Albrecht,

I think this is the issue - a new item is appended to the list, until  
you do something to explicitly resort (clicking a heading or hitting  
Alt-V-J for JWZ threading) when it it moved to its appropriate place in  
the list.  I also see this witl mbox and maildir, the only types I  
currently use.  Opening a new folder also displays unsorted until you  
do any explicit sort.  I suppose caching the order would be even  
better, but at least sorting on opening a mailbox and not requiring  
explicit user action is what I would want.
