I think I still don't have a understanding at how to properly read / understand message headers in order to create good filters in Postfix. I am very sorry for my confusion but can someone please tell me what the difference is between these two IP's I show in the headers. I am guessing one IP is the actual 'senders' IP address in which is initiating SMTP from using a client like Outlook / Thunderbird and the other IP I am guessing is the address of the senders SMTP server which establishes a connection with my Postfix MTA, right? Do I at least have this correct? I am looking at these headers: ******************************************************************************* Return-path: <b.148.1296207.0e628e696f0d1...@mail.wfmc.org> X-original-to: car...@iamghost.com Delivered-to: car...@iamghost.com Received: from localhost (localhost.localdomain [127.0.0.1]) by mail.iamghost.com (Postfix) with ESMTP id 8A54C77A8E9 for <car...@iamghost.com>; Fri, 22 Jan 2010 05:29:33 -0500 (EST) Received: from mail.iamghost.com ([127.0.0.1]) by localhost (iamghost.com [127.0.0.1]) (amavisd-new, port 10024) with LMTP id eY2CHd1Jva+X for <car...@iamghost.com>; Fri, 22 Jan 2010 05:29:31 -0500 (EST) Received: from civismtp.uas.coop (civismtp.uas.coop [67.212.170.242]) by mail.iamghost.com (Postfix) with ESMTP id C00DB77A862 for <car...@iamghost.com>; Fri, 22 Jan 2010 05:29:30 -0500 (EST) Received: from wfmc.org (HELO www.wfmc.org) (192.220.23.216) (smtp-auth username editor, mechanism cram-md5) by civismtp.uas.coop (qpsmtpd/0.40) with ESMTPA; Fri, 22 Jan 2010 03:50:52 -0600 Mime-version: 1.0 Reply-to: r.148.1296207.0e628e696f0d1...@mail.wfmc.org From: "BPM Times" <edi...@bpm.com> Subject: BPM Times January 2010 List-unsubscribe: "" <mailto:u.148.1296207.0e628e696f0d1...@mail.wfmc.org> To: "car...@iamghost.com" <car...@iamghost.com> Content-type: multipart/alternative; boundary="=_6f6883e747bd1842f9d8a495eff04b03" Date: 01/22/2010 05:29:29 AM Message-id: <20100122095052.183d3192c...@civismtp.uas.coop> ******************************************************************************* There are two (2) 'Received: from' lines which both have two completely different IP's.
