Get involved and help us fight spam
What happens with your domains if you use your domains only for http (or other services) but not for email? Blackhole.mx will help you from being spammed in the future and will be able to analyze the unwanted email traffic to fight spam efficiently.
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.
How it works
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 recipients of this domain will usually receive a 550 hard bounce code from the Blackhole.mx mail server, which means there is no email service currently in operation for the recipients.
Emails will only be accepted for some recipients if we are sure that the original sender of the email takes care and will 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.
Let us know
If you have pointed your domain(s) to the Blackhole.mx system, please let us know – so that we have the chance to immediately react and scale the system properly.
Important: If you plan to point a whole domain portfolio to our systems, it will be necessary to inform us before doing so, so that we can take the necessary steps on our side!
