Look up information regarding the sendmail access list
Should be able to use entries like this

cyberspammer.com 550 We do not accept mail from spammers
FREE.STEALTH.MAILER@ 550 We do not accept mail from spammers
another.source.of.spam REJECT


You'll need to compile it into the access.db after with a command similar to

makemap hash /etc/mail/access < /etc/mail/access
