You are entitled to your opinion of course.

If you are certain it is spam, reject it before you accept it. If you have 
accepted it, the file it somewhere where the recipient has a chance to get to 
it.

How do you figure that? You deliver the message if it passes your border 
checks. If you think it’s spam after that, you can deliver it to the 
recipient’s spam folders where they are free to ignore it. You do NOT throw it 
away.

When your mailserver says “OK, I’ve received the message and am closing the 
transaction”, you’ve accepted it.

How does that follow? Don’t discard the message and there’s no problem.
