Threads are not working

[nicofrand]

Hi,

I am using an IMAP account provided by OVH (Email pro solution) withing SnappyMail.
When I answer an email the answer appears at the top of the list and the initial email and the answer are not collapsed into a thread.

In the UI there is a button saying the server does not allow sorting (French translation of "[title]MESSAGE_LIST/NO_SORT").

But in other webmails (ex: OWA, which is provided by OVH, or K9 on Android) it works fine.

How can I debug/solve it?

Maybe this helps?

If you look at

snappymail/dev/View/User/MailBox/MessageList.js

Line 114 in 49010a7

sortSupported: () =>

and the following lines there, your IMAP must support the "SORT" capability... Probably (not 100% sure) the fact that OWA and other clients work is simply because these implement a own sorting that does not use the IMAP sorting feature...

Yeah, I was hoping there would be a fallback.
There is no way my provider implements it 😞
