Usermin is a web-based interface for web mail, password changing, mail filters, and much more, that seamlessly integrates with Webmin.
It is designed for use by regular non-root users, and limits them to tasks that they would be able to perform if logged in via SSH or at the console.
Most users of Usermin are sysadmins looking for a simple webmail interface. Unlike most other webmail solutions, it can be used to
- Change passwords
- Read emails with no additional servers installed (like IMAP or POP3)
- Setup users' configurations for forwarding
- Spam filtering and autoresponders.
