How to send and receive mail using Mandrill?

Question

I use Ruby on Rails, could you teach me how to use Mandrill to send and receive mail.

My problem is when the user enters text and clicks submit, I want the message to be sent to my mail. I read the documentation, but I do not understand this.

This is my development.rb, the same as production.rb

ActionMailer::Base.smtp_settings = {
    :port =>           '587',
    :address =>        'smtp.mandrillapp.com',
    :user_name =>      '[e-mail]',
    :password =>       's82SlRM5dPiKL8vjrJfj4w',
    :domain =>         'heroku.com',
    :authentication => :plain
}
ActionMailer::Base.delivery_method = :smtp

user_mailer.rb:

class UserMailer < ActionMailer::Base
  default from: "[e-mail]"
  def welcome
    mail(to: "[e-mail]", subject: "Welcome", body: "Have a nice day")
  end 
end

and in the controller:

def index
  UserMailer.welcome.deliver
end

My log is as follows:

First of all you need to create an account at mandrill.com.
