Failed emails sent via BT Yahoo

[Estreet17]

I am now with Sky but have retained my old BT Yahoo email account, I have tried to send an email today on 3 occasions but each time it has returned & the reason seems to be my email account. I have rang BT & sent an email to them which they confirmed they have received so they say they can't help any more? I don't know where to go/who to contact to get this sorted. Can anyone help?

Are you sending the email to the same email address on three occasions or is it three different emails to three different recipients?

Thanks for your reply & sorry for late response, I sent the 3 emails to the same email address
