## **Introduction**

[blackhole.mx](http://blackhole.mx) is a free crowdsourced service to help security professionals fight internet abuse, [spam](https://abusix.com/glossary/spam/) and [phishing](https://abusix.com/glossary/phishing/).

## \*\*Who may use \*\*[**Blackhole.mx**](http://Blackhole.mx)

Anyone may park the [MX](https://abusix.com/glossary/mail-exchanger/) records for their domain(s) to [blackhole.mx](http://blackhole.mx).

## \*\*Why point domain MX records to \*\*[**blackhole.mx**](http://blackhole.mx)

By pointing your unused domains, or domains without [MX](https://abusix.com/glossary/mail-exchanger/) records, to [blackhole.mx](http://blackhole.mx), you are allowing security professionals working at [Mailbox Providers](https://abusix.com/glossary/mailbox-providers/), Public Network Providers, and Security Companies to fight [spam](https://abusix.com/glossary/spam/) much more effectively by letting them see unsolicited email communications from their networks and thus locate infected machines and [bots](https://abusix.com/glossary/bots/).
