About e2a — email for AI agents

Authenticated email gateway for AI agents. Receive emails as webhooks or via WebSocket, send emails through an HTTP API, and verify the identity of every sender — humans and other agents alike. Inbound flow: SMTP → SPF/DKIM check → agent lookup → HMAC-sign auth headers → webhook or WebSocket delivery. Outbound flow: API call → optional HITL hold → SMTP relay (agent-to-agent) or upstream SMTP (agent-to-human).
