Postfix restrictions work on input, not output. If you don't want to deliver mail somewhere, don't accept the mail when it arrives. Use smtpd_recipient_restrictions with check_recipient_access and/or check_recipient_mx_access maps to reject the unwanted mail. Note: smtpd restrictions are for mail submitted via SMTP, and are not intended for mail submitted via the sendmail(1) command. -- Noel Jones
