In this tutorial, we will show you how to install Usermin on Debian 12. Usermin is a robust tool that empowers non-root users to perform a variety of tasks on Unix systems. It’s a boon for system administrators who require a straightforward webmail interface for their customers. Unlike many other webmail solutions, Usermin doesn’t necessitate additional servers like IMAP or POP3 for reading emails. It also allows users to change passwords and set up configurations for forwarding, spam filtering, and auto-responders.
Usermin stands out from similar tools like Webmin and Virtualmin due to its focus on non-root users. While Webmin and Virtualmin are more oriented towards system-wide administration and virtual hosting management respectively, Usermin is designed to simplify tasks for regular users, making it a unique and valuable tool in the Unix ecosystem.

For enhanced security, it’s recommended to change the default Usermin port from 20000 to a less predictable number. This can deter potential attackers who might target the default port. After making these changes, restart Usermin to apply them.
