I think SAN is way out of reach of somebody who is left to build mail server for 2000 users with only 40GB drive. Anyhow, what if your SAN storage or NFS server goes down? Your mailboxes go down with it. Hm, not much difference there. You are just replacing one component that might fail, with another component that might equally fail. This is a rahter complicated issue, and there is no single way to implement it. Courier works for some folks. Cyrus works for some folks. They are both good. You choose one and after some time learn to live with its limitations. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
