There are many ways to do this, such as setting your server up as relay and using a reject rule. The easiest way, however is to probably enter the user name in the /etc/mail/aliases file as an alias to /dev/null. All mail for the user will be discarded. Your entry in /etc/mail/aliases would be

user: /dev/null

Once you do this restart the sendmail process and you should be set.
