How to Install Briefkasten on FreeBSD Latest

Briefkasten is a self-hosted mail server and inbox system that uses PGP (Pretty Good Privacy) encryption for security. In this tutorial, we will guide you through the process of installing Briefkasten on FreeBSD Latest.

Requirements

Before proceeding with the installation process, make sure that your system meets the following requirements:

• FreeBSD Latest installed and running
• Root access to the server
• Basic knowledge of command-line interface (CLI)

Step 1: Install dependencies

First, we need to install the dependencies required for Briefkasten to work. We can do this using the following command:

sudo pkg install go git

Step 2: Download Briefkasten

Next, we need to download the Briefkasten source code from its GitHub repository. We can do this using the following commands:

git clone https://github.com/ndom91/briefkasten.git
cd briefkasten

Step 3: Build and install Briefkasten

With the source code downloaded, we can now build and install Briefkasten. We can do this using the following commands:

go build
sudo mv briefkasten /usr/bin/briefkasten
sudo cp config.example.json /etc/briefkasten.json

Step 4: Configure Briefkasten

Finally, we need to configure Briefkasten before we can start using it. We can do this by editing the briefkasten.json file using our preferred text editor, such as nano:

sudo nano /etc/briefkasten.json

In the configuration file, we need to specify the domain name, email address, and other settings. For example:

{
    "domain_name": "example.com",
    "email_address": "[email protected]",
    "pgp_key": "-----BEGIN PGP PUBLIC KEY BLOCK-----\n...",
    "http_port": "80",
    "https_port": "443",
    "tls_cert_file": "/path/to/tls/cert/file.crt",
    "tls_key_file": "/path/to/tls/key/file.key",
    "log_level": "info",
    "database": {
        "type": "sqlite3",
        "connection": "/var/db/briefkasten.db"
    }
}

Once you have made the necessary changes, save and exit the file.

Step 5: Start the Briefkasten service

With Briefkasten configured, we can now start the service using the following command:

sudo briefkasten

You should see output indicating that the service is running. Briefkasten will listen on the specified ports (HTTP or HTTPS), and you can access it using your web browser.
