Some of the Outlook clients are losing connection to the server with Outlook reporting "Courier-IMAP server shutting down". Looking through the source, this only occurs when the client sends a LOGOUT message. Syslog shows LOGOUT for that user. Any idea why this may be occurring? Outlook gives a message suggesting connection was lost, possibly due to timeouts. I see the client opening two or three simultaneous connections when it starts up.
Also, is there any way to log the traffic to/from the IMAP server so I can trace this further?
