I expect your locally-generated mail goes through the sendmail(1) interface, rather than SMTP. Mail submitted to sendmail(1) enters the postfix qaueue by the pickup(8) service in master.cf. It's not uncommon to set an empty "-o content_filter=" on the master.cf pickup service to disable filtering on locally-generated mail. http://www.postfix.org/OVERVIEW.html http://www.postfix.org/sendmail.1.html http://www.postfix.org/pickup.8.html -- Noel Jones
