OS.ST Mail Admin

Web admin console for the XMail mail server: accounts, aliases, auto-replies and queue management. Adopted by our enterprise email customers.

OS.ST Mail Admin is the web console for running XMail mail servers — a modern rebuild of the classic UMPL admin tool. Accounts, aliases, auto-replies, queues and settings are all managed in the browser, and it works out of the box with an existing XMail installation. Our own enterprise email customers run on this console. Deployment is your choice: cloud, your own server, or a single PC — on Windows 11 / Server 2025, mainstream Linux (RHEL/EL, Ubuntu LTS) or macOS (Apple Silicon and Intel).
