You need a hosted email product with vendor support.
The problem it solves#
Running email infrastructure is already operationally heavy, and standard self-hosted stacks do not always match service-provider requirements. Teams may need external database support, deployment changes, or behavior that upstream Mailcow has not accepted yet.
Forking a mail stack can solve those gaps, but it also creates maintenance work. Operators need to track which changes came from the fork, which were proposed upstream, and which are still divergent.
How it solves it#
Mailcow-based email stack
Galae is built as a fork of Mailcow, so it starts from a known self-hosted email stack rather than a new mail server design.
Service-driven customizations
The README says the fork was created to implement functionality required for the Galae service launch.
Scalable stack goal
The project states a goal of building a scalable production-ready stack, including customizations such as external database work.
Upstream tracking table
The README maps Galae customizations to Mailcow issues and PRs, making divergence from upstream easier to review.
Strengths and trade-offs#
Strengths
- Practical fork documentationThe upstream issue and PR table helps operators understand why the fork exists and which changes may return to Mailcow.
- Built from a proven baseUsing Mailcow as the base gives Galae a mature email stack foundation instead of asking operators to trust a new mail system.
Trade-offs
- -Fork maintenance riskA Mailcow fork can lag or diverge from upstream, so operators must evaluate update cadence, security patch handling, and merge practices.
