Mailuminati builds open and collaborative tools for the email ecosystem.

Our focus is on spam detection, phishing mitigation, abuse handling, and large scale email security, with an emphasis on practical engineering, performance, and shared intelligence.

Mailuminati projects are open to anyone operating email services, from large providers to small operators, community infrastructures, associations, and independent administrators.

Mailuminati develops tools and systems designed for real world email infrastructure:

• Mail service providers of any size
• Self hosted and community run mail systems
• Associations and non profit infrastructures
• Abuse desks and trust & safety teams
• Anti spam and anti phishing engineers
• Researchers working on email threats and deliverability

Our projects are built to operate close to MTAs and filtering engines, under real constraints on latency, CPU usage, and storage.

We prioritize solutions that can be deployed in production, on real mail flows, without unrealistic resource requirements.

Mailuminati tools avoid raw email sharing and personal data exchange. Detection relies on structural signals, proximity, and aggregate intelligence.

Spam and phishing are industrialized. Defense must be collective.

Mailuminati promotes shared threat intelligence without centralizing content, ownership, or control.

Most of our work is open source, documented, and designed to be inspected, audited, and improved by the community.

Some of the projects hosted under the Mailuminati organization include:

• Mailuminati Guardian
  A distributed and collaborative email threat detection system based on structural fingerprinting, locality sensitive hashing, and remote confirmation.

• Mailuminati Oracle
  A shared decision engine that validates proximity signals and maintains threat clusters derived from community feedback.

• Tooling and integrations for MTAs, filtering engines, and abuse workflows.

Each repository documents its own scope, architecture, and deployment model.

Mailuminati is intended for anyone who operates, maintains, or secures email services, including:

• Large and small email providers
• Independent mail server operators
• Community and associative infrastructures
• Hosting providers
• Security researchers and practitioners

If you run mail infrastructure and care about abuse, these tools are for you.

Unless stated otherwise, Mailuminati projects are released under permissive open source licenses.

See individual repositories for license details.

Contributions, feedback, and experimentation are welcome.

You can:

• Explore the repositories
• Open issues with real world use cases
• Propose improvements or new ideas
• Share operational feedback from production environments

Mail defense works best when knowledge and signals are shared.

Email remains one of the most critical and most abused communication systems.

Mailuminati exists to help anyone operating mail services defend it collectively, pragmatically, and at scale.
