[Postfixbuch-users] config Fehler

[Klaus Schuehler]

Hallo,

seit ein paar Tagen erhalten ich einen Eintrag in den
Logfiles mit dem ich wenig anfangen kann.

Mar  9 18:02:32 tirol postfix/smtpd[23842]: warning: 
227.192.72.217.dynablock.njabl.org: RBL lookup error: Host or domain name not 
found. Name service error for name=227.192.72.217.dynablock.njabl.org type=A: 
Host not found, try again

Dieser Eintrag kommt Zuhaufe.
Habe meine Konfiguration mehrfach überprüft und finde den Fehler nicht.

 See /usr/share/postfix/main.cf.dist for a commented, more complete version
