[Postfixbuch-users] Remote host said: 503 5.7.4 Error: authentication disabled

[Burkhard Pauli]

Hallo,

ich habe ein Prblem mit einem bestimmten Mailserver, der keine Mails zu 
meinem Server schicken kann. Es kommt statt dessen folgende 
Fehlermeldung zurück:

---------------------------------------------

Hi. This is the qmail-send program at zit-mailfront1.uni-paderborn.de.
I'm afraid I wasn't able to deliver your message to the following 
addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
For problems contact postmaster at hrz.uni-paderborn.de, please.

<vertrieb at geurten-edv.de>:
81.169.176.173 does not like recipient.

-----------------------------------------
Mein System ist:
Postifix (2.1.5) + Amavisd-new (0.20040701)

Ich hab schon versucht folgende Einstellungen in meine amavisd.conf 
einzutragen:

auth_mech_avail = qw(PLAIN LOGIN);
$auth_required_inp = 0;
$auth_required_out = 0;

leider startet dann mein Amavis nich mehr. Vielleicht noch jemand eine 
Idee?
Danke
