the email to the invalid recipient goes from the email-client to
postfix, then to the relay-server, the relay-server bounce the email because of the invalid
(non existent) recipient, postfix then generates an email for the
sender of this email but cannot send this information to the
relayserver because the x-envelope-from field is empty( it is bounced by the relay-server).

the client generates a valid header.
