How to Install Stalwart JMAP on OpenBSD

In this tutorial, you will learn how to install Stalwart JMAP on OpenBSD. Stalwart JMAP is a JavaScript Message Access Protocol server that allows for email sending and querying via an API.

Prerequisites

Before starting, ensure you have the following:

• An OpenBSD server with a non-root user with sudo privileges.
• A domain name that you wish to use with Stalwart JMAP.
• A public IP address associated with your server.

Step 1: Update the System

The first step is to ensure your OpenBSD system is up to date. To do this, log in to your server and run the following command:

sudo pkg_add -u

Step 2: Install the Required Dependencies

Next, you need to install the required dependencies. Run the following command:

sudo pkg_add node yarn libressl

Step 3: Clone the Stalwart JMAP Repository

Now you need to clone the Stalwart JMAP repository. Run the following command:

git clone https://github.com/stalwart-jmap/stalwart.git

Step 4: Install Stalwart JMAP

Now you need to install Stalwart JMAP. To do this, navigate to the repository directory and run the following command:

cd stalwart
yarn install

This command will download and install all the dependencies for Stalwart JMAP.

Step 5: Configure Stalwart JMAP

You need to configure Stalwart JMAP to use your domain name and IP address. To do this, you will need to create a config.json file in the stalwart directory. Run the following command to create the file:

nano config.json

Add the following configuration to the file:

{
  "domains": [{
    "host": "example.com",
    "cert": "/etc/ssl/example.com/fullchain.pem",
    "key": "/etc/ssl/example.com/key.pem",
    "outboundIP": "your.ip.address.here",
    "outboundSMTP": {
      "host": "your smtp host",
      "port": 587,
      "secure": false,
      "auth": {
        "user": "your smtp user",
        "pass": "your smtp password"
      }
    }
  }]
}

Replace example.com with your domain name and your.ip.address.here with your server’s IP address. Also, replace the outboundSMTP configuration with your SMTP host, user, and password.

Step 6: Start Stalwart JMAP

Finally, you can start Stalwart JMAP. To do this, run the following command:

sudo node index.js

This command will start Stalwart JMAP and it will listen on ports 80 and 443. You may need to open ports 80 and 443 on your firewall.
