If RBL are also used in smtpd_client_restrictions, helo check are done after RBL check.
I think it would be better to have the opposite, helo check first and then RBL check.

To have helo check before RBL I moved the helo check in smtpd_client_restrictions

smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated,
                             reject_invalid_hostname, reject_non_fqdn_hostname,
                             reject_rbl_client bl.spamcop.net,
