• AWS_SES_RECVR - Email address to send generated emails to [optional, default: info@dynamicgravitysystems.com]

Example NGINX Config

upstream sendmail {
    server localhost:8080;
}

server {

    listen 443 ssl;
    # Do ssl configuration here
    # Or let certbot generate it
    
    server_name api.dynamicgravitysystems.com;
    
    location /sendmail {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_pass http://sendmail;
    }
}

Add the above configuration to an existing server block, or new config file in /etc/nginx/sites-available then add a symlink (ln -s /etc/nginx/sites-available/{config-file} /etc/nginx/sites-enabled/) as necessary. Note: On RHEL/CentOS the NGINX directories are different, typically there is just a /etc/nginx/conf.d directory which holds all enabled configurations.

After updating NGINX config execute the following to test and reload:

nginx -t
sudo nginx -s reload
