SBS POP 3 connector not authenticating with Yahoo Small Business POP

Hi,
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?

In The event viewer for the pop3 connector I am getting the following message:
The credentials provided for user account "XXX@XXXXX" on the server "pop.bizmail.yahoo.com" are incorrect. Verify the user name and password for this user account.


If I take the exact same pop3 settings (username, password, server, port 995, SSL) and Enter them into a standalone client like Outlook, Win Mail or Thunderbird. It works.  The POP connector had been working fine. Yahoo Small business posted a down message last wednesday (which is when this started occuring) and after a day said there issue was fixed, but I have not been able to pull mail through the SBS connector since (with a couple rare exceptions where it might work once and then go back to the above error)
