I honestly can't be tossed to bother with the guy and raising an issue for it. His people skills tend to evoke the worst in me and I really can't be bothered with it. It is easy enough to reproduce. Just build a header filter like this; (put aside the fact this is going to catch a shed load of legit mail) /^Received: from.*(cmodem|dhcp|adsl|broadband|dynamic)/ REJECT dynamic host in headers This mail; Subject: UCE: 86.140.171.207 From: <munged> Reply-To: zen158...@zen.co.uk To: ab...@btbroadband.com Content-Type: text/plain Organization: <munged> Message-Id: <1244801375.6998.30> Mime-Version: 1.0 X-Mailer: Evolution 2.24.3 Content-Transfer-Encoding: 7bit Date: Fri, 12 Jun 2009 11:09:36 +0100 X-Evolution-Format: text/plain X-Evolution-Account: 1242054711.26374.4 Log excerpt below: un 11 20:17:35 mail4 postfix/smtpd[27674]: NOQUEUE: reject: RCPT from host86-140-171-207.range86-140.btcentralplus.com[86.140.171.207]: 554 5.7.1 Service unavailable; Client host [86.140.171.207] blocked using zen.spamhaus.org; http://www.spamhaus.org/query/bl?ip=86.140.171.207; from=<i...@totalbrides.co.uk> to=<munged> proto=ESMTP helo=<WORKLAPTOP-PC> In the logs; tripped on the header filter; Jun 12 11:01:58 mail4 postfix/cleanup[1419]: B9F16AC09D: reject: header Received: from [192.168.1.xx] (xx [192.168.1.xx])??by mail4.xx.co.uk (xx) with ESMTPA id B9F16AC09D??for <ab...@btbroadband.com>; Fri, 12 Jun 2009 11:01:58 +0100 (BST) from mail4[192.168.1.xx]; from=<mung...@munged.co.uk> to=<ab...@btbroadband.com> proto=ESMTP helo=<[192.168.1.xx]>: 5.7.1 dynamic host in headers But like you say - it's my misconfiguration....
