Hi,
Here I attached a video to show you how to block specific email address from coming into the mailbox in yahoo mail.

P/S : This instruction video was created for 1 of my friend, but she did not appreciate my effort, because she think that I can just magically block one of the person from her email. Unless I am one of the yahoo mail admin, but even if admin, it would violate the rules.
