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

Probably not much of a problem.> But, if they're private, they have to be stored outside the filename : how can we do that ?Currently you can't. Although changing the code to support it probably wouldn't be too difficult. I need some kind of a design plan for this some day. :) -------------- next part -------------- A non-text attachment was scrubbed...

Probably not much of a problem.Why not much of a problem ? Sure there will be only one mapping but cannot the keyword meaning be different between different user agent of even the same user ? Can't we end up in a message tagged as "important" in a client being tagged as "personnal" in another client ? -- Thomas Hummel | Institut Pasteur <hummel at pasteur.fr> | P?le informatique - syst?mes et r?seau
