Is it possible to reject e-mail sent to me from a specific address?

If you have e-mail service with us, you can reject incoming mail from certain senders. See the “Manual whitelisting and blacklisting” section of this page for more details.

In addition, most e-mail programs (including Outlook, Thunderbird, and Apple Mail) allow you to set up rules or filters to automatically delete messages sent from a specific e-mail address.
