Looks good. Maybe there should be "#shared."? If cyrus does support NAMESPACE these options can be set to null (re-login required). Enable imap_debug in Roundcube and show as the log.

Hi Alec,

The relevant log is:

[15-Dec-2010 16:01:44 +0100]: C: A0003 STATUS INBOX.shared.testshared (MESSAGES UNSEEN) [15-Dec-2010 16:01:44 +0100]: S: A0003 NO Mailbox does not exist

I am not sure the $rcmail_config['imap_ns_shared'] is working properly, or maybe it doesn't detect that "shared.testshared" is a shared mailbox. I tried to set it to the following value with no success (it always look for INBOX.shared.testshared):

$rcmail_config['imap_ns_shared'] = "shared.";

$rcmail_config['imap_ns_shared'] = "#shared.";

$rcmail_config['imap_ns_shared'] = null;

$rcmail_config['imap_ns_shared'] = "";

On login, the CAPABILITY command returns the following:

[15-Dec-2010 16:12:20 +0100]: C: A0003 CAPABILITY [15-Dec-2010 16:12:20 +0100]: S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE IDLE LOGINDISABLED [15-Dec-2010 16:12:20 +0100]: S: A0003 OK Completed [15-Dec-2010 16:12:20 +0100]: C: A0004 LSUB "" "*" [15-Dec-2010 16:12:20 +0100]: S: * LSUB () "."

It properly lists the shared mailbox. However, it doesn't check the number of unread messages in that mailbox.

This option is not used when IMAP server supports NAMESPACE...

...

[15-Dec-2010 16:12:20 +0100]: C: A0003 CAPABILITY [15-Dec-2010 16:12:20 +0100]: S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE IDLE LOGINDISABLED

...and your server does support it. So, do re-login in Roundcube (it's required because namespace settings are stored in session) and check in the log what is returned for NAMESPACE command.

Here it is:

[16-Dec-2010 14:53:57 +0100]: C: A0003 NAMESPACE [16-Dec-2010 14:53:57 +0100]: S: * NAMESPACE (("INBOX." ".")) (("user." ".")) (("" "."))

I'm not familiar with the namespace command, but if it wasn't working properly, it shouldn't see the shared folder in roundcube. right ?

It should probably return:

• NAMESPACE (("INBOX." ".")) (("user." ".")) (("shared." "."))

So, maybe you should ask on cyrus' mailing-list.

I'll ask them. I'm currently reading the RFC of the NAMESPACE extension.

However, how do you explain that Thunderbird can access the shared mailbox just fine (read, write, delete, ...) ?

It is a problem in Roundcube, agreed. We have a few possibilities of fixing this on Roundcube side:

1. We could detect such situation and handle folder names correctly.

E.g. when parsing LIST/LSUB response we should check folder prefix if doesn't exists add it to shared namespace (internal) definition. This will not work if personal namespace doesn't use prefix.

2. We could make imap_ns_* options (if defined) to overwrite namespace

response from server.

3. We could change folder names handling, so personal namespace prefix

will be not removed (could be removed for display only). More work. Probably not backward compatible change.

None will be needed when you fix namespace response.

You can open a ticket in trac pointing to this thread.

I started the discussion on the cyrus mailing list: http://lists.andrew.cmu.edu/pipermail/info-cyrus/2010-December/034249.html

I suppose your second option (overwrite namespace response) would be preferable. Sysadmin are used to configuration options that force a specific behavior, it's less confusing.

I don't know yet if it's roundcube, cyrus or me that is responsible for this problem. I will investigate and file a ticket if necessary. However, if you had a quick patch to overwrite namespace response (or indicate me where to do the change), I'd appreciate.

Thanks, Julien

Back to the original discussion. It appears that cyrus's altnamespace option shouldn't be used for this (it's considered an ugly fix).

It also seems that this bug is purely roundcube related...

Does anybody else use cyrus imap, roundcube and shared mailboxes ?

Below is the quote of my last email on the cyrus mailing list:

See RFC 2342 for the specification on what the NAMESPACE response

issue. A mailbox named 'testshared' would also fall under the shared namespace.

That mailbox would correctly be returned as 'shared.testshared' with altnamespace turned off, and 'Shared Folders.shared.testshared' with it turned on and 'sharedprefix' configured with 'Shared Folders',

which is the

Both cases are correct and a compliant IMAP client should handle

both. In

neither case should the mailbox be searched for under the personal name space, which roundcube appears to be doing.

I just tried to create a mailbox without the 'shared.' prefix, as follow:

# cyradm --user cyrus localhost Password: localhost> cm shrdmailbx localhost> sam shrdmailbx anyone p localhost> sam shrdmailbx julien lr localhost> sam shrdmailbx michel lrswipcd localhost> quit

I set altnamespace:no and restarted cyrus. The result is the same as before. I can subscribe and access the mailbox from thunderbird, but I can't from roundcube.

When i set altnamespace: yes and restart cyrus, I can access the mailbox 'resgate' from roundcube.

I will forward that information to the roundcube's mailing list and work with them to solve the issue.

Thanks for your help

Julien
