iPhone 6: I can send mail, but cannot receive mail
I have tried using the manual approach as well as retried with the profile tool, and both ways produce the same result. I can compose an email and it gets delivered, but I cannot receive emails. The sender keeps getting a message about it not being able to be delivered. "Action: failed ... Status: 5.0.0". Then I got another that says "550 High probability of spam".
Any suggestions?
