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.
