PowerMTA SMTP Setup Training

I want to master the complete, hands-on process of building an SMTP server with PowerMTA—from provisioning the host to sending a signed, inbox-ready test message—so I can replicate the steps safely in my own lab environment whenever I need to.

Here is what I’m looking for:

• Live or well-structured recorded guidance that walks me through installation, licence activation, IP and hostname configuration, and integration with a mail client or PHP script.
• Clear explanations of SPF, DKIM, rDNS, DMARC and basic warm-up logic, so every piece makes sense rather than feeling like copy-paste commands.
• Advice on picking a suitable server provider; I haven’t settled on AWS, DigitalOcean, Vultr or a dedicated box yet and I value your recommendation on specs, IP reputation, and cost.
• A lightweight cheat-sheet or notes at the end that summarise the commands and config file edits, letting me rebuild the stack on demand.

The end goal is knowledge transfer, not just a working server. By the time we’re done I should be able to spin up a fresh VPS, install PowerMTA, secure it, add domains, and fire off compliant test emails without your intervention.

If you’ve previously deployed PowerMTA and can explain each step in plain English over Zoom, Meet, or any screen-share tool, I’d love to schedule sessions right away.
