==== Install GNU Mailman on Debian/Ubuntu ====

Install GNU Mailman and dependencies
<code>
sudo apt-get install mailman postfix
</code>

Link mailman apache configuration
<code>
sudo ln -s /etc/mailman/apache.conf /etc/apache2/conf-available/mailman-apache.conf
</code>

Edit ''mailman.conf'' to remove cgi-bin reference
<code>
sudo vi /etc/apache2/conf-available/mailman-apache.conf
</code>

Edit ''mm_cfg.py'' to match removal of cgi-bin
<code>
sudo vi /etc/mailman/mm_cfg.py
</code>

Enable new configuration and reload apache
<code>
sudo a2enconf mailman-apache.conf
sudo a2enmod cgi
sudo service apache2 reload
</code>

Create a space to store list configuration files
<code>
sudo mkdir /etc/mailman/lists
</code>

Setup environment to separate system aliases from list aliases
<code>
sudo mv /etc/aliases /etc/aliases-system
sudo touch /etc/aliases
sudo touch /etc/mailman/lists/README
</code>

Build your first list. The ''mailman'' list is required for proper functioning of the system otherwise the Mailman Master Queue Runner service will fail to start. The ''.info'' file is purely for house-keeping purposes in large-scale implementations.
<code>
sudo sh -e -c "newlist --quiet --automate mailman listowner@yoursite.tld insecurepassword | grep -A 12 ^# > /etc/mailman/lists/mailman.conf"
sudo sh -e -c 'echo "Ticket: \nDepartment: \nRequestor: \n" > /etc/mailman/lists/mailman.info'
</code>

Build ''/etc/aliases'' from ''/etc/aliases-system'' and ''/etc/mailman/lists/*.conf''
<code>
sudo sh -c "cat /etc/aliases-system /etc/mailman/lists/*.conf > /etc/aliases"
sudo newaliases
</code>

Start mailman
<code>
sudo service mailman start
</code>

==== Notes ====

  * Missing sitelist
    * Mailman needs a so-called "site list", which is the list from which password reminders and such are sent out from.  This list needs to be created before mailman will start. To create the list, run "newlist mailman" and follow the instructions on-screen.  Note that you also need to start mailman after that, using /etc/init.d/mailman start.
