Hi, when an RBL is added, the permit_sasl_authenticated instruction looks like this in main.conf: Code: smtpd_client_restrictions = check_client_access proxy:mysql:/etc/postfix/mysql-virtual_client.cf, permit_inet_interfaces, permit_mynetworks, reject_rbl_client zen.spamhaus.org, permit_sasl_authenticated, ......... and has to be changed to Code: smtpd_client_restrictions = check_client_access proxy:mysql:/etc/postfix/mysql-virtual_client.cf, permit_inet_interfaces, permit_mynetworks, permit_sasl_authenticated, reject_rbl_client zen.spamhaus.org, ..... This is so? or could it be due to having modified the file manually before? Regards, Fermin
