Oh yes........... I was expecting connexion to be immediately closed. In fact : By default, this restriction is applied when the client sends the RCPT TO command. In order to have the restriction take effect as soon as possible, specify smtpd_delay_reject = no in the Postfix main.cf configuration file. Doing so may cause unexpected results with poorly implemented client software. At least I can confirm that my solution is working for everyone that needs it :-) Thank you very much for your reply !
