I don't see this message on the list, so I'm attaching the patch in my reply

Currently I have no time to test it well, but I've seen the patch and 
I've got a few thoughts:

1. threads support detection and thread algorithm auto-selection. I 
think 'imap_thread_algorithm' should be set automatically to the best 
from those supported by server (REFS, REFERENCES, ORDEREDSUBJECT). It 
means if e.g. server supports REFS and ORDEREDSUBJECT we should use 
REFS. Does anybody need ORDEREDSUBJECT if he's server supports 
REFERENCES? Also see manage_folders.inc for: 

2. Don't use massage_sort_col='default'. Since we have 'index_sort' 
option. Messages are sorted by message index if message_sort_col='date'.
We don't need this 'default' stuff also because THREAD command returns 
messages sorted by date.

3. We also wouldn't need enable_thread_caching option. Use 
enable_caching instead. I know it will be hard now, but for me would be 
better (a much better) to remove the whole thread caching stuff from the 
patch and implement this in next step after threading will be working 
well without caching. For first step: enable_caching=true -> 
messages_treading=false. I'm of course a volunteer to implement the 
whole threads caching stuff.

4. Maybe list.js changes could be more universal. E.g. expand_unread()
could be implemented as expand_by_state('unread') or sth. The list.js is 
used not only for messages.

5. In mail steps use short $IMAP instead of 
rcmail::get_instance()->imap->threading. Just for better readability.
