89032 - IMAP folders that are not assigned to a namespace are not displayed.

Status: RESOLVED WONTFIX

(MailNews Core :: Networking: IMAP, defect)

Description

[Boldra]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:0.9.2) Gecko/20010628
BuildID:    2001062823

When viewing incoming mail, only folders created using mozilla are displayed. 
This is consistant accessing the same IMAP account via linux (v09.2) and windows
(0.91).

After 4 restarts of mozilla (from when mail settings were created), the problem
resolves itself (only on one platform).

This behaviour did not occur with milestone 0.8 linux, but with 0.91 linux and
0.92 linux.  

IMAP server version:
"* OK dot.dreamhost.com IMAP4rev1 2000.281 at Tue, 3 Jul 2001 04:57:58 -0700 (PDT)1"

This may be related to 13472 ?

Reproducible: Always
Steps to Reproduce:
1.Create IMAP folder
2.do fresh mozilla install
3.configure mail and check folders.  Folder will be invisible.
4.shutdown mozilla (completely)
5.check mail (2)
6.shutdown mozilla (completely)
7.check mail (3)
8.shutdown mozilla (completely)
9.check mail (4)
10.folder is now visible


Actual Results:  Folders created before mozilla was installed were invisible
(mozilla rejected attempts to create duplicate folders - so they WERE REALLY THERE)

Expected Results:  folders should have been listed

I have a little lemon juice on my nose.

Very thorough report.   Marking NEW.

Well,

* Environent
- My team (5 persons) & I used the successive builds of Mozilla on Win2k pro
clients since june. Server : Debian Potato + Univ. Washigton Imap server (no
SSL), 100 Mb LAN with no charge.
- Very intensive use, in prod.
- use is maybe strange : we have each X accounts opened on the server. Each
account can be opened simultaneously by several clients with the same login /
pass. I dunno if it is legal... No time to check !
- Imap server / folders are perfectly accessible under Eudora 5.1 : quick and no
issues, in the same conditions => server OK.
- We have "huge" collections of folders / subfolders in a box (more than 1000
subfolders in a 4 levels tree). Each folder is generally 20-400 kbytes, some few
reach 5-9 Mbytes. Subfolders names are normalised (for instance: 2001-09:0012).
Yes, we run a help desk by Email.


* What we all see :
A kind of persistent "cache" issue while browsing the folders trees. As if the
mail client was keeping persistent info of subfolders trees, and keeping it
often false ! No way to refresh it !
1) Folders tree is incredibly slow to scroll and print on the screen, especially
when the folders list is refreshed (just WAIT, team !).
2) Some folders containing subfolders will not display those on some PCs, and OK
on others. Sometime, they will not display all although some subfolders will appear.

=> general issue while refreshing the folders trees on big trees. I once solved
it on a PC by reinstalling completely Mozilla (with the same version).

I look forward to answer all questions that would seem relevant.
Regards.

I have similar problems of folders not showing. I can provide logs if needed.

Severity should not be minor. This is major or critical !!!

There was bug logged today -> bug 111018.

Comment 5

I recently installed 9.6 on a win2k machine, and I have this problem again,
but now my work-around (restarting three times) is not helping.  Without a work-
around, this bug is serious.

In my new situation, only five of my 14 folders are displayed.  Curiously, I am 
now having an almost identical problem with star office.  Below is the list as 
returned by a telnet 143 session with "list all" on my IMAP server:
--
1 list "*" "%"
* LIST (\NoInferiors \Marked) "/" sent-mail
* LIST (\NoInferiors) "/" sunrise
* LIST (\NoInferiors \Marked) "/" zurich
* LIST (\NoInferiors \UnMarked) "/" thechat
* LIST (\NoInferiors \Marked) "/" ppl2
* LIST (\NoInferiors) "/" Sent
* LIST (\NoInferiors \Marked) "/" family
* LIST (\NoInferiors \Marked) "/" elan
* LIST (\NoInferiors \UnMarked) "/" chisholm
* LIST (\NoInferiors) "/" ppl
* LIST (\NoInferiors) "/" boldra.com
* LIST (\NoInferiors \UnMarked) "/" curio
* LIST (\NoInferiors \Marked) "/" Trash
* LIST (\NoInferiors) NIL INBOX
1 OK LIST completed
--
Of the above folders, "INBOX", "ppl2", "Sent", "sunrise" and "Trash" are the
only ones which display in mozilla and star office (No, I'm not asking for
anyone's help with star office).

If someone with a bit more C knowledge than me wants to take this on, I'd be
happy to setup an imap account on my server to help investigate this.

I installed a packet sniffer on my NT box today to see what it is that mozilla  
says that fails to return the folder list.  Here's a copy (username/password 
changed)
-------------------------
1 capability
2 authenticate login username password
3 namespace
4 lsub "" "*"
5 lsub "" "#mhinbox*"
6 lsub "" "#mh/*"
7 lsub "" "~*"
8 lsub "" "#shared/*"
9 lsub "" "#ftp/*"
10 lsub "" "#news.*"
11 lsub "" "#public/*"
12 list "" "INBOX"
13 select "INBOX"
14 UID fetch 1:* (FLAGS)
15 UID fetch 928,1453,1890:1891,1970:1971,2004:2005 (UID RFC822.SIZE FLAGS 
BODY.PEEK[HEADER.FIELDS (From To Cc Subject Date Message-ID Priority X-Priority 
References Newsgroups)])
-------------------------
Now the crucial commands here appear to be #4 and #12.  On my IMAP server, 
command #4 does not return all of the folders.  It only the ones I mentioned in 
my last update.  So the folders that are being displayed are /only folders that 
belong to a namespace/.

This shouldn't be a problem except for #12.  I'm not sure why #12 is being run 
at all, since any subfolders of INBOX would have been displayed during #4.  
Instead of finishing the mailbox scan with a search for sulbfolders of the 
inbox, surely the last command should be something like <<12 LIST "" "*">> to 
list any folders that do not have namespaces?

CCing to myself

Comment 8

[Jeremy Howard]

Turning off 'show only subscribed folders' in the UI should resolve this problem.

Comment 9

[Henry Jia]

Reason for this bug:
Defaultly, mozilla only shows the mail folders that are subscribed. When mozilla
create a mail folder, it automatically subscribe this folder. When you use 'list
"" "*"' command, you'll get all the folders, including the ones you subscribe.
The ones that are not subscribed by you will not be shown in mozilla.

Workaround:
Subscribe the folders you want to show in mozilla.

Mark the bug WONTFIX. If something new found, we can reopen this bug.

I have very similar problem (see #147528) with the MS Exchange 2000 IMAP server. 
Turning off 'show only subscribed folders' in the UI do not resolve it. In fact
 I've always had 'show only subscribed folders' off, but I've tried to play with
the option and folders subscribing/unsubscribing... but without any results. I
can only switch visibility of hi-level subfolders, but deep-nested subfolders
are always invisible (in ALL UI places - mail folders pane, Subscribe dialog and
pop-up Copy/Move messages menu).
