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.
