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
mail 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, and cadence)
  • 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.
