dovecot - Jan 2012 - dovecot imap cluster

Hello, i'm using postfix like smtp server, i need to choose an imap
server with a special features.

I have a customer with 3 different geographic locations.

Every locations have a mail server for the same domain (example.com).

If user1 at example.com receive mail form external this mail going on
every locations server.

I've a problem now, is it possible to syncronize the state (mail flag)
of user1 imap folder mails on every mail locations server?

Example, if user1 read a mail on server one is it possible to change
flag of the same mail file on server 2 and server 3?

Is it possible to use dsync for it?

I need something like imap cluster.

Or an action in post processing imap mail read.

I can't use distribuited file system.

Thank's a lot

Syncronize your storage with DRBD, (or async replica like rsync) and use dovecot
director for connection persistence.
