How do you block incoming mail?

How can I block an incoming E-mail address?

• I use Yahoo-Mail for my e-mail, and want to block someone from contacting me by using my e-mail.

• Answer:

  You can block an address and Yahoo will delete any emails arriving from that address immediately----and you'll never see any of them. That email will NOT be returned to the sender (Yahoo deletes it), and they are not notified that they have been blocked (for security reasons). They will think you're still getting their emails and are just ignoring them. Mail page>>options>>mail options>>Spam (from the list on the left)>>block addresses. Enter that exact address in the space provided>>click "add block">>THEN click "save changes" at the top of the page. ......................................… HOWEVER If you're referring to Spam----trying to block Spam is a colossal waste of time, ----(it's mostly ineffective). Spammers change their addresses with "each" batch they send out and never reuse one, so they slip easily past blocks. Just click the Spam tab on them and let Yahoo deal with them, which they do by sending them to the Spam folder (instead of the inbox) and deleting them at preset times.
