Email account problem

[68bucks]

I discovered today that my Yahoo email account isn't working anymore. I try to sync and get nothing. I re-entered the account password and I get a error message saying "cannot safely connect to server." I'm not sure what that is all a bout but does anyone have any ideas what the issue might be? Had this for a couple years without a problem.
