Sendgrid connection refused

I am developing a Ruby on Rails 3.2 application on Heroku. I added the sendgrid addon with

heroku addons:add sendgrid:starter

and then restarted with

heroku restart

However, if I try to send a password email in my application (I am using the devise login gem), I get this in the logs

2013-01-24T17:35:37+00:00 app[web.1]: Started POST "/users/password" for xxx.xxx.xxx.xx at 2013-01-24 17:35:37 +0000

You need to configure ActiveMailer with something like 

ActionMailer::Base.smtp_settings = {
  :address        => "smtp.sendgrid.net",
  :port           => "25",
  :authentication => :plain,
  :user_name      => ENV['SENDGRID_USERNAME'],
  :password       => ENV['SENDGRID_PASSWORD'],
  :domain         => ENV['SENDGRID_DOMAIN']
}

and make sure your application has the SENGRID configuration variables in the environment - you can check with heroku config.
