email is sent but does not reach to mailbox using devise method "confirmable" for confirming user by email

Question

I am implementing devise "confirmable" method to confirm user by sending email for ruby on rails App. My app "development.log" file shows that email has been sent but it does not reach on destination. Following are my files containing code:-

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
  attr_accessible :title, :body
  def password_match?
    self.errors[:password] << 'must be provided' if password.blank?
    self.errors[:password] << 'and confirmation do not match' if password != password_confirmation
    password == password_confirmation and !password.blank?
  end
end

confirmations_controller.rb

class ConfirmationsController < Devise::ConfirmationsController
  def show
    @user = User.find_by_confirmation_token(params[:confirmation_token])
  end
ef confirm_user
    @user = User.find_by_confirmation_token(params[:user][:confirmation_token])
    if @user.update_attributes(params[:user]) and @user.password_match?
      @user = User.confirm_by_token(@user.confirmation_token)
      set_flash_message :notice, :confirmed
      sign_in_and_redirect("user", @user)
    else
      render :show
    end
  end

sign up page

<h2>Sign up</h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <div><%= f.label :email %><br />
  <%= f.email_field :email, :autofocus => true %></div>



  <div><%= f.submit "Sign up" %></div>
<% end %>

<%= render "devise/shared/links" %>

development.rb

Gt::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {:address => "localhost", :port => 1025}

  # Log error messages when you accidentally call methods on nil.
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  ActionMailer::Base.delivery_method = :smtp
  ActionMailer::Base.smtp_settings = {
   :tls => true,
   :address => "smtp.gmail.com",
   :port => 587,
   :domain => "gmail.com",
   :authentication => :login,
   :user_name => "[username]",
   :password => "[password]"
 }

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

  # Only use best-standards-support built into browsers
  config.action_dispatch.best_standards_support = :builtin

  # Raise exception on mass assignment protection for Active Record models
  config.active_record.mass_assignment_sanitizer = :strict

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  config.active_record.auto_explain_threshold_in_seconds = 0.5

  # Do not compress assets
  config.assets.compress = false

  # Expands the lines which load the assets
  config.assets.debug = true
end

Answer 1

I also had this problem but got it solved by doing the following trick.

The solution is to create an initialiser in config/initialisers/setup_mail.rb containing the following

if Rails.env != 'test'
email_settings = YAML::load(File.open("#{Rails.root.to_s}/config/email.yml"))
ActionMailer::Base.smtp_settings = email_settings[Rails.env] unless email_settings[Rails.env].nil?
end

then add config/email.yml containing the details of the dev and production email accounts

development:
:address: smtp.gmail.com
:port: 587
:authentication: plain
:user_name: xxx
:password: yyy

production:
:address: smtp.gmail.com
:port: 587
:authentication: plain
:user_name: xxx
:password: yyy

Answer 2

you need to set up a default host and mailer setting in config/application.rb file.
