How to Install PostfixAdmin on a Bitnami LAMP Stack

I was been searching for this topic myself but didn’t find a good post/ tutorial, hence again I will provide you with a short briefing of my own findings while researching how to install PostfixAdmin on a Bitnami Ubuntu setup on AWS.

Credit is due where credit is deserved, and to be honest the following post on Linuxize has helped me a lot, although it had some challenges:

• https://linuxize.com/post/set-up-an-email-server-with-postfixadmin

Some things to bear in mind are:

• Check which version is the latest. The article says 3.1 while the latest PostfixAdmin release is 3.2.
• All PostfixAdmin PHP files have moved to the postfixadmin/public/ directory, including upgrade.php, so make sure to update your path as follows:

/var/www/postfixadmin/public/upgrade.php

• And finally, the PostfixAdmin-CLI has another add admin command, so I suggest you use the following which walks you through the configuration for adding a super user:

sudo bash /var/www/postfixadmin/scripts/postfixadmin-cli admin add

To make it work, you will have to set-up your VirtualHost configuration as follows:

<VirtualHost _default_:443>
    ServerName mail.domain.com
    DocumentRoot "/var/www/postfixadmin/public"

    SSLEngine on
    SSLCertificateFile "/opt/bitnami/apache2/conf/server.crt"
    SSLCertificateKeyFile "/opt/bitnami/apache2/conf/server.key"
 
    <Directory "/var/www/postfixadmin/">
        Options Indexes
        AllowOverride None
 
        <IfVersion < 2.3 >
            Order allow,deny
            Allow from all
        </IfVersion>
        <IfVersion >= 2.3 >
            Require all granted
        </IfVersion>
    </Directory>
</VirtualHost>

And finally, you can access the PostfixAdmin configuration panel on the subdomain you configured, which is mail.domain.com in the example given.
