How to use Google or any other SMTP server?
You can use google SMTP settings. There is demo configuration screenshot. Also I have provided some additional info below this image.
- host: tls://smtp.google.com
- port: 587
- Username: Your google email address
- Password: Your google password
If during configuraiton you get error like Authentification error, you may need to create an application password. It's security policy used by google to avoid third party applications accesing your account.
https://security.google.com/settings/security/apppasswords?pli=1 - application password can be created there

Some of the e-mails comes from root@localhost, where can I change that?
You have to edit mail templates. E.g http://demo.livehelperchat.com/site_admin/abstract/list/EmailTemplate
Edit "From e-mail" and set proper sender e-mail.
