[postfix-users] Client host rejected: cannot find your hostname

[Gerhard Waldemair]

Hallo,

ich brauch mal eure Hilfe:

Mir schicken 2 Kunden eine eMail. Ich kenne die eMail Adressen und würde die Mail gerne annehmen. Aber Postfix macht mir einen Strich durch die Rechnung.


Hier das Log:

Dec 27 10:12:07 mail postfix/smtpd[17239]: warning: 217.114.212.50: hostname ns.km22634.keymachine.de verification failed: Name or service not known

hier die andere:

Wie komme ich an die Mails ?

ich habe es bereits mit einer Whitelist probiert:

dazu habe ich eine Datei erstellt mit diesem Inhalt:

mail:/etc/postfix# cat whitelist
62.146.124.127	 OK
62.146.124.175	 OK
ns.km22634.keymachine.de	OK

und die Whitelist in der main.conf  

smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_client_access hash:/etc/postfix/whitelist, reject_unauth_destination, reject_unauth_pipelining, reject_non_fqdn_recipient, reject_invalid_hostname, check_policy_service inet:127.0.0.1:60000, permit

eingefügt, aber leider ohne Erfolg. Hat wer einen Tip für mich ?

Danke Gerhard.
