Ratuus is using jQuery and Smarty to provide rich interface to it's users. Together with simple and modern template design, created with user friendliness in mind, it is certain to provide intuitive user experience.
Ratuus contains ACL system with three levels of privileges providing powerful and flexible way to separete privileged users from regular users. Privileged user can have privileges under one or more domains, or superuser privileges for all domains on your mail server.
Ratuus is fully compatible with PostifxAdmin database layout. All you need to do to migrate from PostfixAdmin to Ratuus is to run simple, nondestructive installation process. The beauty of Ratuus installer is that it doesn't do any modification in your database layout, which means you can still use PostixAdmin while testing Ratuus on the same database.
