      How do I block mail from a specific sender?

      Blocked Addresses are email addresses from which you do not want to receive any mail. All incoming mail from these addresses will be automatically deleted without bouncing back to the sender. You may also block mail sent from an entire domain. AT&T Yahoo Business Email allows you to block up to 500 email addresses or domains. When you remove an address or domain from your Blocked Addresses list, you will once again be able to receive mail from that address.

      If you receive a message from a sender and want to block that sender:

      1. From your inbox, check the box next to the message.
      2. Click the "Spam" button at the top of the page.
      3. The message will be marked as spam, and the sender's email address will be added to your Blocked Addresses list.

      If this option is not working, please ensure that you have enabled this feature in your Spam Protection settings. To check the settings, click on "Mail Options" and then on "Spam Protection." On the Spam Protection page, please make sure "Add the sender's email address to my blocked addresses list" is checked, then click on the "Save Changes" button.

      To manually add an address or domain to your list of blocked addresses:

      1. Click "Mail Options," located near the top-right corner of the main Mail page.
      2. Click the "Block Addresses" link.
      3. Type the address or domain you want to block in the "Enter email address (or domain) to block" field.
      4. Click on the "Block Address" button. The address will appear in your list of blocked addresses.

      To remove ("unblock") an address or domain:

      1. From the Blocked Addresses list, select the address you wish to remove from the list.
      2. Click the "Remove Block" button at the bottom of the list. You will once again be able to receive mail from that address.

      Please note that this feature is not available for users with POP-only mailboxes.
