188196 - Improper view of folders in namespace when using courier-imap

Status: RESOLVED DUPLICATE of bug 80858

(MailNews Core :: Networking: IMAP, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2.1) Gecko/20021130

With courier imap, personal namespace is "INBOX.", "." is separator. INBOX
itself is user's inbox. When I open IMPA accounts, I see all folders as
subfolders of INBOX, but I think they should be at the upper level of hierarchy.
When Moizilla automatically creates folder (such as Sent), it creates it in
proper place (as "INBOX.Sent"), but shows it not as upper-level Sent folder, but
as subfolder of INBOX and does not mark it as Sent in folder pane until I
specifically point in account preferences that my Sent folder is INBOX.Sent
(subfolder Sent in INBOX). Also when I want to create new folder, Mozilla show
only folder INBOX in the upper level, but I can't create folders at the root of
hierarchy, but only subfolders of INBOX.

Reproducible: Always

Steps to Reproduce:
1. Create new IMAP account on Coureir-IMAP server
2. Add it to Mozilla mail.
3. Send letter using that account.
4. Try to create nes folder.

Actual Results:  
After step 3. a new folder Sent will be created and shown as subfolder of INBOX
and there will be a copy of sent letter.
During step 4. you will be able to create only subfolders of INBOX, but not root
folders.

Expected Results:  
New Sent should be shown in at the root level of hierarchy. (but it should be
created at the same place as it created now - Mozilla treats personal namespace
properly).
There should be possible to create folders (to show them) at the root level.

Here's IMAP command showing answer to NAMESPACE command from IMAP server.
