Dovecot director isn't really meant to be used for geographic user distribution. Also the replication doesn't yet support more than two servers. A master-slave setup wouldn't have the UID conflict problems that multi-master dsync replication has, but the UID conflicts probably won't be a big problem. Anyway, difficult to give recommendations about an unfinished feature..
