## Install Ubuntu 12.04 with the package groups:
![screenshot of package group selection screen](https://raw.github.com/discourse/discourse-docimages/master/install/ubuntu%20-%20install%20-%20software%20selection.png)
* Basic ubuntu server
* OpenSSH server
* Mail server
* PostgreSQL database (9.1+)
You may be working on an already-installed or automatically deployed system, in which case you can install them afterwards:
# Run these commands as your normal login (e.g. "michael")
sudo apt-get update && sudo apt-get -y upgrade
sudo tasksel install openssh-server
sudo tasksel install mail-server
sudo tasksel install postgresql-server
### Configure the mail server:
![screenshot of mail server type configuration screen](https://raw.github.com/discourse/discourse-docimages/master/install/ubuntu%20-%20install%20-%20mail_1%20system%20type.png)
In our example setup, we're going to configure as a 'Satellite system', forwarding all mail to our egress servers for delivery. You'll probably want to do that unless you're handling mail on the same machine as the Discourse software.
![screenshot of mail name configuration screen](https://raw.github.com/discourse/discourse-docimages/master/install/ubuntu%20-%20install%20-%20mail_2%20mailname.png)
You probably want to configure your 'mail name' to be the base name of your domain. Note that this does not affect any email sent out by Discourse itself, just unqualified mail generated by systems programs.
![screenshot of relay host configuration screen](https://raw.github.com/discourse/discourse-docimages/master/install/ubuntu%20-%20install%20-%20mail_3%20relayconfig.png)
If you have a mail server responsible for handling the egress of email from your network, enter it here. Otherwise, leave it blank.
