Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I would not trust RoadRunner. RoadRunner is AOL. AOL, Earthlink, Mindspring, RR, are all owned by AOL and are working with MAPS to block email at the IP level. This is an absurd attempt to stop spam mail because it blocks legitimate mail too. I cannot email any of their users, yet I have never spammed.
I've been able to circumvent the problem, but I've decided not to email those users anyway; doing so would be contributing to the censorship problem. It's an erosion of civil liberties. You guys should not be giving Road Runner your money.. you are contributing to the denial of service problem, even if they don't block your outgoing packets.
I have STILL been unable to find a work around for my problem. I even tried setting up postfix to relay my outgoing messages through my isp's smtp server with this command:
relayhost = smtp-server.mn.rr.com
But.. it still gets kicked back.
Here is the full message header of one of my messages that got bounced back:
Received: by pwk.ath.cx (Postfix)
id 639C917B5C0; Sat, 9 Aug 2003 15:43:07 -0400 (EDT)
Date: Sat, 9 Aug 2003 15:43:07 -0400 (EDT)
From: MAILER-DAEMON@pwk.ath.cx (Mail Delivery System)
Subject: Undelivered Mail Returned to Sender
Content-Type: multipart/report; report-type=delivery-status;
So it looks to me like it can't get out of my network for some reason, if I'm reading this correctly. Could someone please help me interpret this better? Perhaps offer some more troubleshooting tips? PLEASE?
FYI: You don't have the ability to accept email for a yahoo.com domain unless of course you are within your own private LAN and then you can recieve it for whomever you'd like (BillGates@microsoft.com if it resolves fine). But sending mail to your server isn't going to recieve it for a yahoo.com ID. Well, not without some tweaking:
#relay_domains = $mydestination
relay_domains = $mydestination,yahoo.com
It's mine.. through dyndns, and I agree, messages can come through to my server but outgoing messages don't seem to be able to get out. I can ping anything from the server which means dns "seems to be" working.. ugh, I just don't get it.
Straight outta your postfix/main.cf from above:
# By default, Postfix relays mail
# - from "trusted" clients whose IP address matches $mynetworks,
# - from "trusted" clients matching $relay_domains or subdomains thereof,
# - from untrusted clients to destinations that match $relay_domains
# or subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.
So you'll wanna make sure those things are set properly. Your 'mydomain' and 'myhostname' aren't even set, you'll wanna set those.
I'd have to guess 'yeah' but maybe not... Even if you are blocked, you should be able to relay through your ISP's mail server, unless they of course block themselves or relaying from unknown hosts (in which case though, I'd think that using your IP would work? , unless then they have only allowed specifically from a set of IP's they assign themselves..).
For kicks, see if you can setup postfix from the source tarball on www.postfix.org Alternatively, troubleshoot with another mail server ( Exim probably being the one I'd suggest first, and then Qmail ).
