Hello, If i understand, the smtpd_recipient_restrictions allow just to give postfix the list of addresses for wich he can accept emails, but my need is to prevent that an other person use an other mail server to send emails using our domain. It mean i want to specify to postfix the servers that can send mails using mydomain, and NO OTHER SERVER can do it. If postfix receive emails relayed by other server and coming from mydomain Sender with @mydomain address, it must reject that email.
Your understanding is wrong. Read up on smtpd_recipient_restrictions and check_sender_access. Use a config something like: smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination check_sender_access hash:/etc/postfix/sender_access # contents of /etc/postfix/sender_access example.com REJECT only internal mail allowed replace example.com with your own domain. -- Noel Jones
