Configure Rails action_mailer on c9



I’m having some trouble getting action_mailer configured correctly on c9. I have a feeling it’s due to improper setting in my development.rb file for action mailer.

I’m attempting to use:

config.action_mailer.default_url_options = { :host => “” }

I’m not getting any errors in my application, but mail never arrives either.
