Open-source engine that gives local agents a mailbox: any IMAP/JMAP account, event log you can replay, approve/undo on every action, no model inside
Sharing because this sub cares about running things locally. The engine itself contains no model. It syncs a mailbox (IMAP, JMAP, or forwarded mail) into an ordered event log and exposes actions over HTTP, SSE, webhooks and MCP. Whatever reads it is your choice: an Ollama-backed agent, n8n, a script.
The parts I think matter for agents:
\- An agent holds a scoped token. Folders, verbs, and whether its writes execute or just get proposed for a human
\- Every action is idempotent (client keys, so a retry never sends twice) and journaled, so it can be undone
\- Trust level on every message from the DMARC result, so an agent can refuse to act on a suspicious one
\- Message content is data, never instructions. OTPs and card numbers are masked before a body leaves the engine
Apache-2.0, no CLA, one Docker container. Beta, tested on Dovecot and Stalwart only so far.
