who it's for

Who Twake Mail is for#

Self-hosted workplace email evaluation

Use Twake Mail when evaluating open source email infrastructure for a workplace suite with privacy and collaboration requirements.

JMAP client and server deployments

Use it when you want a JMAP-oriented mail stack with an official Flutter client and server-side Twake Mail features.

the problem

The problem it solves#

Teams that want private workplace email need more than a webmail skin. They need a server they can operate, a modern client path, and collaboration features such as shared mailboxes and labels without handing every mailbox to a proprietary provider.

how Twake Mail solves it

How it solves it#

Apache James-based backend

The backend adapts Apache James for Twake Mail and adds server features needed for collaborative workplace email.

JMAP client companion

The official tmail-flutter repository provides the mobile and web client layer that connects to a JMAP server.

Collaborative mail features

The backend README lists encrypted mailboxes, team mailboxes, filtering, forwarding, labels, contacts autocomplete, and push subscriptions.

strengths · trade-offs

Strengths and trade-offs#

Strengths

  • Product-owned repositoriesThe Twake Workplace README links tmail-backend and tmail-flutter as the official Twake Mail server and client repositories under LINAGORA.
  • Clear AGPL evidenceGitHub reports AGPL-3.0 for both the backend and Flutter client, and both repositories expose root LICENSE files.

Trade-offs

  • -Multi-repo product scopeThe current OSA item model stores one primary GitHub repo, so the listing uses backend telemetry and marks coverage ambiguous instead of implying full client and server coverage.
  • -Operational email complexityTeams still need to operate mail infrastructure and understand JMAP, Apache James, and deployment-specific dependencies.
versus alternatives

Twake Mail vs alternatives#

Primary repo: https://github.com/linagora/tmail-backend Companion client repo: https://github.com/linagora/tmail-flutter Coverage note: backend-primary telemetry is ambiguous for the full client/server product.

frequently asked

FAQ#

Why is repository coverage marked ambiguous?

Twake Mail is split across tmail-backend for the server and tmail-flutter for the client, while OSA can store only one primary GitHub repo for telemetry.

Which repo is the primary GitHub repo?

The listing uses tmail-backend as the primary repo because it contains the Twake Mail server work and Apache James extensions.

Does Twake Mail have an official client repo?

Yes. LINAGORA maintains tmail-flutter as the official Flutter client for Twake Mail mobile and web users.
