I called Apple . Got supervisor Carla. She did a conference call with Go Daddy . Had the problem previously with someone else. Godaddy tried to fix by changing pop numbers nothing worked. They then proceeded to change my POP to Imap and it worked immediately all mail was working. I had to pay $44 to go daddy good till 2017. Price will go up. That was my only choice or I would have to use another email service. That was no option for me. Mac email did not work with the pop server after El Capitan update on Mac.
