I am currently using Yahoo! mail. Once I block someone, I don't receive an email from them. However, I want to send an automated reply to them as well to let them know that I have not received the email. For example, if the blocked email address sends me an email, an automatic response kicks in saying "Email not exist" or "The person didn't get your email" Or anything like that. How do I do this in Yahoo! mail?
Also, I can't just set an auto-response because I actually don't want to receive any email from them either.
