Unable to send email, but can receive
My wife's Yahoo email was hacked or something the other day, sending out "please help me with money, I'm stranded in Britain" messages to everyone in her contact email list. She changed her password immediately afterward, but ever since then she can't send email from her iPad 3 (she can receive fine), even though she can send/receive from our laptop with no problem. Whatever happened, it deleted everything in her inbox and sent boxes, so it was malevolent. I hope that's all it did.
I verified that she changed her password in Settings on the iPad, but it made no difference. I even had her delete her Yahoo email account on her iPad, then recreate it, but she still can't send email.
Could this be a virus or something on the iPad? It seems to be iPad-specific since she can send email fine on our home computer.
