title: Can't get Mandrill to send emails from Rails App
body: <p>I'm trying to send emails in a Rails app. It works if I use Gmail, but it's not working if I use Mandrill. I'm getting this timeout error with Mandrill. Not sure what I'm doing wrong. With both Gmail and Mandrill I am setting the username and password/api_key using environment variables. The only difference between the two setups is what you see below. Any ideas? </p>
