Hi - I have been trying to configure sendmail so I can run it on my local server at home, which is connected to the net via a DSL connection with a dynamic IP address.
I host my domains and websites from this server, and use a script with zoneedit.com to keep my domain name dns entries mapped to my dynamic ip (which rarely seems to change anyway) and this all works fine. I also have sendmail configured ok so I can send and receive email ok. What is driving me nuts is the dynamic ip blacklists that result in the majority of my emails being bounced from mailservers that consider my dynamic IP address to be the originator of spam. I think this is a pretty broad (and wrong) assumption, but anyway, heres my problem try to get round this: I've read on abuse.net that I can configure sendmail to relay my email via my ISP's smtp server, so it appears to come from them, rather than my ip address. I am using Redhat 8.0. Heres what I added to /etc/mail/sendmail.mc: define(`SMART_HOST',`mail.yourisp.net')dnl MASQUERADE_AS(kevinhooke.com)dnl FEATURE(`allmasquerade')dnl FEATURE(`masquerade_envelope')dnl replacing mail.yourisp.net with sbcglobal/yahoo's smtp server. I then updated this with: m4 sendmail.mc > sendmail.cf then restarted my sendmail server with: /etc/init.d/sendmail restart Server starts ok, everything looks good. When I send mail, I can see in /var/log/maillog that the email was relayed via mx1.mail.yahoo.com (I think). The email that is actually sent though still has info about my own server and my dynamic IP address, which means the email is still getting blacklisted/blocked as spam. Heres the headers: X-Apparently-To: [EMAIL PROTECTED] via 66.218.93.88; Sat, 03 Jan 2004 13:32:42 -0800 X-YahooFilteredBulk: 64.165.71.234 Return-Path: <[EMAIL PROTECTED]> Received: from 64.165.71.234 (EHLO linuxsvr.localdomain) (64.165.71.234) by mta207.mail.scd.yahoo.com with SMTP; Sat, 03 Jan 2004 13:32:42 -0800 Received: from thebeast ([192.168.0.3]) by linuxsvr.localdomain (8.12.8/8.12.8) with ESMTP id i03LWf11031162 for <[EMAIL PROTECTED]>; Sat, 3 Jan 2004 13:32:42 -0800 Message-ID: <[EMAIL PROTECTED]> From: "Kevin Hooke" <[EMAIL PROTECTED]> Add to Address Book To: "Kev" <[EMAIL PROTECTED]> Subject: test from pc Date: Sat, 3 Jan 2004 13:32:55 -0800 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2800.1158 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1165 Content-Length: 1 This was an email sent from Outlook on my Windows XP machine, via my sendmail mailserver for my kevinhooke.com domain on my linux box, to a test email address [EMAIL PROTECTED] I was expecting from what I read on the abuse.net site that relaying via my isp's smtp server would solve the dynamic ip blacklisting problems, but apparently it hasn't or I am misunderstanding something. Any ideas? I only know a little linux (enough to get me in trouble apparently), so please be explicit with any instructions! :-) If anyone knows of any website/how-tos that may help, that would be appreciated too!
