In both cases the lookup is by sender email address, not SASL login. And that is the documented behavior. There is a different appoach, and that is to use the "filter" feature. /etc/postfix/main.cf: ... check_sasl_access /etc/postfix/sasl_access ... /etc/postfix/sasl_access user1: filter relay1: user2: filter relay2: This usage is officially supported for remote deliveries.
