Hi,

I think option-2 below seems better or am I missing something with director concept.

1. As director and back-end in same server (broken) not recommended, I need minimum 4 servers (2 for director, 2 back-end IMAP). Indexes and mail must be in NFS shared storage(not optimal), as a user may land on any of the back-end servers (assuming no static mapping of user from pass DB).

2. Proxy_may in passDB (static mapping of users to servers makes balancing little partial but can be admin optimized) can achieve the above setup with 2 servers without director. Here indexes can be on their local disk (efficient)  and mail on shared storage (NFS).

Both case I can use RR DNS to get users IMAP traffic to front end. Any guidance on this is appreciated.
