title: Rails with Heroku not sending Mandrill emails
body: <p>I am starting a rails app and would like to use Mandrill to confirm Devise sign up and for other features in the future. Yesterday it was working sometimes on local so I thought maybe I would try on Heroku.</p>
  
  <p>When using Heroku's Mandrill add-on it works, but if I change the ENV credentials to my own Mandrill account the emails get backlogged on my own account.</p>
  
  <p>I am testing it using two personal emails, gmail and a school one.</p>
  
  <p>I also use figaro to copy my environment variables to Heroku.</p>
  
  <p><strong>production.rb:</strong></p>
  
  <pre><code>config.action_mailer.smtp_settings = {
  :address   =&gt; "smtp.mandrillapp.com",
  :port      =&gt; 587,
  :user_name =&gt; ENV["MANDRILL_USERNAME"],
  :password  =&gt; ENV["MANDRILL_APIKEY"]
  }
  
  # ActionMailer Config
  config.action_mailer.default_url_options = { :host =&gt; 'herokuapp.com' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = false
  </code></pre>
  
  <p><strong>development.rb:</strong></p>
  
  <pre><code>config.action_mailer.smtp_settings = {
  :address   =&gt; "smtp.mandrillapp.com",
  :port      =&gt; 2525, # I also tried ports 25 and 587
  :user_name =&gt; ENV["MANDRILL_USERNAME"],
  :password  =&gt; ENV["MANDRILL_APIKEY"]
  }
  
  # ActionMailer Config
  config.action_mailer.default_url_options = { :host =&gt; 'localhost:3000' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  </code></pre>
  
  <p><strong>application.yml:</strong></p>
  
  <p>(I copied the actual username and API key.)</p>
  
  <pre><code>MANDRILL_USERNAME: myemail@gmail.com
  MANDRILL_APIKEY: ######################
  ADMIN_NAME: First User
  ADMIN_EMAIL: user@example.com
  ADMIN_PASSWORD: changeme 
  ROLES: [admin, user, VIP]
  </code></pre>
  
  <p>The <code>username</code> for Mandrill Heroku provides me with is <code>something@heroku.com</code>.</p>
