THE DEFINITIVE GUIDE TO SETTING UP A LINUX RELAY SERVER FOR MICROSOFT EXCHANGE SERVER 2000/2003

There are a couple of linux how-tos floating on the Internet that deal with this very subject. As a matter of fact, those guides are what inspired to write this one. In the spirit of keeping it simple, let me recommend the Mandrake or as it’s currently known Mandriva Linux distro. This guide has been written with this distro in mind.

What you will need:

  1. Mandriva Linux Limited Edition 2005 (I’m sure this will work on Mandrake 10.1 or even older versions. I just haven’t tested it on anything earlier)
  2. A box with a DVD-ROM for the DVD version of Mandriva LE 2005 or CD-ROM for the CD version of Mandriva LE 2005. (The system specs do not have to be very high. It’s basically going to be a mail server. Depending on the amount of mail you expect, size the machine accordingly. I installed it on an IBM eServer with a single Xeon CPU, Hardware RAID1 and 512MB of RAM. I know it’s overkill for this application, but the server choice wasn’t my call).
  3. A Ms Exchange 2000/2003 box that you want to protect. You don't know how to setup an Exchange server you say? Well then, check out my super dooper "Down and Dirty Guide to setting up Exchange 2000/2003" at this address: http://forums.theonpc.com/viewtopic.php?t=15
  4. A live working Internet connection (Preferrably broadband).

STEP 1: Install Mandriva LE 2005 Install Mandriva LE 2005 with the following minimum packages:

  • Mail server (Postfix)
  • SSH server

STEP 2: Remove Installation Media/Update Mandriva Sources:

It’s important to remove the installation DVD or CD-ROM as the media of choice for your Linux installation and instead use on-line media anytime we want to install or update anything on this installation. The procedures below will help you accomplish this:

a) Create a script file under /root called update.sh or whatever you want. I usually name them by distro. For example, for 2005 LE, I name it "update.2005.sh". Open up a ssh (putty) windows to your server. It's a lot easier doing it though putty than trying to type the sources in a console window manually. In a putty window it's just a matter of copy and paste. In the putty windows type the following:

vi update.2005.sh

Enter the following lines:

urpmi.removemedia -a

urpmi --auto-select --auto

b) Goto http://easyurpmi.zarb.org and select your distro and then click on the "Proceed to STEP 2 button. Then, under "2) Select a mirror for each source" section under Core Distribution, check off the following: "Source contrib", "Source main", "Source updates" as a bare minimum. Then click on the Proceed to STEP 3 button. This will generate a list of mirrors. Select them and copy the entire list. Go back to your putty window, click the "i" key to put the editor in insert mode and paste what you just copied from your browser in your putty window between the lines you type earlier. So, your screen should look similar to this:

urpmi.removemedia -a

urpmi.addmedia --update updates ftp://ftp.clinet.fi/pub/mirrors/Mandrake-linux/official/updates/LE2005/main_updates/ with media_info/hdlist.cz

urpmi.addmedia main ftp://ftp.clinet.fi/pub/mirrors/Mandrake-linux/official/2005/i586/media/main with media_info/hdlist.cz

urpmi.addmedia contrib ftp://ftp.clinet.fi/pub/mirrors/Mandrake-linux/official/2005/i586/media/contrib with media_info/hdlist.cz

urpmi --auto-select --auto

Of course, don't copy my sources which are most likely outdated. c) Save your script and make it executable. Type the following in your putty window: Presss the "ESC" key to take the editor out of insert mode. Then press "SHIFT ZZ" to save your file.

chmod 755 update.2005.sh

c) You are ready to go. Type the following in your putty window and watch it go. Once completed, your sources are updated and your installation media has been removed.

./update.2005.sh

This is an excelent guide step by step to build a mail gateway with antivirus and antispam funcionalities. I've used it to build a mail gateway to help to us domino's server to process email. I've build it with Mandriva 2006 and there's not problem, all works fine. As I didn't have Exchange, I had to look for information to build the file of valid recipients manually.
