Hallo liebe Community,
derzeit versuche ich mein Monitoringsystem mit meinem Exchangeserver zu verbinden.
Mein Plan ist die vom Monitoringsystem erstellen Mails über Postfix direkt an den Exchangeserver weiterzuleiten.
Hierfür habe ich auf dem Exchangeserver eine E-Mailadresse eingerichtet und mit einem bestehenden AD-User verknüpft.
Das Exchange-Konto funktioniert über die OWA ohne Probleme.
Leider scheint es mit der SASL Authentification Probleme zu geben (siehe Fehlermeldung).
Könnte mir jemand einen Tipp geben wo ich einen Fehler gemacht habe?
