[Dovecot] LSUB strangeness continued

[Don Steiny]

Hi,

 I wrote earlier to mention that I am having touble with LSUB command
reporting "permission denied'  on some accounts and not others that are
identical as far as I can see. 
I am trying various combinations of stuff, so i set up a new IMAP
account in Thunderbird that went to one of the accounts I am having
trouble with. I was not surprised to get "Server says permission
denied".  I was surprised that after a minute or so, it went ahead
downloaded the mail messages? What the heck?  Does Thunderbird try
another command?
