Yahoo in Mac Mail not logging in since upgrade to El Capitan
Things were fine with Yahoo in my Mac mail in Yosemite.
I have now upgraded to El Capitan and all mailboxes are blank and I'm getting a login error.
I have completely reset Mac Mail and have tried to add the account from scratch and I just keep getting the login error. I am copying and pasting my email and password credentials which I know are correct as I use them to log into webmail.
Anyone else having glitches with Yahoo and Mac Mail in El Capitan?
iMac, OS X El Capitan (10.11)
