 Ok, just committed it, even if it is still the very ugly version.
It's bad that I do not have a normal inet connection, and when I have
I have to do a lot of things. :-( Anyway, it should work, as it works
for us for two weeks now.

 Could you sort the jokes folder to a dummy user? So privacy won't be
affected, only john and ronin also have to add this dummy user's mailbox.

 I do not know how it is implemented, I will try to look into it. Please
do not expect it soon, as it seems I am the only active(?) developer
nowadays, without enough time/inet access. Thus what I do is more than
stablise the code nowadays, do a release and just after add new features.

 Yup, this is the scenario.

 Fixed a session timeout problem right this time. Before it was buggy,
logged an entry/second/user that the session is timed out indefinately.
It caused very large log files under short period of time so it was a
showstopper. Now I am still not pleased (see the logout, how empty
user is constructed in case of null session), but it fixes the problem,
and later we can work on the internals to do it in the rigth way tm.

If I understand this correctly he wants to have a shared folder for jokes?

so normally:
user.someuser - is the inbox
user.jokes - shared jokes folder?

JWebMail only allows us to add folders from that point on in the hierarchy?

What was the change you committed?

Well, jokes was an example, I want to share more folders :-)

I will write a more elaborated (almost real) example. Let be:
- Cyrus is the imap server.
- "cyradm" is the administrator tool for Cyrus.
- "lm" is the command to list mailboxes.
- "lam" is the command to list ACLs on mailboxes.
- "boss" is the cyrus imap administrator.
- "ronin" and "john" are two mail users.

[ronin@www ronin]$ cyradm --user boss localhost
Password:
localhost.localdomain> lm
user.john (\HasChildren)
user.john.sent (\HasNoChildren)
user.ronin (\HasChildren)
user.ronin.sent (\HasNoChildren)
user.ronin.jpackage (\HasNoChildren)
user.ronin.jwebmail (\HasNoChildren)
user.ronin.mandrake (\HasNoChildren)
user.ronin.homecinema (\HasNoChildren)
localhost.localdomain> lam user.john
john lrswipcda
localhost.localdomain> lam user.ronin.jwebmail
john lrs
ronin lrswipcda

With Cyrus, each folder has ACLs, so you can set permissions on it in order to 
give different permissions to different users. In the example, "ronin" has 
set read permissions for "john" on his folder "jwebmail". That folder is the 
destination for a mailing list where "ronin" is subscribed. He can write on 
it, but "john" is able to read the messages in that folder too, although he 
can't delete them or put new messages. If "ronin" login in "cyradm" as 
himself he only see his folders:

[ronin@www ronin]$ cyradm localhost
Password:
localhost.localdomain> lm
INBOX (\HasChildren)
INBOX.sent (\HasNoChildren)
INBOX.jpackage (\HasNoChildren)
INBOX.jwebmail (\HasNoChildren)
INBOX.mandrake (\HasNoChildren)
INBOX.homecinema (\HasNoChildren)

But if "john" login in "cyradm" he can see other folders if he has the rights 
to do that:

[john@www john]$ cyradm localhost
Password:
localhost.localdomain> lm
INBOX (\HasChildren)
INBOX.sent (\HasNoChildren)
user.ronin.jwebmail (\HasNoChildren)

Here is the problem, with jwebmail he can only see folders inside his INBOX, 
so he is not able to access jwebmail folder.
Regards.

	Yes, but both users will have the same privileges, and I want that only user 
"ronin" can add jokes to the "jokes" folder :-)

	Thank you very much!

Re: [Jwebmail-devel] IMAP folders with cyrus

[Brett F. <br...@fo...>]

Ok I've looked at the code and at the JavaMail API. Mind you, I've never=20
used the JavaMail API so I'm no expert! Any ideas?

Currently on connect the future is fixed with:
Folder f=3Dst.getDefaultFolder();

Which is defined as:
*javax.mail.Store*
public abstract Folder <../../javax/mail/Folder.html>=20
*getDefaultFolder*() throws MessagingException=20
<../../javax/mail/MessagingException.html>
Returns a Folder object that represents the 'root' of the default=20
namespace presented to the user by the Store.

Looking at the java documentation I see three(!) other functions that=20
should probably be used in place of getDefaultFolder. (So the code in=20
JWebMail for "searching" folders is redundant? and broken? Why implement=20
something already provided by the API? It also implies that it is=20
impossible to access the shared mailboxes unless it's the default=20
namespace.)

*javax.mail.Store*
public Folder <../../javax/mail/Folder.html>[] *getPersonalNamespaces*()=20
throws MessagingException <../../javax/mail/MessagingException.html>
Return a set of folders representing the /personal/ namespaces for the=20
current user. A personal namespace is a set of names that is considered=20
within the personal scope of the authenticated user. Typically, only the=20
authenticated user has access to mail folders in their personal=20
namespace. If an INBOX exists for a user, it must appear within the=20
user's personal namespace. In the typical case, there should be only one=20
personal namespace for each user in each Store.

public Folder <../../javax/mail/Folder.html>[]=20
*getUserNamespaces*(java.lang.String user) throws MessagingException=20
<../../javax/mail/MessagingException.html>
Return a set of folders representing the namespaces for |user|. The=20
namespaces returned represent the personal namespaces for the user. To=20
access mail folders in the other user's namespace, the currently=20
authenticated user must be explicitly granted access rights. For=20
example, it is common for a manager to grant to their secretary access=20
rights to their mail folders.

public Folder <../../javax/mail/Folder.html>[] *getSharedNamespaces*()=20
throws MessagingException <../../javax/mail/MessagingException.html>
Return a set of folders representing the /shared/ namespaces. A shared=20
namespace is a namespace that consists of mail folders that are intended=20
to be shared amongst users and do not exist within a user's personal=20
namespace.
