Zitat von Pol Hallen <postfi...@fuckaround.org>:
Follow official postfix page (http://www.postfix.org/DSN_README.html) I've: smtpd_discard_ehlo_keyword_address_maps = cidr:/etc/postfix/esmtp_access cat /etc/postfix/esmtp_access # Allow DSN requests from local subnet only 192.168.1.0/24 silent-discard 0.0.0.0/0 silent-discard, dsn ::/0 silent-discard, dsn I've small lan on 192.168.1.0 and all clients uses a single smtp postfix server. On clients, send the emails with "delivery status notification" option. After sent, postfix send me a delivery status notification: Successful Mail Delivery Report but that email is within postfix queue (why I stopped destination over internet smtp server - purpose test). So, my postfix server always send a delivery status notification also if there's a transmission problem. What's the error?
Do you have a AV scanner or some other after queue content filter? If yes postfix is maybe telling you that the message has been transfered to this next hop. IMHO you should ditch DSN because no one is using/allowing it anyway, so trying to get it right is a fruitless effort.
