It seems Yahoo Mail hosting has made a change to their POP mail security. Our SBS 2008 POP connector errors out saying that it cannot authenticate the email accounts. If I take the EXACT same settings (server name, SSL port 995) in a standalone POP client (eg. Windows mail, thunderbird, etc.... ) it will connect. I contacted Yahoo and their answer was "Sorry but as of last week we only support standalone clients, not connectors" The thing is every so often it will go through and autheticate but then stop. Why won't the SBS pop connectors authenticate against Yahoo servers now?
