[Postfixbuch-users] Probleme mit "Considered UNSOLICITED BULK EMAIL"

[Martin MŸüller | Rudolf Hausstein OHG]

Hallo!


Ich hab hier ein Problem mit

amavisd-new 2.4.2-6.1
postfix 2.3.8-2+etch1
spamassassin 3.2.3-0.volatile1


Wenn ich von der office-adresse eine eMail versenden will, bekomme ich 
folgende Mail zurück:

-------------------
A message from <office at MeineDom.at> to:
-> office at hausstein.at

was considered unsolicited bulk e-mail (UBE).

Our internal reference code for your message is 01542-01/TX9JEwSH69xG

The message carried your return address, so it was either a genuine mail
from you, or a sender address was faked and your e-mail address abused
by third party, in which case we apologize for undesired notification.

We do try to minimize backscatter for more prominent cases of UBE and
for infected mail, but for less obvious cases of UBE some balance
between losing genuine mail and sending undesired backscatter is sought,
and there can be some collateral damage on both sides.

First upstream SMTP client IP address: [192.168.100.40] unknown
According to a 'Received:' trace, the message originated at: 
[192.168.100.40],
  [192.168.100.40] (unknown [192.168.100.40])

Return-Path: <office at MeineDom.at>
Message-ID: <4BA32A90.6030404 at MeineDom.at>
Subject: test

Delivery of the email was stopped!
----------------------

Im mail.info-log steht dann:

Mar 19 08:29:05 mail amavis[2803]: (02803-01) Blocked SPAM, LOCAL 
[192.168.100.40] [192.168.100.40] <office at MeineDom.at> -> 
<office at EineTestdomaind.at>, quarantine: spam-jbWvf7AyZr0k.gz, 
Message-ID: <4BA332B1.50205 at MeineDom.at>, mail_id: jbWvf7AyZr0k, Hits: 
6.604, 7041 ms



Wenn ich vom selben Mailclient statt der Office-Adresse eine 
persönliche-Adresse versende, klappt alles ganz normal.


Was könnte es hier aufsich haben? Vielen Dank für eure Antworten!


LG, Martin
