When you receive emails with malicious content, you can choose to block and reject emails from that sender. This will move the current email to the Spam folder and bounce all future emails from the sender back to them.

To block and reject future emails:

1. Open the email from the sender that you wish to block and reject.

2. Click the More Options icon in the email detail view.

3. Select Block and Reject Future Emails.

4. Click Block.
