Hi All,

We are using Dovecot in a Director setup with two director proxies, six backend mailstores, mailbox storage in NFS, and user accounts stored in LDAP.   Currently we have five NFS filesystems on EMC VNX storage which are all mounted on each of the six backend mailstores.   At the moment all users could be directed to any of the six mailstores.  We have a group of users with very large mailboxes we want to put on separate cheaper Backblaze NFS storage.  Because this will be less reliable than our VNX storage we want to be able to direct this group of users to a new pair of backend mailstores that only have the Backblaze NFS mounts.   This would isolate the rest of the users isolation from problems with the Backblaze NFS servers.  I have read the Dovecot documentation which indicates it is possible to direct users always to a single backend server.    Can Dovecot direct users to a pair or more of backend mailstores - ie a subset or another set of mailstores.    If not it would be a great enhancement which would allow more scalability, flexibility and redundancy.

Thanks

Murray
