How do I delete some email addresses from my contacts list?

Can I deny non-contacts access to my email address?

• People who advertise products I do not want are literally bombarding me with emails. They cannot be blocked because they change their senders details with every email they send and appear to delete their details immediately after they have send an email to thousands of other people whose email addresses they have acquired by illegal means. If Yahoo does not have the facility I want, is there a case for asking Yahoo to develop a system where only those on the contacts list have access to one's email address?

• Answer:

  1. Click on the "Options" link in the upper right of your yahoo mail page. 2. Click on "Spam Protection", fill out the form and click the "Save Changes" link. Once you have this set up, each time you see spam or mail that you want to block, check the box next to it, go to the top of the email list and click the "Spam" button. Note: Every message you report trains your Spam Guard filters to work better for you. The messages you select in this way will be deleted and reported as spam. The senders of the messages will be added to your "Blocked Addresses" list.
