Hi My mailserver (mail.bitcetera.com) is behind a router that gets a dynamic IP (87.221.120.44) from the ISP. In order to prevent outgoing mail from being considered spam due to the dynamic IP, I've configured the ISP's mailserver as relayhost.
Unfortunately, Yahoo still throws my mails in the spam folder. I've tried using the generic DN for the dynamic IP (44.120.221.87.dynamic.jazztel.es) as myhostname, but that doesn't help. Any idea why and what I could do to prevent this? Here are the headers of a mail to Yahoo: Return-Path: <sv...@delirium.ch> Authentication-Results: mta161.mail.re3.yahoo.com from=delirium.ch; domainkeys=neutral (no sig); from=delirium.ch; dkim=neutral (no sig) Received: from 62.14.3.171 (EHLO smtp02.jazztel.es) (62.14.3.171) by mta161.mail.re3.yahoo.com with SMTP; Thu, 16 Apr 2009 08:00:36 -0700 Received: from [87.221.120.44] (helo=mail.bitcetera.com) by smtp02.jazztel.es with esmtpa (Exim 4.69) (envelope-from <sv...@delirium.ch>) id 1LuT4A-0004LO-RS for mytestac...@yahoo.de; Thu, 16 Apr 2009 16:59:50 +0200 Received: from samba.bitcetera.com (samba.bitcetera.com [192.168.118.20]) (using TLSv1 with cipher AES128-SHA (128/128 bits)) (No client certificate requested) by mail.bitcetera.com (Postfix) with ESMTPSA id 4856A396378 for <mytestac...@yahoo.de>; Thu, 16 Apr 2009 17:00:31 +0200 (CEST) Message-Id:<e06035fb-c3d8-41d3-aa1c-93f0cdfd0...@delirium.ch> From: <sv...@delirium.ch> To: mytestac...@yahoo.de Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 7bit Mime-Version: 1.0 (Apple Message framework v930.3) Subject: testlikon Date: Thu, 16 Apr 2009 17:00:30 +0200 Content-Length: 10 Thanks for your help!
