Announcement message with different message ids (was: ANNOUNCE: garcon 4.17.2 released)

Dear Xfce folks,


Sorry for the messages. Luna’s reply from Mon, 31 Oct 2022 17:11:07 +0100

     Message-ID: 
<CADo9pHguAwpWbPegPCACfCS_Rt1MFWV-xXKobm1Te1cifkhTAg@mail.gmail.com>

was incorrectly threaded, and I tried to find out, why the announcement 
message seems to have a different message id, than the one I received 
over the discussion list [email protected]. Therefore, I asked for a forward 
as attachment to inspect the message headers. It looks like Google Mail 
makes that very hard.

Anyway, Gaël, did you write two separate messages to [email protected] and 
[email protected]?

It’s not a big issue.


Kind regards,

Paul


PS: My original query to Luna:

Your reply was incorrectly threaded in my Mozilla Thunderbird, and it
turns out you seem to have received a message with a different message
id. Your reply contains:

      References: <[email protected]>
      In-Reply-To: <[email protected]>

The message I got from Gaël Bonithon has the id:

      Message-ID: <[email protected]>
      […]
