[postfix-users] kein Relaying denied

[Richard Gliebe]

Hallo zusammen,

ich bin gerade dabei auf Postfix (postfix 2.5.1-2ubuntu1.2) das 
"Relaying Denied" scharf zu machen, sprich nur Emails aus unserer Domain
(user@<our_domain>.at) dürfen versendet werden, ansonsten: relaying denied.

Ich habe daher folgende Parameter ins main.cf eingetragen:

...
# grep -i relay main.cf

relay_recipient_maps = hash:/etc/postfix/relay_recipients
relay_domains = hash:/etc/postfix/relay_domains
smtpd_recipient_restrictions = permit_mynetworks
reject_unauth_destination reject_unauth_pipelining check_relay_domains
...

Hier noch die PlainText Files:

# cat /etc/postfix/relay_recipients
@<our_domain>.at OK

# cat /etc/postfix/relay_domains
<our_domain>.at	OK

Wenn ich das ganze Zeugs jetzt mit einer telnet Session auf Port 25
teste, klappts irgendwie nicht so recht ...

administrators-macbook-3:~ glr$ telnet postman 25

Vielleicht sieht jemand ja den richtigen Baum in diesem ganzen Wald oder
fehlt mir da noch ein Setzling?

Danke
