Thank you for the detailed analysis, the threading issue you've described is a known problem with the current mailing list infrastructure. We're planning to migrate all mailing lists to Groups.io, and this issue will be resolved as part of that migration.

We'll share more details and the migration timeline once everything is finalized

Hi

For several month the mail threading on this list broken and making the list hard to read. It can easily be seen by looking at the archive, in this link for about 9 mount(as of writing)

https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/latest?count=10&page=100

...

Subjects all have nice subject without "Re:" for replay, and on the right you see how may people(person icon) in the thread and number of post(talking bubble) in the thread.

But if we look at more recent posts like this one

https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/latest?count=10&page=1

...

you see a lot of "Re:" in the subject and most of them have one person and only one post because the threading is broken.

Take this recent mail "Weird behavior for 2 OSDs in our cluster" The fist mail by Wannes Smet

https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/62B63BH33F3U...

...

when i check my mail client this mail has following ID. "Message-ID: <

0100019e7c77595f-ffb4d04b-1771-46cf-8b60-10795bc6a1c5-000000@email.amazonses.com

"

The reply from Eugen Block

https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/E63Z3JR7DMSS...

...

the header says this is a reply to different ID "In-Reply-To: <

0100019e7c7979e5-8d4d96e6-1c93-4a76-a5cd-efdf25ada853-000000@email.amazonses.com

...

...

"

When I search the header of the mail from Wannes Smet I find no such ID that is in the In-Reply-To.

It looks to me that the mailing-list server is sending different "Messages-ID" to the members on the list. This should be the same or the threading breaks as we can se.

Can this be fixed please?
