seit heute habe ich mit meinem Rootserver keinen Mailempfang mehr. Ein Blick in die Logs zeigt:

Ein offenes Relay liegt nicht vor, wie mir ein Test bei Abuse.net zeigt.
Der Postfix lief sonst immer problemlos durch.

Wie bekomme ich den Mailempfang wieder hin?
Und warum gelingt es mir nicht, die Verbindung zu *.rr.com zu unterbinden?
Vielen herzlichen Dank für Eure Hilfe
