Anyone having problems with emails from i cloud today?

I have an email address that ends in "me.com" as an iCloud Imap address in Mail and I'm not getting any of my mail this morning. I have tried to take the account 'offline' and then put it back 'online' ( which has worked in the past ) but not today.

I am logged into iCloud, and did the mobile me transfer of accounts months ago, so I am wondering:

1. Do I need to change any settings for my mac address ( change from "me.com" to another address?

2. Is there a general problem with iCloud mail today I am not aware of ?

My incoming mail server is : p04-imap.mail.me.com with SSL: ON

My outgong mail server is: p04-smtp.mail.me.com with SSL: ON

These settings were automatically configured when I set the mail account up originally.

Any help would be appreciated
