About Mailez
Self-hosted email that scales from one person to a 10,000-seat organization.
Our Mission
Mailez was born from a simple observation: running your own mail server shouldn't require a Linux mail expert. We believe that teams and organizations should be able to keep their email data in their own hands, without handing it to third-party services or struggling with complex configurations.
Our goal is to make self-hosted email accessible to everyone — from small teams to large organizations — with a solution that's easy to deploy, secure by default, and actually pleasant to use.
What Makes Mailez Different
One Command Deploy
No complex setup scripts. No manual configuration. Build the images and start the whole system. That's it.
Modern Webmail
A webmail that feels like a native app. Three-pane layout, keyboard shortcuts, AI assistant, offline support. Not an afterthought — a first-class citizen.
Security by Default
Spam filtering, DKIM/DMARC, MTA-STS, DANE, PGP encryption, two-factor authentication, malware scanning. All enabled and configured by default.
One Engine
Community and Enterprise run the same in-house Mailezine single-binary engine. Both share the same Webmail and admin console with identical protocols and features — the editions differ only in storage scale and licensed features; choose by need, upgrade when you scale.
Open Source
Mailez is open source and always will be. We believe in transparency, community collaboration, and giving users the freedom to inspect, modify, and distribute the software.
The community edition is licensed under AGPL-3.0 (the GNU Affero General Public License v3.0):
- Unencumbered self-hosting — deploy, modify and run it for yourself or your organization freely
- Copyleft protection — distributing it or serving a modified version over a network requires sharing the source
- Commercial licensing available — closed-source use, SaaS/managed offerings and OEM embedding need a commercial license (included with the enterprise edition)
This keeps Mailez an open self-hosting tool that cannot be repackaged into closed, competing commercial services — while the enterprise commercial license covers friction-free business use.
