[Dovecot] shared mailboxes and indexes

[Angel L. Mateo]

Hello,

	We are deploying shared mailboxes in our mail system. We are running 
2.1.9 and mail backend is maildir.

	As described at http://wiki.dovecot.org/SharedMailboxes/Shared when 
shared namespace is configured as

namespace shared {
   separator = /
   prefix = shared/%%u/
   location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u
   subscriptions = no
   list = children
}

	each user accessing this folder has its own index, stored in 
~/Maildir/shared/%%u/<shared mailbox>, hasn't it?

	Our mail is store in NFS disks so we are very concerned about indexes 
optimizations (we had performance problems until we got all of our 
indexes and nfs tunned). So, is there any way so those indexes could be 
shared for all users (and they always would be updated).

	Regarding this... if we'd use dbox instead of maildir, indexes are a 
really important part of the mailbox and they can't be re-constructed 
when they are outdated. So, how do shared mailboxes work with dbox 
backend? Do I have to configure indexes in any particular way?
