 NEXT - STEP 8

Step 7. Install the Postfix mail server

DSpace needs to send emails in order to facilitate submission workflows etc.

Ideally before setting this up, you should speak to your campus email administrator.

Local Postfix Email Sending Server Installation

Step 7.1: First we purge old software

Type the following;

sudo dpkg --purge exim4

Step 7.2: Then we install the Postfix software

Install the Postfix mail server by typing as follows;

When asked for type of setup, select "Internet with Smarthost".

The "Smarthost" is your campus email sending server, read the wiki page below for alternatives, if you do not have a campus email sending server.

See links below for more detail before continuing.

sudo apt-get install postfix

Step 7.3: Finally we setup a default mailname

Now we edit the servers "mailname" by typing as follows:

sudo nano /etc/mailname

Add one line only which should be the hostname (URL) of your server, for example: scholar.sun.ac.za.

-Install the postfix mail server as follows:

- sudo apt-get install postfix
-===Step 7.2: Review the mail server config files===
-If you are satisfied with the installation of Postfix using the step above, you may skip this step. Otherwise continue below.
-To review the Postfix '''main.cf''' file, type as follows:
- sudo nano /etc/postfix/main.cf
-''Tip: It is always a good idea to maximise the open nano window so that the copy and paste of long lines does not wrap around.''
-See below for an example of the config file:
-<pre>
-# See /usr/share/postfix/main.cf.dist for a commented, more complete version
-# Debian specific:  Specifying a file name will cause the first
-# line of that file to be used as the name.  The Debian default
-# is /etc/mailname.
-#myorigin = /etc/mailname
-smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
-biff = no
-# appending .domain is the MUA's job.
-append_dot_mydomain = no
-# Uncomment the next line to generate "delayed mail" warnings
-#delay_warning_time = 4h
-readme_directory = no
-# TLS parameters
-smtpd_tls_cert_file=/etc/ssl/certs/%hostname%.pem
-smtpd_tls_key_file=/etc/ssl/certs/%hostname%.key
-smtpd_use_tls=yes
-smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
-smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
-# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
-# information on enabling SSL in the smtp client.
-myhostname = %hostname%
-alias_maps = hash:/etc/aliases
-alias_database = hash:/etc/aliases
-myorigin = /etc/mailname
-mydestination = %hostname% localhost
-relayhost = %relay-hostname%
-mynetworks = %my-subnet% 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
-mailbox_size_limit = 0
-recipient_delimiter = +
-inet_interfaces = all
-</pre>
-# Change the ''' %hostname%''' to the hostname of your server.
-# Change the '''%relay-hostname%''' to the hostname of your campus email server which sends and delivers email.
-# Add the subnet of your campus TCP/IP network '''%my-subnet%''' to the '''mynetworks''' parameter.
-# Ensure '''mydestination = %hostname% localhost''' to prevent your mail server becoming a spam email relay.
-Talk to the campus system administrator about these settings.
-Also see: http://www.postfix.org/SMTPD_ACCESS_README.html and http://en.wikipedia.org/wiki/Subnet_Mask.
-The postfix server can be re-configured by typing the following:
- sudo dpkg-reconfigure postfix
-===Step 7.3: Setup default mailname===
 Now we edit the servers "mailname" by typing as follows:
   sudo nano /etc/mailname
-Add one line only which should be the hostname of your server.
+Add one line only which should be the hostname (URL) of your server, for example: ''scholar.sun.ac.za''.
-See example below.
-<pre>
-repository.sun.ac.za
-</pre>
-Now we restart Postfix by typing as follows:
- sudo service postfix restart
-===Step 7.4: Setup the email aliases===
-Now we nees to forward any email sent to local accouns on the server to email accounts of persons responsible for the repository.
-The "root" and "dspace user" email address forwarding are setup as follows.
-Type the following.
- sudo nano /etc/aliases
-Add aliases as per example below:
-<pre>
-# Added by installer for initial user
-root:   me@my.edu.ac.za
-dspace: me@my.edu.ac.za
-</pre>
-Change the '''me@my.edu.ac.za''' to your email address.
-To activate the new aliases type the following:
- sudo newaliases
-===Step 7.5: Send a test email to root===
-Install the command line mailer program as follows:
- sudo apt-get install mailutils
-Now we can send a test email to the root user by typing as follows:
- mail -s "Test Email from root" root
-Press the "Enter" key and type some message content. Press '''CTL+D''' twice and then '''Enter''' to send the mail.
-Check the following log for any delivery errors as follows:
+==Optional Extras==
- sudo tail -n 20 /var/log/mail.log
+*[[SUNScholar/Prepare Ubuntu/S07/Alternatives|Alternative Sender Email Server Gateway Choices]]
-If there are no delivery errors then your mail server is setup.

+*[[SUNScholar/Prepare Ubuntu/S07/Testing|Email Tests]]
-;Well done.
