Sovereign email suite · in production

Your own mail server. Your own AI. Your own domain.

A self-hosted email platform in two parts: ENVOY, a mail server you run, and Chancery, an AI that drafts your replies on local models. Your correspondence is sent, received and drafted entirely on your own hardware — never handed to Google or Microsoft to read, train on or mine. It already runs the email behind this site.

ENVOY · the mail server

A sovereign mail server that won't silently fail.

A full self-hosted mail stack on your own domain — with the monitoring that keeps it from becoming the silent black hole most self-hosted mail eventually does.

Self-hosted & properly signed

A complete mail server behind a hardened public relay, sending and receiving on your domain with DKIM, SPF and DMARC — so your mail is authenticated and lands in inboxes, not spam folders.

Continuous health monitoring

A twelve-point watchdog checks every link — DNS, the relay's front door, the mail services, a real login round-trip, even blocklist status — on a schedule, with an uptime history.

Out-of-band alerting

If anything degrades, you get a push notification through a channel independent of the mail stack — because an alert about dead mail can't be sent through the mail that just died.

On your hardware, on your mesh

The server runs on your own machines over a private mesh; only a thin public relay faces the internet. Your mailboxes and data never sit on a third party's servers.

Chancery · the AI reply engine

An AI that drafts your replies — on your own models.

Chancery reads your inbox, writes the reply, and hands it to you to approve. The drafting runs on local models on your own compute — nothing is sent to a third-party AI API.

Drafts in your voice

It reads each incoming message and writes a reply as you, pinned to your identity — then presents it in a clean mail client to review, edit and send. You stay in control of every word that goes out.

Local models, model relay

Drafting runs across a relay of open models on your own hardware, picking a fast, capable model and falling back to a sovereign on-device option if a node is offline — no cloud AI dependency.

A real mail client

A three-pane interface — folders, message list, reading pane — with multi-account support, HTML email rendering and an integrated reply. The AI is a feature inside it, not the whole product.

Draft-only by design

Chancery prepares; you decide. It never sends mail on its own — it accelerates your correspondence while leaving the final say entirely with you.

How it works

From inbound mail to a reply you approve.

1
ReceiveMail arrives at your public relay, passes over a private mesh to ENVOY — DKIM-signed and spam-scored, fully under your control.
2
DraftChancery reads the message, routes it to the best-fit local model and writes a reply in your voice, grounded in prior context.
3
Approve & sendThe draft appears in your mail client. You edit if needed and send — out through your own relay, on your own domain.
4
Stay upENVOY's monitor runs continuously and alerts you out-of-band the moment any part of the chain degrades.
Live, not a concept. ENVOY and Chancery run the email for this very domain — receiving, drafting and sending in production on Collab-Foundry hardware.
