Did you know that if a spammer uses your email address as the FROM: address, which is easy to do, all the bounce messages will go to your email address? If the spammer really hates you, they will send millions of emails with your FROM: address and you will get a million bounce messages.
Can you stop this or prevent this? No
Why would a mail provider send you a bounce message, knowing you’re innocent? Because that’s how someone wrote the protocol back then, and nobody changes it or does it differently because … reasons.
Does the spammer get a bounce message? Nope, not one.
Does the SMTP sending account owner whose credentials were stolen be notified about bounces so they can stop the spam? Nope.
Just millions of emails sent every day to poor schlameels who have no idea why they are getting them and who can’t do anything about them.
The more I learn about the email protocols, the more I realize how terrible the design is.

You keep saying we don’t read or we don’t understand, but as an email admin at a large company, let me tell you that actually you are wrong.
The sending server doesn’t even know whether the spam mail was delivered or dropped by the receiving end.
It only knows in case the mail was rejected.
