Right. > 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).

If you want per-user flags and want to share indexes, you need the new INDEXPVT option that exists in v2.2 or as a patch to v2.1: http://dovecot.org/patches/2.1/private-index.diff > 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 they are outdated.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? INDEXPVT is a requirement with dbox if you want per-user flags. BTW. Do you have multiple Dovecot backend servers? Director works only when you're not using shared mailboxes..
