Don't use MailScanner for RBL checks then. Either:

a) Block using RBL's at MTA stage so the sender gets a bounce notifiction
(From their own server)

b) Change the high score Spam settings to just tag and then deliver or
quarantine high scoring spam and put in MailWatch to release legitimate
for the quarantine.

Sending rejection messages is NOT the answer to this and will more than
likely get your client added to an black list themselves.
