Mailuminati Guardian
Collaborative & scalable spam/phishing detection
What it does
Stop Polymorphic Phishing with Structural DNA Matching 🛡️ Filters fail when attackers tweak content to bypass signatures. Guardian fingerprints the email's "DNA" using TLSH (Fuzzy Hashing). If a campaign changes a few letters, the DNA stays the same, enabling instant detection. Why it stands out: • Agnostic: Sidecar API for Rspamd, SpamAssassin, Postfix • Collaborative: Share threat clusters, not raw mail • Feedback Loop: Real-time learning via Dovecot/Sieve • Go-powered: Ultra-low latency
Does the same job

- VTVaultSandbox – Test your real MailGun/SES/etc. integrationJan 2026 · vaultsandbox.com · ▲58
I've spent the last few months working on something I wish I'd had years ago. I kept running into the same issue: CI green, production mail broken. TLS handshake failures, DKIM alignment mismatches, SPF soft-fails ... the stuff that only surfaces when real mail servers are involved. Most test tools (Mailpit, MailHog) are catch-alls. They confirm "an email was sent" but don't validate the protocol. They also aren't designed for network-exposed environments: no auth, unprotected Web UI, easy to enumerate messages. VaultSandbox is my attempt at fixing that. It's a self-hosted SMTP gateway…

- PSPII-Shield – Log Sanitization Sidecar with JSON Integrity (Go, Entropy)Feb 2026 · github.com · ▲20
What PII-Shield does: It's a K8s sidecar (or CLI tool) that pipes application logs, detects secrets using Shannon entropy (catching unknown keys like "sk-live-..." without predefined patterns), and redacts them deterministically using HMAC. Why deterministic? So that "pass123" always hashes to the same "[HIDDEN:a1b2c]", allowing QA/Devs to correlate errors without seeing the raw data. Key features: 1. JSON Integrity: It parses JSON, sanitizes values, and rebuilds it. It guarantees valid JSON output for your SIEM (ELK/Datadog). 2. Entropy Detection: Uses context-aware entropy…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
