Postfix will stop delivering after TCP or SMTP handshake failure. Postfix WILL NOT stop delivering due to 4xx reply AFTER the SMTP protocol handshake. Postfix is not a tool to work around receiver policy restrictions. If you want to send more than a few email messages, then it is your responsibility to make the necessary arrangements with receivers. Over and out. Wietse
