Contact Form Mailer in Rails 4

Question

I am trying to build a contact form in Rails 4, where the form takes a name, email, and body and sends it to my email address. Upon clicking "Submit", the app redirects back to the Contact page correctly, but no email appears to get sent. routes.rb ``` match '/send_mail', to: 'contact#send_mail', via: 'post' ``` contact_email.html.erb ``` <%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %> <%= javascript_include_tag "application", "data-turbolinks-track" => true %>

It turned out that I hadn't configured my Heroku app with an external SMTP service (since I have never done anything with email before, I didn't know to do this). Since I'm relatively familiar with MailChimp, and especially since their Mandrill service has a free tier (I am building this app for a student organization), I easily added Mandrill to my Heroku app and included the following settings in application.rb:

```
ActionMailer::Base.smtp_settings = {
    address: 'smtp.mandrillapp.com',
    port: 587,
    user_name: ENV['MANDRILL_USERNAME'],
    password: ENV['MANDRILL_APIKEY']
}
```

Where the ENV vars were set automatically by the add-on.
