Hallo zusammen,
ich stelle seit ein paar Stunden ein seltsames Verhalten fest. Es wird augenscheinlich ein greylisting für neue Adressen durchgeführt, was bei im AD existierenden Usern wunderbar funktioniert. Bei quatsch-Adressen kommt es sofort nach dem greylisting Eintrag im Log auch noch zusätzlich zum verify und anschließed 550 vom Exchange 2010. Die Zustellung usw. funktioniert wunderbar, nur wundert mich das Verhalten doch sehr, weil es bis vor kurzem noch anders war. Da wurde "richtig" ge-greylisted, heisst, greylisting weist die quatsch-mail mit 450 ab und das wars. Evtl. ists auch nur ein Verständisproblem meinerseits, bin Anfänger :-). Hier mal ein Auszug aus dem Log, bei dem es nicht funktioniert:
