How to send regular Global Messages via Server.Ini

Greetings everyone,

as the title said, I Need a way to Display a Global Message regularly on the Server. Is there any Way to do this? Additionally, I would like to send a Automatically generated message to Every Newly Generated Player. Thanks in Advance for the Response.

I use a tool called RustAdmin.
I can show you my configuration for it. 
You can use daly, perodicaly or just messages which are once send.
