Enterprise Edition
MXHook's enterprise features are licensed under the Business Source License 1.1 (BSL 1.1). The license converts to Apache 2.0 automatically after 2 years, at which point the features become fully open source.
What's Included
The enterprise edition adds advanced routing capabilities on top of the open-source core:
- Regex recipient patterns — match recipients with full regular expressions
- Header-based conditions — route emails based on header values
These features are designed for organizations with complex email routing requirements that go beyond simple pattern matching.
Licensing
| Edition | License | Features |
|---|---|---|
| Core | Apache 2.0 | SMTP, parsing, exact/wildcard/plus routing, webhooks, DLQ, replay, API, CLI |
| Enterprise | BSL 1.1 → Apache 2.0 | Core + regex patterns, header conditions |
The BSL 1.1 license allows you to use the enterprise features freely for internal purposes. The license restricts offering MXHook as a hosted service to third parties. After 2 years, the code converts to Apache 2.0 with no restrictions.
Enabling Enterprise Features
Enterprise features are included in the same binary. They activate when you create routes with regex patterns or header conditions. No separate installation or license key is required.
