I think you need to take a serious look at LDAP mail routing in Sendmail. I recently setup LDap routing on a businesses front end MX mail servers (Sendmail) and their rejected bounces went from 3000 a day down to 5. With LDAP mail routing all mail is rejected at the MX server unless it's for a legitimate user and the best part is once you have LDAP configured it's trivial to maintain. Oh! and LDAP is case insensitive. John
