Hi, I tried to adopt smtp dsn like dokumented here: http://www.postfix.org/postconf.5.html#default_delivery_status_filter
Since the example is exactly what I want (so my users get Non delivery notifications for domains where we refuse to send without transport encryption but won't offer it earlier) I just c&p'd. However - it does not seem to do anything. Any mail sent to such a destination still gets a 4.. status. Any help debugging whats going on would be appreciated. /r -- Rainer Ruprechtsberger Volkshilfe Oberösterreich IT 4020 Linz, Glimpfingerstrasse 48 Tel.: +43 732 3405 123 Mobil.: +43 676 8734 1123 ZVR Zahl: 064371505 Volkshilfe.
