This is a passage usually attached to the end of foreign business emails. It's a legal cliche, and many foreign companies will automatically attach this passage to their emails. Just to tell you, if this email is not addressed to you, you should not copy and spread it. Because e-mail is often sent to the wrong person. As for if it is not for you, please reply to him, that is, let me know and delete it. He sent it wrong, which means it has nothing to do with you legally.

As for not watching, that's bullshit. You said, how do you know it's not for me if I don't look at it?
