The score comes from our model.

• Show HN: Groundhog – local email catcher that also emulates provider HTTP APIs · score 7.8

  Groundhog is a local email catcher that emulates SMTP and the HTTP send APIs of multiple email providers (SendGrid, Postmark, Mailgun, Resend, Amazon SES) so developers can test email sending without real credentials. It includes a web inbox, failure simulation, webhook simulation, and testing helpers, making it a comprehensive tool for development and automated testing.

• Show HN: InBox Wall – A local-first, open-source email sanitizer for AI agents · score 7.5

  InBox Wall is a local-first sanitizer that cleans email HTML before feeding it to AI assistants, protecting against hidden text and prompt injection attacks. It combines CSS inlining, inheritance-aware parsing, Unicode normalization, and a fail-closed architecture, then serves safe text via a REST API and MCP server for AI consumption. The project stands out for its thorough threat model, audit dashboard, and privacy-focused design.

• Show HN: Nuvrail – make an AI agent ask before it sends, moves or deletes email · score 7.3

  Nuvrail is a self-hosted approval gateway that sits between AI agents and email servers, intercepting IMAP/SMTP writes (sends, moves, deletes) and staging them for one-tap human approval while reads pass through instantly. It's an interesting 'human-in-the-loop' security layer that requires no agent changes, using an asyncio IMAP state machine, SMTP interception, and a PWA for approvals. The concept addresses a real safety gap for LLM email agents.

• Show HN: Mailbox Viewer – publish FOIA email dumps as a static Gmail-like site · score 7.3

  Mailbox Viewer converts mbox/PST email archives into a static, Gmail-like website powered by DuckDB-WASM and Parquet files, with full-text search, attachment search, and in-browser semantic search. It's interesting because it targets FOIA/public-records dumps—making obscure email exports browsable, searchable, and shareable with zero server infrastructure.
