To install apache2 you refer to HTTPD Installation section for details.

To install Exim4 you run the following commands at a terminal prompt:

sudo apt-get install exim4 sudo apt-get install exim4-base sudo apt-get install exim4-config

Once exim4 is installed, the configuration files are stored in the /etc/exim4 directory. In Ubuntu, by default, the exim4 configuration files are split across different files. You can change this behavior by changing the following variable in the /etc/exim4/update-exim4.conf file:

To install Mailman, run following command at a terminal prompt:

sudo apt-get install mailman

It copies the installation files in /var/lib/mailman directory. It installs the CGI scripts in /usr/lib/cgi-bin/mailman directory. It creates list linux user. It creates the list linux group. The mailman process will be owned by this user.

Once apache2 is installed, you can add the following lines in the /etc/apache2/apache2.conf file:

Alias /images/mailman/ "/usr/share/images/mailman/" Alias /pipermail/ "/var/lib/mailman/archives/public/"

Mailman uses apache2 to render its CGI scripts. The mailman CGI scripts are installed in the /usr/lib/cgi-bin/mailman directory. So, the mailman url will be http://hostname/cgi-bin/mailman/. You can make changes to the /etc/apache2/apache2.conf file if you wish to change this behavior.

Once Exim4 is installed, you can start the Exim server using the following command from a terminal prompt:

sudo apt-get /etc/init.d/exim4 start

In order to make mailman work with exim4, you need to configure exim4. As mentioned earlier, by default, exim4 uses multiple configuration files of different types. For details, please refer to the Exim website. To run mailman, we should add new a configuration file to the following configuration types:

Exim creates a master configuration file by sorting all these mini configuration files. So, the order of these configuration files is very important.

All the configuration files belonging to the main type are stored in the /etc/exim4/conf.d/main/ directory. You can add the following content to a new file, named 04_exim4-config_mailman:

# start # Home dir for your Mailman installation -- aka Mailman's prefix # directory. # On Ubuntu this should be "/var/lib/mailman" # This is normally the same as ~mailman MM_HOME=/var/lib/mailman # # User and group for Mailman, should match your --with-mail-gid # switch to Mailman's configure script. Value is normally "mailman" MM_UID=list MM_GID=list # # Domains that your lists are in - colon separated list # you may wish to add these into local_domains as well domainlist mm_domains=hostname.com # # -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # # These values are derived from the ones above and should not need # editing unless you have munged your mailman installation # # The path of the Mailman mail wrapper script MM_WRAP=MM_HOME/mail/mailman # # The path of the list config file (used as a required file when # verifying list addresses) MM_LISTCHK=MM_HOME/lists/${lc::$local_part}/config.pck # end

All the configuration files belonging to transport type are stored in the /etc/exim4/conf.d/transport/ directory. You can add the following content to a new file named 40_exim4-config_mailman:

mailman_transport: driver = pipe command = MM_WRAP \ '${if def:local_part_suffix \ {${sg{$local_part_suffix}{-(\\w+)(\\+.*)?}{\$1}}} \ {post}}' \ $local_part current_directory = MM_HOME home_directory = MM_HOME user = MM_UID group = MM_GID

All the configuration files belonging to router type are stored in the /etc/exim4/conf.d/router/ directory. You can add the following content in to a new file named 101_exim4-config_mailman:

mailman_router: driver = accept require_files = MM_HOME/lists/$local_part/config.pck local_part_suffix_optional local_part_suffix = -bounces : -bounces+* : \ -confirm+* : -join : -leave : \ -owner : -request : -admin transport = mailman_transport

Once mailman is installed, you can run it using the following command:

sudo /etc/init.d/mailman start

Once mailman is installed, you should create the default mailing list. Run the following command to create the mailing list:

sudo /usr/sbin/newlist mailman

Enter the email address of the person running the list: bhuvan at ubuntu.com Initial mailman password: To finish creating your mailing list, you must edit your /etc/aliases (or equivalent) file by adding the following lines, and possibly running the `newaliases' program: ## mailman mailing list mailman: "|/var/lib/mailman/mail/mailman post mailman" mailman-admin: "|/var/lib/mailman/mail/mailman admin mailman" mailman-bounces: "|/var/lib/mailman/mail/mailman bounces mailman" mailman-confirm: "|/var/lib/mailman/mail/mailman confirm mailman" mailman-join: "|/var/lib/mailman/mail/mailman join mailman" mailman-leave: "|/var/lib/mailman/mail/mailman leave mailman" mailman-owner: "|/var/lib/mailman/mail/mailman owner mailman" mailman-request: "|/var/lib/mailman/mail/mailman request mailman" mailman-subscribe: "|/var/lib/mailman/mail/mailman subscribe mailman" mailman-unsubscribe: "|/var/lib/mailman/mail/mailman unsubscribe mailman" Hit enter to notify mailman owner... #

We have configured exim to recognize all emails from mailman. So, it is not mandatory to make any new entries in /etc/aliases. If you have made any changes to the configuration files, please ensure that you restart those services before continuing to next section.
