Installing IMP on Debian

IMP is a feature-rich webmail client that is part of the Horde framework. In this tutorial, we will show you how to install IMP on Debian.

Prerequisites

Before we get started, make sure you have the following prerequisites:

• Debian Latest installed
• Root access to the server
• A web server installed (such as Apache or Nginx)
• PHP installed

Step 1: Update the system

The first step is to update the system by running the following command:

apt-get update && apt-get upgrade -y

Step 2: Install the required packages

Next, we need to install the required packages for IMP. Run the following command to do this:

apt-get install php-cli php-curl php-gd php-imap php-json php-ldap php-mbstring php-pear php-xml php-zip

After this completes, restart PHP by running:

systemctl restart php7.4-fpm

Step 3: Install IMP

Now we can install IMP using PEAR. Run the following command:

pear install horde/webmail_imp

Step 4: Configure IMP

Once IMP is installed, we need to configure it. First, create a new virtual host in your web server configuration to point to the directory /usr/share/php/Horde/IMP. Here is an example configuration for Apache:

<VirtualHost *:80>
    ServerName webmail.example.com

    DocumentRoot /usr/share/php/Horde/IMP
    <Directory /usr/share/php/Horde/IMP>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
        Require all granted
    </Directory>
</VirtualHost>

Configuring the database

Next, we need to configure the database for IMP. Copy the file /usr/share/php/Horde/IMP/config/conf.xml.dist to /usr/share/php/Horde/IMP/config/conf.xml by running:

cp /usr/share/php/Horde/IMP/config/conf.xml.dist /usr/share/php/Horde/IMP/config/conf.xml

Now edit the file /usr/share/php/Horde/IMP/config/conf.xml to set the database details. Here is an example configuration for a MySQL database:

<config>
    <sql>
        <params>
            <driver>pdo_mysql</driver>
            <host>localhost</host>
            <port>3306</port>
            <username>webmail</username>
            <password>password</password>
            <database>imp</database>
        </params>
    </sql>
</config>

Creating the database schema

Finally, we need to create the database schema for IMP. Run the following command:

/usr/share/php/Horde/IMP/bin/horde-db-migrate

Step 5: Accessing IMP

IMP should now be accessible at the virtual host you created in step 4. In our example, this would be at http://webmail.example.com. Login with your email address and password to start using IMP.

Conclusion

That's it! You have successfully installed and configured IMP on Debian.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
