Hotmail smtp.live.com server will not connect
Since yesterday Mail on my iMac will not connect with the Hotmail smtp.live.com server for sending e-mail. Whenever I try and send I get amessage saying the server is offline. I've made no changes to the machine which is running 10.8.2. I've tried deleting and recreating the account -- no joy. I've tried different port settings and SSL is selected I've tried setting up the account on another Mac, still no luck. But setting up Hotmail in Microsoft Entourage works fine. Google mail and Yahoo mail also work fine in Apple Mail.
Can anybody help? Thanks.
