For what it's worth I tried putting your example mailboxes into my own 
mailboxes list for one of my accounts and this cleared up when 
synchronizing the account. In other words, the problem was very likely 
related to the unexpected NO responses from your server. I'll note to 
test what happens in this case and see if the response can be improved.
