1399319851 670x281

Sometimes you accidentally give out your personal email address to an unfortunately persistent contact, or you want to stop seeing emails from a frenemy. Marking their messages as spam isn’t enough, since you don’t want to depend on spam filters to keep them out of your inbox. In Yahoo Mail, you can block up to 500 addresses from sending you messages. Here’s how to make sure you never get email from someone again.  

1. Sign in to your Yahoo Mail account.

Once you’ve added a contact to your blocked list, you won’t receive any more messages from that address. You can always unblock a person by selecting their name from the list and clicking Remove at the right.

    thank you for your tutorial; i was looking, however, for the way to block an entire domain in Yahoo. I’ve tried the and formats, but get an error that the first style is an invalid address, and I still get emails from the domain in the 2nd style. Any ideas on how to fix?
