Would such a policy force Postfix to *close* that particular socket? I don't want to force a retry at the client side, I want to force the client to stop reusing the connection and open a new one from time to time. Ideally after a max number of messages, if not possible after a TTL for the connection between the SMTP client and Postfix. I found this other parameter in the documentation: http://www.postfix.org/postconf.5.html#smtpd_policy_service_max_ttl My understanding is that this TTL refers to the connection between smtpd and the policy server, not between smtpd and the SMTP client. Thank you, Diego
