How to set up SMTP email delivery with a Gmail account
If you want to make your Rails application be capable of sending SMTP emails, check out the action mailer configuration section Archive in the Ruby on Rails guide.
TL;DR you will end up having an smtp_settings
hash that looks something like this:
Copysmtp_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:
Copy# 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:
Copysmtp_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 Archive . 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.
Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for unsupported versions of Ruby on Rails (2.3, 3.2, 4.2 and 5.2).
