# Welcome

MXGuard is a self-hosted email validation platform that verifies emails through real SMTP checking. Install it on your own Linux server, connect your validation nodes and proxies, and run unlimited email validations independently.

## How it works

MXGuard performs MX record lookups followed by real SMTP handshakes to classify emails as **deliverable**, **undeliverable**, **risky**, **accept-all**, or **disposable**. No regex guessing — actual server-level verification.

{% hint style="info" %}
MXGuard is a one-time purchase. No monthly fees, no per-email charges, no credit limits. You own and control your entire validation infrastructure.
{% endhint %}
