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 am configuring a mail server using Postfix, no sweat. The mail server will serve a small office and will reside with a web server (apache- it works fine) on the same linux box (RH 7.1). The mail server sits behind a router which is configured to forward port 25 to my mail server. From my client computer (using pop3) on the lan I can send mail out through the mail server however, I cannot receive mail into the mail server.
I have configured the mx file with my registrar (register.com) to point to my mail server. Do I have to do anything else DNS wise on my mail server?
Okay, I answered my own question.
I rechecked my mx file with my registrar and it appears that there was an error there. After correcting that file and waiting over the weekend my mail server now recieves mail messages from the Internet- cool.
What was the error with the MX entry? I am basically having the same problem with postfix. I can use it locally but if I try to connect from another machine on my network or if anyone sends mail to someone on my server it does not respond. Basically they get an error message back a couple days later saying the connection has timed out.
I didn't have access to the domain account at register.com (my boss did). When I finally got around to checking the configuration at the registrar, I noticed that under the mx file there was an additional entry regarding the actual host name of the mail server. I just typed in the correct name and everything worked great!
P.S. There is a great book on Postfix- "Postfix" by Richard Blum
Hi all,
I'm new at this forum and also new with Linux too. I bought a fixed IP and registered my domain at Yahoo. I can setup a web server (just basic) and now I'm looking for information to show me how to setup FTP & mail server. I don't know if I put a router (D-Link 804) will effect to this or not (I choose open port 80; 21; 25) but seem like I can't set thing up. For FTP can connect but can not upload file. For SendMail I can only use this server to send mail out. I heard that Postfix is more easier but I have no success at all. If anyone know when do I can get Step by Step set up mail server please so me. Or if you can post a sample page is a big thanks. .
1 more thing: how do I set up POP3 on my server.
ps. I looked posfix.com & RH, MD, sendmail.org but can't do setup
Well it sounds like you are where I was a few days ago, So try this:
Open a shell
type su - 'Make sure you use the hyphen I have run into ALOT of problems with Redhat Linux 7.2 if I don't use the hyphen
type in your root password when prompted
type 'setup'
Goto Firewall Configuration
Select Customize
Select the services you would like to allow
Exit Setup
This will automatically restart your services
If your problem was the same as mine then this should fix it up for you, if not, let me know and I will try to help you further as I ran across alot of information in my seaching.
I turned off firewall (selected no firewall) when I installed Linux. And I think my problem now is not know how to setup mail configuration file. If you have a sample page please post and explain how it work. I trully appreciate that.
Okay, well I am using Postfix and I assume you are using Sendmail, But who knows, maybe it will help...Oh BTW you have to open port 110 for the POP server as well...
I will post my main.cf file tomorrow when I add some comments to it, to hopefully explain why I did what I did.
