Looking for tips for those system functions


I am new to Yii, and I am looking for the following functions to build my app, I am not sure can I find it in the extensions section or here in the forum or ideas:

Scheduling & email notification solutions.

Manage configuration files for linux box using FORMS.

Manage contacts & grouping.

Files explorer, such as delete, rename …etc.

Local mail messaging between users.

System authentication based on roles.

Thank you. I highly appreciated your time and advices.

some of the feature you requested can be found on some extensions (there are several who use rbac, one is actually named rbac XD) but just keep in mind that this is a framework, so you might have to develop something at some point :P

if everything you wanted was just a bunch of thing to install on top of each other a CMS might suit your needs better.
