That line says that Yahoo checked your SPF when it received the mail from you and your lists.example.com SPF designated your IP as a permitted sender so it was OK. However, the message was then relayed by Yahoo to the recipient's MX and the recipient's MX checked the domain of the envelope sender (still lists.example.com) and it's SPF did not designate nm1.bullet.mail.sp2.yahoo.com which is the serve from which it received the mail as a permitted or at least neutral sender, so the recipients MX refused the mail. Your choices are: 1) don't publish SPF 2) don't relay via Yahoo 3) designate ?all in your domain's SPF (maybe others, I'm not an SPF expert) [...] >Also, I note: > >X-YahooFilteredBulk: 10.10.10.99 <-- what does "X-YahooFilteredBulk" mean? Ask Yahoo. It's their non-standard (private) header. >And there is another value for this field. >X-Originating-IP: [76.21.140.158] It appears that the mail originated at your "homecomputer3" via a comcast ip and was relayed via worldnet.att.net which noted that it originated from the comcast IP 76.21.140.158. Subsequently, it was delivered to l...@lists.example.com at some server variously reported as 'localhost', 127.0.0.1 (Generally the IP of 'localhost'), myhost.hostingprovider.com (aka the local network IP 10.10.10.99), and mta1017.biz.mail.mud.yahoo.com all of which appear to be tthe same actual machine, and subsequently it was relayed via another Yahoo server which checked the SPF for lists,example.com and found it designated 10.10.10.99 as a premitted sender. >These are the headers of the bounced message: > >Subject: Failure Notice >Sorry, we were unable to deliver your message to the following address. > ><recipi...@destination.com.br>: >Remote host said: 550 5.7.1 SPF MAIL FROM check failed: [MAIL_FROM] > >--- Below this line is a copy of the message. > >Received: from [72.30.22.79] by nm1.bullet.mail.sp2.yahoo.com with NNFMP; >09 May 2012 21:51:02 -0000 >Received: from [68.142.200.224] by tm13.bullet.mail.sp2.yahoo.com with >NNFMP; 09 May 2012 21:51:02 -0000 >Received: from [66.94.237.102] by t5.bullet.mud.yahoo.com with NNFMP; 09 >May 2012 21:51:01 -0000 >Received: from [127.0.0.1] by omp1007.access.mail.mud.yahoo.com with NNFMP; >09 May 2012 21:51:01 -0000 >X-Yahoo-Newman-Property: ymail-3 >X-Yahoo-Newman-Id: 502900.95307...@omp1007.access.mail.mud.yahoo.com >X-Yahoo-Forwarded: from recipi...@destination.com to >recipi...@destination.com.br >Return-Path: <all-boun...@lists.example.com> >X-YahooFilteredBulk: 10.10.10.99 >Received-SPF: pass (domain of lists.example.com designates 10.10.10.99 as >permitted sender) >X-YMailISG: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx >X-Originating-IP: [10.10.10.99] >Authentication-Results: mta1017.biz.mail.mud.yahoo.com from=3D >lists.example.com; domainkeys=3Dneutral (no sig); from=3Datt.net; >dkim=3Dpermerror (bad sig) >Received: from 127.0.0.1 (EHLO localhost) (10.10.10.99) > by mta1017.biz.mail.mud.yahoo.com with SMTP; Wed, 09 May 2012 14:51:01 >-0700 >Received: from myhost.hostingprovider.com (localhost [127.0.0.1]) > by localhost (Postfix) with ESMTP id E9CA1123AB; > Wed, 9 May 2012 21:43:23 +0000 (UTC) >X-Original-To: l...@lists.example.com >Delivered-To: l...@lists.example.com >Received: from fmailhost01.isp.att.net (fmailhost01.isp.att.net > [204.127.217.101]) by localhost (Postfix) with ESMTP id 1D84D123A4 > for <l...@lists.example.com>; Wed, 9 May 2012 20:52:06 +0000 (UTC) >DKIM-Signature: v=3D1; q=3Ddns/txt; d=3Datt.net; s=3Ddkim01; i=3Dmember1@do= >main.net; > a=3Drsa-sha256; c=3Drelaxed/relaxed; t=3D1336596725; h=3DContent-Type: > MIME-Version:Message-ID:Date:Subject:In-Reply-To:References:To: > From; yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy >Received: from homecomputer3 > (c-76-21-140-158.hsd1.va.comcast.net[76.21.140.158]) > by worldnet.att.net (frfwmhc01) with SMTP > id <20120509205204H0100sdv2pe>; Wed, 9 May 2012 20:52:05 +0000 >X-Originating-IP: [76.21.140.158] >From: "Member One" <memb...@domain.net> >To: "'Example Discussion'" <l...@lists.example.com> >References: < >13283191.1336591910177.javamail.r...@wamui-june.atl.sa.earthlink.net> >In-Reply-To: < >13283191.1336591910177.javamail.r...@wamui-june.atl.sa.earthlink.net> >Date: Wed, 9 May 2012 16:52:07 -0400 >Message-ID: <!&!aaaaaaaaaaaaaaaaaaaaaaaaaaaaa=3D=3...@att.net> >MIME-Version: 1.0 >X-Mailer: Microsoft Office Outlook 12.0 >Thread-Index: xyxyzyzy >Content-Language: en-us >X-Mailman-Approved-At: Wed, 09 May 2012 21:43:22 +0000 >Subject: [Example Discussion 110] Re: Example Subject >X-BeenThere: l...@lists.example.com >X-Mailman-Version: 2.1.14 >Precedence: list >Reply-To: Example Discussion <l...@lists.example.com> >List-Id: Example Discussion <all.lists.example.com> >List-Unsubscribe: <http://lists.example.com/m/options/all>, > <mailto:all-requ...@lists.example.com?subject=3Dunsubscribe> >List-Archive: <http://lists.example.com/archive/all> >List-Post: <mailto:l...@lists.example.com> >List-Help: <mailto:all-requ...@lists.example.com?subject=3Dhelp> >List-Subscribe: <http://lists.example.com/m/listinfo/all>, > <mailto:all-requ...@lists.example.com?subject=3Dsubscribe> >Content-Type: multipart/mixed; >boundary=3D"=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D425472280456034579= >5=3D=3D" >Errors-To: all-boun...@lists.example.com >Sender: all-boun...@lists.example.com -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
