1 Download & Run the Script

The script installs Docker, clones the Mailcow repo, generates the configuration file with your domain, and starts the full mail server stack (20+ containers).

In the admin panel, add your domain, configure DNS records (MX, SPF, DKIM, DMARC) as shown in the UI, then create mailboxes for your users.
