SquirrelMail is a popular open-source webmail system that allows users to access their email accounts through a web interface. If you're running POP! OS Latest and would like to install SquirrelMail, then this tutorial is for you. We'll guide you through the steps of installing SquirrelMail on your system.
Before we begin, you'll need to have the following:
To ensure that your system is up-to-date, run the following command:
sudo apt update
sudo apt upgrade
SquirrelMail requires a web server to work. We'll install Apache first.
sudo apt install apache2
Once Apache is installed, start the webserver using the following command:
sudo systemctl start apache2
Verify that Apache is running by visiting your server's IP address in a web browser. You should see the Apache2 Ubuntu Default Page.
SquirrelMail is written in PHP, which means we need to install PHP and its extensions to run the webmail client.
sudo apt install php libapache2-mod-php php-mbstring php-gd php-xml
After installation is complete, restart Apache:
sudo systemctl restart apache2
Now that we have Apache and PHP installed, it's time to download and install SquirrelMail.
cd /tmp
wget https://sourceforge.net/projects/squirrelmail/files/stable/1.4.23/squirrelmail-webmail-1.4.23.tar.gz
Extract the downloaded file:
tar -xzvf squirrelmail-webmail-1.4.23.tar.gz
Copy the extracted files to the root directory of your web server:
sudo cp -r squirrelmail-webmail-1.4.23 /var/www/html/squirrelmail
Set the correct permissions:
sudo chown -R www-data:www-data /var/www/html/squirrelmail
Before we can use SquirrelMail, we need to configure it to work with our email client.
cd /var/www/html/squirrelmail/config
sudo cp config_default.php config.php
Edit the config file:
sudo nano config.php
Look for the following configuration options and update them with your server's information:
$domain = 'example.com';
$imapServerAddress = 'localhost';
$imapPort = 993;
$use_imap_tls = true;
$smtpServerAddress = 'localhost';
$smtpPort = 587;
$use_smtp_tls = true;
$smtp_auth_mech = 'login';
$smtp_user = '%u';
$smtp_pass = '%p';
Save and exit the file.
Now that SquirrelMail is installed and configured, it's time to access it through a web browser.
Open your browser and go to the following URL:
http://your_server_ip/squirrelmail
You'll be asked to log in with your email address and password. Once logged in, you'll be taken to your inbox.
Congratulations, you've successfully installed SquirrelMail on your POP! OS Latest server! You can now access your email account through a web interface.
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!
