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.
