Usermin For Webmail
If you just want to use Usermin for web-based email, there is a modified package available with a better theme and default configuration for that purpose. It assumes that your system is already running a properly configured IMAP server such as Dovecot, but can be easily configured to read mail from Maildir or mbox-formatted directories instead.
Unix tar/gzip format
RPM suitable for Redhat, Fedora, CentOS, SuSE or Mandrake Linux
Debian package suitable for Debian, Ubuntu or other derived Linux
The installation processes for these packages is exactly the same as the regular package of Usermin.
