Hallo

Ich habe Postfix installiert. Nun erhalte ich beim Empfang von E-Mails folgende Fehlermeldung:

May 21 14:12:01 hostname postfix/smtpd[5204]: warning: 115.XXX.XXX.XXX.list.dsbl.org: RBL lookup error: Host or domain name not found. Name service error for name=115.XXX.XXX.XXX.list.dsbl.org type=A: Host not found, try again

May 21 14:12:02 hostname postfix/smtpd[5204]: disconnect from nm20-vm0.bullet.mail.ukl.yahoo.com[217.146.183.115]

Die Mails werden nicht zugestellt.

Mails verschicken kann ich ohne Probleme.

Ich habe gegoogelt und hier im Forum gesucht, aber ich werde irgendwie nicht schlau. Vielleicht hat das auch was mit dem Paket "Spamassassin" zu tun?

Bin um jede Hilfe dankbar.

Danke und Gruss Marco

EDIT: Ich habe nun die Pakete "python-policyd-spf python-spf" entfernt und in /etc/postfix/main.cf und /etc/postfix/master.cf gewisse Einträge dazu entfernt und nun erhalte ich Mails.

Meine Frage dazu aber: wäre es mit SPF nicht ein bisschen sicherer? Und falls ja, wie kriege ich das hin?

Zeig doch mal die Konfiguration von Postfix (main.cf, master.cf) . Sieht so aus als wäre SPF nur falsch konfiguriert gewesen, so dass Postfix das nicht findet.

Hallo nbkr

Danke für Deine Hilfe.

Unten die beiden Auszüge von main.cf und master.cf. Ich habe die SPF relevanten Dinge wieder auskommentiert, da ich gerade Open-XChange am installieren bin und darum eine funktionstüchtige Umgebung brauche.

Zu Deiner Info noch: ich hatte den Wert "check_policy_service unix:private/policy-spf" auch mit dem absoluten Pfad (über /var/spool/...) ausprobiert, hat aber nicht funktioniert.

main.cf

Also in meiner master.cf steht dass drin:

policy-spf   unix   -   n   n   -   -   spawn
     user=nobody argv=/usr/bin/policyd-spf

In der main.cf

check_policy_service unix:private/policy-spf

Damit funktioniert es, ist auch ein Ubuntu 10.04.

Hallo nbkr

Besten Dank für Deine Hilfe!

Ja, so hatte ich das auch eingestellt und auch nach ein paar Stunden mit Google habe ich nichts dazu gefunden. Da stimmt sonst was nicht.

Ich lasse es mal ohne SPF, danke aber nochmals recht herzlich.

Gruss Marco
