I have been happily using the mailing list mode across various
*.discourse.group hosted instances for a while now. However, something seems to have changed on or around Dec 6th (yesterday) such that my mail client is now acting as if each message in a thread is its own separate thread, which makes it much harder to follow the context of a conversation.
It looks like the problematic messages are using nonsensical
Date: Tue, 07 Dec 2021 08:09:36 +0000 From: "Foo via Racket Discussions" <firstname.lastname@example.org> Message-ID: <email@example.com> Subject: [Racket Discussions] [Questions & Answers] Lazy, yet opportunistic streams List-ID: Racket Discussions | Questions & Answers <questions-&-answers.racket.discourse.group> List-Archive: https://racket.discourse.group/t/lazy-yet-opportunistic-streams/369 Feedback-ID: racket:mailing_list:discoursemail
The email is about a topic from the
racket.discourse.group instance, but the
Message-ID on this one references
llvm.discourse.group, while all the other headers are correct.
