How to use SMTP for outgoing email from CMS?

My web server doesnt have email service open. Is it possible to use SMTP for outgoing email from XiboCMS?

If you’re using docker, I believe it’s in the config.env file. If you’re using gsuite and need to use google app password, which contain spaces, or if you use non alphanumeric characters in your password put the “app password in quotations”
