title: ActionMailer sending emails with empty body
body: <p>It appears that around the time that I upgraded rails to 3.2.8, the body isn't being set when I create and send emails. No code around the mailers has changed in this time, with the exception of ActionMailer also upgrading to 3.2.8.</p>
  
  <p>I have <code>beta_request_mailer.rb</code> in <code>app/mailers</code> with the following method:</p>
  
  <pre><code>def beta_request(request)
    mail(
      :to =&gt; "#{request[:name]} &lt;#{request[:email]}&gt;",
      :subject =&gt; 'Thanks for requesting an invite to xxxxx!'
    )
  end
  </code></pre>
  
  <p>I also have a body file which worked fine: <code>app/views/beta_request_mailer/beta_request_email.html.erb</code></p>
  
  <p>The email is being sent fine, just without any body. Running in the console, the mail object that's created in beta_request has no body when running <code>mail.body</code>. If I set a body manually, that gets sent out.</p>
  
  <p>What's changed that I'm not aware of?</p>
