Why does my mailbox receive an email from a foreigner I don't know and the recipient is another person?

1. Receiving unwanted mail is spam;

2. When you receive an email, it means that the other party knows, and you must have registered something online with this email;

3. It is normal to show that the recipient is not you. You can still receive it if the bcc has your address.
