How do I get started safely?

1. Prepare a controlled supported server, backups, DNS access and required network paths.
2. Install the WordPress plugin and choose the appropriate mode.
3. For Direct Mode, review and run the generated version-matched one-time SSH agent command with sudo.
4. Create a sender domain, publish its DNS plan and validate the public records.
5. Confirm services, sending and security before enabling permanent mail takeover or changing production MX.

A clean supported host can receive required packages through the installer. An existing supported standalone Postfix installation is backed up and requires a reviewed first apply. Do not paste server credentials or signing secrets into a support ticket.
