail going thru your system from other clients (=programs).
Send thru another system. Compare the results.
I think your mail system is seriously broken, see below.

it's not ok. This last message-id simply does not exist at all!
And if it existed this would mean you reply to yourself!
*All* the message-ids you reference in the last postion or in In-Reply-To do not
exist! And that's the problem! And as they end with out-b.mx.mail-launder.com it's
rather your mail system doing this as I don't see how your local mail app should
be adding that unless you are writing the messages on that machine. I suspect that
all mail going thru it is broken in this way.

Moreover, your own messages are getting sent without a message-id, so that the 
mailing-list server has to add it. Which is very unusual and likely to be 
considered some spam score points worth on many SA installations.

As I already said, it looks like <whatever> is placing the correct new message-id
for that message in the wrong place and at the same time removes or doesn't add
the message-id there where it belongs.

Your headers are really very, very broken!

It surely has, you may just not notice it, because you are not that familiar with
how the thread should look like.
