cat /opt/etc/postfix/transport | grep -v "#" postfix.org smtp:[smtp.mysip.ch]:587 domain.tld smtp:[smtp.myotherisp.ch]:587 And only once in the config (main.cf transport_maps...). I can see the unauthorized relay attempts with myisp.ch/myotherisp.ch in the Postfix logs. So I assume that no login credentials were used. Is transport meant to use the data from sender_relay and sasl_passwd files to login to the relay servers? Regards tobi
