IMAP Internet Problems

I noticed other people are having problems when deleting emails. I have had Windows Live Mail for the last several weeks and have been getting error msgs when reading/deleting emails like: "Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems or a long period of inactivity. The server did not respond to this IMAP command before the connection was terminated." and "Your IMAP command could not be sent to the server, due to non-network errors. This could, for example, indicate a lack of memory on your system." My read emails appear unread. Emails either can't be deleted or they reappear in the inbox after I delete them. I've talked to Cox Tier 2 support, who recommended uninstalling the Webroot antivirus and installing Cox's McAfee. I've done this and I still get error msgs. I've had the Best Buy Geek Squad out twice to try to fix this and they believe the problem is with Cox. From this forum, many people would agree. What is Cox doing about this problem?
