[Mandrill](http://mandrill.com/) SMTP API integration for ActionMailer.
See detail of the protocol on [the official page](http://help.mandrill.com/entries/21688056-Using-SMTP-Headers-to-customize-your-messages).

## Installation

Add the mandriller gem to your Gemfile.

```ruby
gem "mandriller"
```

And run `bundle install`.

Add the following into any environment's settings in `config/environments/`.

```ruby
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  :user_name => 'UserName',
  :password => 'Password',
  :address => "smtp.mandrillapp.com",
  :domain => "your-domain.com",
  :enable_starttls_auto => true,
  :authentication => 'login',
  :port => 587,
}
```

## Usage

e.g.

```ruby
class UserMailer < Mandriller::Base
  include AbstractController::Callbacks # To use before_filter in ActionMailer::Base

  set_open_track
  set_click_track
  set_google_analytics [Settings.root_host, Settings.admin.host].uniq

  before_filter do
    set_google_analytics_campaign "#{mailer_name.gsub(/_mailer$/, '')}/#{action_name.gsub(/_email$/, '')}"
  end

  def test_mail
    mail from: 'from@example.com', to: 'to@example.com'
  end
end
```
