Update the system by running the following commands in the terminal.

Install Apache, PHP, and MySQL by running the following command:

sudo pkg_add apache-httpd-2.4.46p2.tgz php-7.4.13.tgz php-pdo_mysql-7.4.13.tgz mysql-client-5.7.32v0.tgz mysql-server-5.7.32v0.tgz php-mysqlnd-7.4.13.tgz

Configure MySQL by running the following commands:

sudo /usr/local/bin/mysql_install_db --user=_mysql
sudo cp /usr/local/share/mysql/my-medium.cnf /etc/my.cnf
sudo /etc/rc.d/mysql start

Create a database for Roundcube:

mysql -u root -p

You will be prompted to enter the root password.

create database roundcubemail;
grant all privileges on roundcubemail.* to roundcube_user@localhost identified by 'your_password';
flush privileges;
exit

Download Roundcube from the official website by running the following commands:

cd /var/www/htdocs

cd roundcube
sudo ftp https://github.com/roundcube/roundcubemail/releases/download/1.4.10/roundcubemail-1.4.10-complete.tar.gz

Extract the downloaded file by running the following command:
```
sudo tar zxvf roundcubemail-1.4.10-complete.tar.gz
```
Rename the extracted directory to "webmail" by running the following command:
```
sudo mv roundcubemail-1.4.10 webmail
```

Create a configuration file by running the following command:

sudo cp webmail/config/config.inc.php.sample webmail/config/config.inc.php

Edit the configuration file using your favorite text editor by running the following command:
```
sudo vim webmail/config/config.inc.php
```

Update the following parameters in the configuration file:

$config['db_dsnw'] = 'mysql://roundcube_user:your_password@localhost/roundcubemail';
$config['default_host'] = 'localhost';

Save and exit the configuration file.
Change the ownership of the Roundcube directory to the Apache user by running the following command:
```
sudo chown -R www:www webmail
```
