If your server is connected to the internet and you disable SMTP_Auth your server will be an open Relay and will be banned by other mailservers.

If your Server is in a private network, you can change mynetworks = 127.0.0.0/8 in the main.cf to a netmask that allows your complete internal network to relay mails through this server.
