Sorting / threads not supported for default imap capabilities

[simonbuehler]

Hi,

when trying to connect to the ionos IMAP server, I get this listing of capabilities:

. capability
* CAPABILITY IMAP4rev1 CHILDREN ENABLE ID IDLE LIST-EXTENDED LIST-STATUS LITERAL- MOVE NAMESPACE QUOTA SASL-IR SORT SPECIAL-USE THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN APPENDLIMIT=140000000
. OK CAPABILITY completed

see the THREAD=ORDEREDSUBJECT definition - I unchecked the "Threads" options but still, now in the settings tab i get this view:

is the provider really that limited, or did I configure something wrong?

I will look into it as the new feature conflicts with some old THREAD behavior.
