Heroku not sending email with Gmail SMTP

Question

The app works everything, I\'m trying to use Confirmable with Devise, on my Rails app it says that the email was sent, but I never receive it. I\'m configuring it with Gmail

Answer 1

First heroku does not allow to send mails for free, you need to set up your credit card details to send mails, Secondly

Check you have rightly configured

open development.rb and update with the following

config.action_mailer.delivery_method = :smtp
  config.action_mailer.default_url_options = { host:'localhost', port: '3000' }
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.default :charset => "utf-8"
  config.action_mailer.smtp_settings = {
      :address => "smtp.gmail.com",
      :port => 25,
      :domain => 'localhost:3000',
      :user_name => "email id",
      :password => "password",
      :authentication => :plain,
      :enable_starttls_auto => true
  }
