Suddenly my me.com mail won't work. It shows the zig-zag line next to iCloud. Sending emails works but it doesn't receive emails.
I'm using apple mail, on OS X Lion.
The other account (gmail) is fine.
I can only receive my me.com mail by going into safari & putting in my password each time.
I can't think of anything I've done to cause this.
Rebooting doesn't help.
I'd be grateful for help.
