Hi, i've a simple question, what do you mean for dovecot director setup? 'i've a doubt. The solution that i'm testing is using 3 mail server in different geoghrapic locations. An user can travel in varius location, and i want his imap mail reside on mail server in every locations. Sò i use you solution about replication. First server (by dns record) that receive mail sync it on the other servers, and when user consult is mail by imap protocol everything is sync on all servers. Do you suggest to use a horizontal structure for it like i explain or is better to have a single node external mail server and customer locations server like slave?
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..
