Kein Mailempfang mehr auf Rootserver
Posted: 2007-03-17 22:54
Hallo Forum,
seit heute habe ich mit meinem Rootserver keinen Mailempfang mehr. Ein Blick in die Logs zeigt:
/var/log/mail
Nun war meine Vorstellung, daß die extrem vielen Einträge von rr.com den Mailempfang stören. Daher versuchte ich, mit iptables die betreffenden IPs zu sperren.
Nur führte das zu keinem Ergebnis.
Ein offenes Relay liegt nicht vor, wie mir ein Test bei Abuse.net zeigt.
Der Postfix lief sonst immer problemlos durch.
Die main.cf:
Nun meine zwei Fragen:
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
