KES 9.6.96 protection against spoofing, how does it exactly work?

[ak01]

I found the announcement of the new feature “There is now protection against spoofing (faking the sender address for the purpose of concealing the actual author of an email message).” https://support.kaspersky.com/KS4Exchange/9.6/en-US/100302.htm

 

How does it exactly work? How does it recognize spoofed addresses? When it found a spoofed address, does it change the spam score (how does it look like for the user)? I have not found any additional explanation of that feature. Do I have to turn it on or is it turned on by default (where do I find the corresponding settings)?
