The senders address could be faked. But what do they want from you. Is there a link in the email asking you to visit a webpage?
Why not logging into your binance account to see if there is as well a message. But don't klick on links in emails, please.
First, don't click the email sent to you. Better log in directly to your binance account.
Once you access your account, check the notifications sent to you.
Because if there is no notif regarding the sms authentication, then, the email is fake.
Maybe someone is trying to change the mobile number attached to your account.
And I don't think directmail2.binance.com comes from official binance account.
