Excuse me?!
Maybe the fact that everyone can claim to be anyone in SMTP might get

Authentication won't "solve" spam, but not having it sure makes
spamming easier and more annoying. (Today I even got a message claiming
to be from the email administrator for my domain. Guess who is the
email administrator of my domain... This type of forgery is also hard
on the spam filtering AI, usually resulting in a false negative.)
