You can point your domains to blackhole.mx and switch back at any time. You keep full control over your domains. We accept all kinds of domains - each additional domain helps making blackhole.mx more effective.
We do not intend to burn or spoil the reputation of domains - we use them to receive from and to respond to people sending unsolicited emails.
If you point your domain to the blackhole.mx systems, the email traffic sent to the domain will receive a 550 hard bounce response from the blackhole.mx servers, which means there is no email service currently in operation for the domain.
This will ensure the sender should take action to avoid sending spam in the future. Thus your domain can be used for a real email service later or at any time again.

yourdomain.tld. IN MX 10 void.blackhole.mx.
