Is Dovecot Director stable for production??
Today I will try Dovecot Director for a setup using a Cluster Backend with GFS2 on rhel5, my question is if is Director stable for use in production for large sites, I know is mainly designed for NFS but I believe it will do the job also for a cluster filesystem like GFS2 and should solve the mail persistence problem with a node and locking issues. I plan to add a layer behind a load balancer to
