E2a – Open-source email gateway for AI agents

About

We were building an agent system and wanted email as a trigger. We decided to take it out and made it a standalone service.The primary email features we wanted and used for our own agent system:1. Email threading stays consistent with agent conversation threading2. Human in the loop review for outbound emails (especially during testing phase)3. Quick onboarding/offboarding email addresses for agents within minutes4. Websocket for local agents and at-least-once webhook delivery for Cloud agentsNot yet: DMARC (only SPF/DKIM today), scoped API keys, HA/multi-region (single VM + single Postgres), app-layer email data encryption, compliance attestations (SOC 2/HIPAA).GitHub: https://github.com/Mnexa-AI/e2aHosted: https://e2a.dev/Appreciate any feedback / contributions.
