I recently installed the 2007e of UW IMAP and seeing high I/O wait on the server.
What, specifically, do you mean by "high I/O wait"?
I have about 50 users.
That is a very small facility that even modest server hardware should handle with aplomb.

This message simply means that a client disconnected from the server without first issuing a proper LOGOUT command, and that this was detected while the server was reading a new IMAP command line. The only time this message is at all interesting is if a user complains about being disconnected from the server. This message is evidence that, from the server's viewpoint, the client disconnected. This means that you can dismiss the server as a possible cause of the problem, and look elsewhere. When both client and server point fingers at each other, a common cause is an intermediate router (especially a NAT).

None of these messages are remarkable. They are all indications of normal operation. Your /etc/xinetd.d/imap file looks OK as well
My initial build was like this: make lr5 SSLTYPE=none
Why are you using SSLTYPE=none? I hope that this is strictly for in-house use, and not exported over the Internet; as it will result in confidential traffic (including passwords) being sent in the clear. -- Mark -- http://panda.com/mrc Democracy is two wolves and a sheep deciding what to eat for lunch.
