At least as long as you do not invent an AI routine which can distinguish between legitimate users and clever SPAMmers ;) Of course you can enhance Sendmail with a milter application like MimeDefang which has then Perl program code which suppresses DSN notify mails when it thinks to recognize SPAM attempts. Anti-SPAM fighting is a never ending story, you as mailserver admin are ever followed by the flexible SPAM troupers, The easiest way is to observe the maillog and based on this logging to run a cronjob which blocks the SPAMmers by iptables rules. I can send you a working script for that if you like.
