[Dovecot] flags, keywords in a shared mailbox setup

[Thomas Hummel]

Hello Timo,

I'm trying to get a clear understanding of dovecot's (1.2.x) flags and keywords
sharing possibilities or impossibilities in a shared-mailboxes setup.

By definition, a shared mailbox is a mailbox from a personal namespace which
has been made available to someone else who sees it in a shared namespace.

There can be some combinatorics according to the fact that INDEX and CONTROL
files location can either be user-dependent or user-independent and this in
either the private or the shared namespace.

Besides, it's not clear to me if the 'dovecot-shared' file is still relevant in
1.2x and shared-namespaces to store flags only in indexes.

So what combination is to be avoided because it would break things ?

More specifically :

  . is, in 1.2x, the method for having private flags of a shared mailbox still
    to have the 'dovecot-shared' file (in order to store flags in indexes) ?

  . how can shared keywords in a shared mailbox even work ? If they're shared
    (how ? by pointing CONTROL to the same user-independent location ?), keywords
    known by a client (user1) won't necessary be known or have the same meaning for
    another client (user2), will they ?

    [Note : isn't it the same event with no shared mailboxes but with one user using several clients ?]

    But, if they're private, they have to be stored outside the filename : how can we do that ?


Thanks
