RESOLVED_IP_IS_NOT_HELO

[Helga Mayer]

Hello,

Oct 14 10:56:35 smtp2 postfix/policyd-weight[27531]: weighted check: 
NOT_IN_SBL_XBL_SPAMHAUS=-1.5 NOT_IN_SPAMCOP=-1.5 NOT_IN_BL_NJABL=-1.5 
CL_IP_NE_HELO=1.5 RESOLVED_IP_IS_NOT_HELO=1.5 (check from: .ivlv. - helo: 
.h6524.serverkompetenz. - helo-domain: .serverkompetenz.) 
FROM_NOT_FAILED_HELO(DOMAIN)=3; <client=85.214.67.12> 
<helo=h6524.serverkompetenz.net> <from=$SENDER at ivlv.org> 
<to=$RECIPIENT at uni-hohenheim.de>; rate: 1.5

the above mentioned mail was rejected.
The sender domain matches the helo.
ivlv.org has address 81.169.178.183
h6524.serverkompetenz.net has address 81.169.178.183
Both of course can be forged.

I asked the administrator to 
adjust his settings (HELO according to IP) and got the following answer:

Es handelt sich bei diesem Vorgang um kein gefälschtes Hello oder einen
ähnlichen Vorgang. Der von Ihnen beschriebene Vorgang entsprechend einer
Nutzungsmöglichkeit, die wir unseren Kunden anbieten; die Nutzung von 2
IP-Adressen mit einem Server.

(sorry for posting the original text without translation)

In fact there are 2 addresses which accept mail:
81.169.178.183
and
85.214.67.12 
The common helo ist h6524.serverkompetenz.net (81.169.178.183)
But there is only one outgoing server: 85.214.67.12

Is there any RFC saying the helo should match the ip ?
