First versioned BearMail packaging release.
BearMail is a self-hosted company mailbox and calendar plus an MCP sidecar so each AI agent gets a dedicated, scoped address on your domain. It is not a Gmail replacement and not a managed suite.
Artifacts (Linux x86-64)
stalwart— mail/calendar engine used byrelease_install.sh/upgrade.shstalwart-webui.tar.gz— human WebUISHA256SUMS
The MCP sidecar is not inside the Stalwart binary. Install it with mcp_install.sh, or copy mcp/ and run npm ci --legacy-peer-deps && npm run build.
What landed for operators
- Interactive installer (name.com DNS, Brevo/Mailjet relay, Caddy HTTPS)
- WebUI for humans; JMAP store shared with agents

Limits (read these)
- Linux x86-64 + systemd only. No Docker, Kubernetes, or ARM in this release.
- DNS automation is name.com. Other registrars are manual.
- Default send mode is draft-only. Direct send is an explicit opt-in.
- Agents use a Stalwart API key (
API_…). Do not putapp_…inBEARMAIL_TOKEN. - Calendar invite success means JMAP accepted the event, not that Gmail rendered it.
