Rails 4 ActionMailer Issue

Question

I have created a rails app for booking cabs online. I want my app to have the functionality of sending emails to users once their booking is confirmed. For this, I am following Ryan Bates railscasts:

https://www.youtube.com/watch?v=v1KI571TdUQ

I started with creating a setup_mail.rb file in app/config/initializers, with the following content:

ActionMailer::Base.smtp_settings = {
  :address              => "smtp.gmail.com",
  :port                 => 587,
  :domain               => "railscasts.com",
  :user_name            => "taxibol",
  :password             => "secret",
  :authentication       => "plain",
  :enable_starttls_auto => true
}

I then generated a mailer named user_mailer and included the following in app/mailers/user_mailer.rb:

class UserMailer < ActionMailer::Base
    default :from => "[email protected]"
  def registration_confirmation(user)
    mail(:to => user.email, :subject => "Registered")
  end
end

and the following in app/views/user_mailer/registration_confirmation.text.erb:

Welcome to example.com!
===============================================

You have successfully signed up to taxibol.in.

Thanks for joining and have a great day!

Finally, in my static_pages_controller.rb, I included the following:

class StaticPagesController < ApplicationController
    def booking_confirmation
        UserMailer.registration_confirmation(current_user).deliver
    end
end

I tested this in my localhost env, and it seems to have worked. Following is the relevant section in

Started GET "/booking/confirmation" for 127.0.0.1 at 2014-12-13 08:30:14 -0800

However, I checked my gmail account ([email protected]), but I didn't receive any mail. What could be the reason?

Update:

Instead of creating the setup_mail.rb file, I tried to include the following in config/environments/development.rb:

config.action_mailer.raise_delivery_errors = true
  config.action_mailer.default_url_options = {host: 'localhost', port: 3000}

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address: "smtp.gmail.com",
    port: "587",
    domain: "gmail.com"
    authentication: "plain",
    enable_starttls_auto: true,
    user_name: "[email protected]"
    password: "some_password"
  }

Again got the same log trails, but no mail yet :(

Tried that as well Nitin...but no result :( BTW...what should go into domain? Any idea? — Rahul Poddar
domain is right, change default :from address and give a try.. — Nithin
D-side: I tried with mailcatcher and it works. So the problem seems to be in the SMTP settings. Can someone point where am I going wrong in the SMTP settings? Thanks in advance! — Rahul Poddar

I am not sure if you tried keeping :user_name with full domain extension. So it should be something like this:

ActionMailer::Base.smtp_settings = {
 :address              => "smtp.gmail.com",
 :port                 => 587,
 :domain               => "railscasts.com",
 :user_name            => "[email protected]",
 :password             => "secret",
 :authentication       => "plain",
 :enable_starttls_auto => true
}

Also Google Apps has per day 100 email limit. Check if you have already exhausted that limit which might be causing this.
