Hi,
I may be barking up the wrong tree. But since the following email only had a single IP v4 hop to our Imail, I can't see how this could possibly be caught by "spamrouting" - unless there is some confusion on how to treat the IP v6 address address: Received: from SDKENG01.dkeng.co.uk [81.143.158.102] by hm-software.com with ESMTP (SMTPD-11.02) id 3f5e0001d39c4dd5; Fri, 8 Oct 2010 04:44:53 -0400 Received: from SDKENG01.dkeng.co.uk ([::1]) by SDKENG01.dkeng.co.uk ([::1]) with mapi; Fri, 8 Oct 2010 09:43:21 +0100 . X-RBL-Warning: This E-mail was routed in a poor manner consistent with spam [2000011f]. See: http://tools.declude.com/headercode.php?code=2000011f X-Declude: Version 4.10.51; Code 0x2000011f from host81-143-158-102.in-addr.btopenworld.com [81.143.158.102] The only other server uses the standard IP v6 loopback address (0:0:0:0:0:0:0:1), equivalent to the 127.0.0.1 in IP v4 - which clearly is internal and thus should not be evaluated for the Spamrouting test. If Spamrouting (or Declude?) does not handle IP v6, then it probably should at least SKIP those headers entirely?
