Gmail
You can use Gmail with gcourier by simply inputting your credentials. If you have two-factor authentication enabled, you’ll need to generate an app-specific password by navigating to this page. Make sure to save the password. It won’t be visible again!
Then, you can send emails as follows:
let email = "me@gmail.com" // or me@outlook.com, me@yahoo.com
let password = "APP_SPECIFIC_PASSWORD"
smtp.send("smtp.gmail.com", 587, Some(#(email, password)), msg)
