If you want to make your Rails application be capable of sending SMTP emails, check out the action mailer configuration section Show archive.org snapshot in the Ruby on Rails guide.
TL;DR you will end up having an smtp_settings hash that looks something like this:
smtp_settings = {
address: ...,
domain: ...,
port: ...,
user_name: ...,
password: ...,
authentication: ...,
tls: ...,
enable_starttls_auto: ...,
}
This hash can be set as the delivery_method in your environment or individually applied to an email generated in your mailer:
# production.rb:
Rails.application.configure do
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = smtp_settings
end
# test_mailer.rb
def test_mail
mail(to: 'mail@example.com', subject: 'Subject').delivery_method.settings.merge!(smtp_settings)
end
Configuring SMTP with a Google account
These is an example configuration you can use to test if mail delivery works in your application:
smtp_settings {
address: 'smtp.gmail.com',
domain: 'smtp.gmail.com',
port: 587,
user_name: 'your_email@google.com',
password: 'google_app_password',
authentication: 'login',
tls: false,
enable_starttls_auto: true,
}
If you are using Google with 2FA, you still can deliver mails
The solution for SMTP mail delivery from a google account with two factor authentication is described here Show archive.org snapshot . You basically create a password that bypasses your security efforts. So make sure that you DONT GIVE IT AWAY, Google also suggests you to not write it down, etc.
