Note: you are search for *outbound* mail controls. > - smtpd_client_connection_rate_limit > - smtpd_client_message_rate_limit > - smtpd_client_recipient_rate_limit The above are for *inbound* mail. Do not confuse *outbound* mail with *inbound* mail. > - transport_destination_concurrency_limit > - /etc/postfix/transport > domain.com slow: That controls *concurrency*. Do not confuse outbound *rate* control with *concurrency* control. For *outbound *rate* control see http://www,postfix.org/postconf.5.html#transport_destination_rate_delay To apply, replace "transport" with the name of the mail delivery transport (e.g., slow_destination_rate_delay, when sending mail via the "slow" transport map entry).
