IP blacklisting admins can trust.

This blacklist is fundamentally different, because you will be able to create, maintain and control it yourself. It's all in your hands.

We have been running this system for over 8 years as freelance admins and decided to make it a public product because it provides such valuable services for us.

Fine grained Blacklisting

  • We don't like global blacklists which harm admins.
  • Define the blacklist by your own down to server IP level.
  • Block whole networks like 192.168.0.0/24 to stop spammy providers.
  • See incoming mail traffic and decide based on data.
  • Organize it your way. It's all in your control!

Whitelist valuable resources

  • Whitelist IPs which are valuable to you.
  • Whitelist services which are important to your users and customers like Gmail, Mailchimp, etc.
  • Whitelisted IP-Ranges like 192.168.178.0/24.
  • Whitelisted IPs will never be blacklisted!
