How do i block someone from sending me e-mails on yahoo?

How do I block someone from sending me emails to my yahoo mailbox,?

• Iwas told click on options and choose block but that is not under my options whenever I check my email, the content of these emails are filthy and slanderous from someone I know

• Answer:

  Block them this way. Mail page>>options>>mail options>>Spam (from the list on the left)>>block addresses. Enter the exact address you want to block>>click "add block">>then click "save changes" at the top of the page. Any future emails from that address will be deleted as soon as it arrives at your account----you'll never see any of them. The sender is NOT notified that they have been blocked----and will think you are still getting their emails.
