About a week ago I noticed that my emails we're not being sent from my yahoo account to my iPhone 6. Subsequently, I tried all the fixes to get the email pushed from my Yahoo account to my iPhone email. I realized later, that the problems began likely after I had completed my IOS 8.1.3 update. I have tried deleting and adding the yahoo account from my iPhone, I have gone to Yahoo and checked all my settings. I have reset my password for my Yahoo account and nothing corrects it.
