If you're seeing emails from specific senders that you'd rather not see, Yahoo! provides a way to block them easily and never see another message from those senders again. In fact, Yahoo! Mail can block all mail from as many as 500 email addresses. All mail from these senders will be deleted automatically before you even see it.

Blocking Unwelcome Senders Is Not Blocking Junk Emails

Don't let the large number of blockable addresses lure you into thinking you can fight spam with this method, though. Spammers can and often do use a fresh address (or domain name) for every junk email they send.

Instead, use the list of blocked senders for individual senders whose messages you do not want to receive but cannot stop easily. Instead of having to delete every new mail from each of these addresses by hand, Yahoo! Mail can do the cleaning for you.
