Outlook and spam message

I'm become on only one domain this message when I send a mail from outlook express

Code:

wurde als unerwünschte Massen-Mail (SPAM) klassifiziert.
Subject: MIETVERTRAG
Return-Path: <test@example>

Die Auslieferung der Nachricht wurde gestoppt!

 

You should contact the administrator of the receiving domain and ask why this happens.

 

Its a domain is Hosting by me on my server. I don't understand the other domains have any problem I can send to everywhere. Only this domain.

 

I think the problem is amavis . Have any person a link for the new amavisd configuration or howto

 

I have the mailfilter in amvisd for uncomment and than it work. The Problem is amavisd. I have see falco have the howto for amavisd change and I search for
problems with old and new version. I have any change find .

 

Code:

#@bypass_spam_checks_maps = (
 #  \%bypass_spam_checks, \@bypass_spam_checks_acl, \$bypass_spam_checks_re);

I have see on all domains is the Problem and my questions is this right in the
conf here ?

Code:

 cat 05-domain_id
use strict;

# $mydomain is used just for convenience in the config files and it is not
# used internally by amavisd-new except in the default X_HEADER_LINE (which
# Debian overrides by default anyway).

#chomp($mydomain = `head -n 1 /etc/mailname`);

# amavisd-new needs to know which email domains are to be considered local
# to the administrative domain.  Only emails to "local" domains are subject
# to certain functionality, such as the addition of spam tags.
#
# Default local domains to $mydomain and all subdomains.  Remember to
# override or redefine this if $mydomain is changed later in the config
# sequence.

@local_domains_acl = ( ".$mydomain" );
