Use this in development.rb

config.action_mailer.delivery_method = :smtp

config.action_mailer.smtp_settings = {
     :address => "smtp.gmail.com",
     :port => 587,
     :user_name => "your mail",
     :password => "your password",
     :authentication => :plain,
     :enable_starttls_auto => true
}

setup mailer to send emails

in app/mailers/user_mailer.rb

class UserMailer < ActionMailer::Mailer
  default from: "no-reply@myapp.com"

def welcome(user_email)
   @user=User.find_by_email user_email
   Rails.logger.info "==========sending welcome email to ==> #{@user.email}"
   mail(:to => @user.email, :subject => "Hi #{@user.username},Welcome to #{configatron.app_name}")
end
 end

setup view file to send as email

app/views/user_emailer/welcome.html.erb

<p>Hi <%= @user.username %>,Welcome to myapp.com</p>

setup email configurations

in config/initializers/email_setup.rb

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

setup keys/passwords,using gmail..for development but use mailchimp/mandrill for pro

in config/email.yml

    development:
      :address: smtp.gmail.com
      :port: 587
      :authentication: plain
      :user_name: milind@gmail.com
      :password: password

      :port: 587
      :authentication: plain
      :user_name: milind@gmail.com

try this in your development.rb file

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
      :address => "smtp.gmail.com",
      :port => 587,
      :authentication => :plain,
      :domain => 'yourdomain.com',
      :user_name => 'your_gmail_email',
      :password => 'your_password'
  }
