Note
If you want to add a sender to the Blocked Senders list and you don't have a message from that sender available, you can add the sender's address manually. To do this, click the Message menu, point to Junk e‑mail, and then click Junk e‑mail Options. Click the Blocked Senders tab, click Add, type the e‑mail address you'd like to block, and then click OK.
