Using sendmail -- which I realize isn't as fashionable these days as 
Postfix et al. -- SpamAssassin can be run as a milter. Its tests are 
run during the SMTP transaction and spam can be rejected with an SMTP 
550 message. The sending MTA, not the sending user, is notified of the 
rejection.

Assuming the MTA is legit, and not merely a zombie bot, the right 
person will be told that the message wasn't delivered because it looks 
and smells like spam.

If the MTA is actually a bot, it might decide to try again, or it 
might just continue on its merry (?) way like a telemarketer after a 
hang-up.
