Rails - Can't send email on production using mailgun

I have an app deployed in heroku, mails are sent successfully only in development but not in production. I'm using mailgun. Here are the error results:

Exception

     :port                 => ENV['MAILGUN_SMTP_PORT'],

     :password             => ENV['MAILGUN_SMTP_PASSWORD'],
     :authentication       => 'plain'
   }

  config.action_mailer.default_url_options = { :host => 'https://myapp.herokuapp.com/' }
  config.action_mailer.asset_host = 'https://myapp.herokuapp.com/'
  config.action_controller.asset_host = 'https://myapp.herokuapp.com/'

Alright, I didn't notice that I am using just 'mailgun.org' instead of 'smtp.mailgun.org' for the address. I changed the address value to ENV['MAILGUN_SMTP_SERVER'] and then it's working properly in production.
