You need to go back to the basics.

   (1) What does Squid record in the access.log when you get a failure
        to log on or off?
   (2) Was the failure caused by evaluation of the regular expression
        or was the error status returned by HotMail or Yahoo!?
   (3) What is in the logon or logoff JavaScript that would trigger
        Squid to return an error status?
   (4) Does the error only occur when you are redirected to a specific
        HotMail or Yahoo! server?

You may need to turn on the capability in Squid to record the parameters
passed in the request. The trigger event may be in a session control
value that is being passed in a parameter. It would not be unusual for an
encrypted value to contain one of the strings in your block text.
