ICloud :: Mail Cannot Connect To IMAP Server

This morning, I started Mail as I do everyday, but I could not assess my iCloud mail.  I used Connection Doctor and the report that Mail was able to connect to the internet but under iCloud, the message was "Could not connect to this iCloud IMAP server.  Check your network connection and that you entered correct information in the Account preferences.  Also verify that the server supports SSL.  If it does not, deselect the "Use SSL" checkbox in the Advanced tab of Account preferences."  I checked the Account preferences and see the incoming Mail Server greyed out.  It said p03-imap.mail.me.com  I had been using Mail everyday and moved from Mobileme to iCloud once I upgraded to OSX Lion 10.7 several months back.  I have upgraded the OS to 10.7.3. 

I tried to assess mail in Safari and was successful.  I checked the iCloud status and it was on.  I did the following try to resolve the problem.  I repaired permissions.  I deleted the iCloud account from Mail.  Then I unchecked the Mail & Notes checkbox in the iCloud pane in System Preferences.  I restarted the computer and rechecked the Mail & Notes check box in the iCloud pane in System Preferences.  Then opened Mail and opened it Preferences.  Then I added one account.  Filling the Name, email address and password in the form.  When I pressed continue, I get the message, "The iCloud IMAP server 'p03-imap.mail.me.com' is not responding ..."  At the moment I am using the browser to assess my mail.  Is there some way to get back assess in Mail?
