spamassassin_psa dynamic IP and RBL`s

[OliverG]

I have the following problem with false positive spams.

I send a mail with a dynamic IP over STMP Port 25 to mailserver 1.
Mailserver 1 delivers the mail to the receipient on mailserver 2.
Mailserver 2 marks the mail als spam.

The Header-Code:
-----------------------------------------------------------------------------
Received: (qmail 13819 invoked from network); 18 Jan 2011 14:39:52 +0100
Received-SPF: none (no valid SPF record)
Received: from mailserver1.domain.tld (87.230.xx.xx)
by mailserver2.domain.tld with (DHE-RSA-AES256-SHA encrypted) SMTP; 18 Jan 2011 14:39:51 +0100
Received: (qmail 9777 invoked from network); 18 Jan 2011 14:39:51 +0100
Received: from tmo-104-162.customers.d1-online.com (HELO ?10.210.142.130?) (80.187.104.162)
by mailserver1.domain.tld with SMTP; 18 Jan 2011 14:39:51 +0100
-----------------------------------------------------------------------------

The spamassassin result:
-----------------------------------------------------------------------------
3.0 NIX_SPAM RBL: Listed in NIX_SPAM DNSBL (thanks to heise.de)
[80.187.104.162 listed in ix.dnsbl.manitu.net]
2.2 RCVD_IN_BL_SPAMCOP_NET RBL: Received via a relay in bl.spamcop.net
[Blocked - see <http://www.spamcop.net/bl.shtml?80.187.104.162>]
2.5 RCVD_IN_PSBL RBL: Sender is listed in PSBL
[80.187.104.162 listed in psbl.surriel.com]
-0.2 AWL AWL: From: address is in the auto white-list
-----------------------------------------------------------------------------

The mail is sent from the dynamic IP 80.187.104.162 and scanned by spamassassin.
How can I reach that only the last IP from the "received from headers" will be scanned?

Thanks

Olli

it simply - just edit spamassassin rule(s), usually it in /usr/share/spamassassin
