Show HN: E2a — Open-Source Authenticated Email Gateway for AI Agents with HITL Approval — 39 Points

GitHub / Hacker News·low signal

Mnexa-AI launched E2a, an open-source email gateway giving AI agents real email addresses with SPF/DKIM verification, HMAC-signed delivery, WebSocket fan-out, and built-in human-in-the-loop approval for outbound emails before they're sent. Agents authenticate via API key, connect over WebSocket, and receive inbound mail as JSON with stable conversation threading across human and agent replies. The project solves the practical infrastructure gap of agents needing authenticated email identities without ngrok or webhook configuration.
