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",
