Welcome to my step-by-step guide on how to set up your own Mailcow mail server on a VPS!
In this video, I’ll walk you through the Mailcow installation using Docker and NGINX as a reverse proxy, show you how to configure DNS records (SPF, DKIM, DMARC), and secure your server with a wildcard SSL certificate via Cloudflare and Certbot.
💡 While many say running your own mail server is a bad idea — I show you how to do it the right way: secure, reliable, and self-hosted.
