UAI Mail (Product Overview)
Canonical UAI Mail identity, LEGACY aliases (umail/UR-Mail/Mailu), and AI-agent-first purpose.
Body
UAI Mail
Canonical Name
UAI Mail is the canonical product name for United AI's self-hosted email platform. Runtime authority is the Mailu container stack on host mail.united-ai.ca, serving the @united-ai.ca mail domain.
LEGACY WARNING — Alias Drift. These names all refer to the same product lane. Do not treat them as separate systems:
| Alias | Where it appears | Treatment |
|---|---|---|
| umail | Cadence env prefix CADENCE_UMAIL_*, tool id, historical Caddy comment |
LEGACY product alias |
| UR-Mail / urmail | Cadence error strings, DNS label, legacy Qdrant collection name | LEGACY branding |
| United-AI Mail | Mailu SITENAME branding |
LEGACY display string |
| Beacon route/host label on the VPS hostname | Host label only — not a separate mail app | |
| Mailu | Upstream compose stack (ghcr.io/mailu/*:2.0) |
Runtime implementation |
Always write UAI Mail in new docs. Mention LEGACY aliases only when mapping old receipts or env keys.
Purpose (AI-agent-first)
UAI Mail provides mailboxes and controlled programmatic send for humans and agents:
- Human inboxes (localparts include
scott,weekendwow, andcadence) - Agent-linked mailboxes (localparts include
scribe,skip,sunshine,midnight,noreply) - System addresses for automated workflows
Agents must not receive raw mailbox passwords, mailu.env values, or SMTP secrets. Send is mediated by Cadence approved-send tooling (see uai-doc-plans-uai-mail-ai-access and uai-doc-ecosystem-product-cadence-v6).

Capability Map Note
GET /api/ai/capability-map has no UAI Mail / umail card as of 2026-07-03. Cadence service cards exist. Beacon edge lists https://mail.united-ai.ca as its public endpoint — that is the VPS hostname, not a live mail stack. Agents must not claim live mail access until a capability card exists and the owner starts the stack.
