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?

I don't have an immediate answer for you, but I can tell you that many of my clients who use Rogers Internet received a notice recently telling them that new updates to the way their mail works will requires that they update their Outlook email configuration.

Here's the online notice:

Rogers uses Yahoo! as their email provider which is why I think this is relevant to you.

So far as I can tell, the change was just that they are now requiring that you use SSL encrypted connections w hen connecting to your email. Unencrypted connections will no longer be supported.

I don't see any reason why this wouldn't work with the SBS POP3 connector, even if Yahoo doesn't officially support it.

Is there any more detailed information you can find in the event logs? Maybe an error number?

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)

Sorry GadFriedman... I don't have an answer for you.

If it is working in a standalone client like Outlook, an identically configured POP3 connecter OUGHT to work. I don't know why it isn't and I don't know how to debug the problem further. Maybe if there were some log files or something in the event log we could use to troubleshoot further....

Only thing I can suggest is maybe try using a different, third party POP3 connector such as POPCon.
