问题
I just launched my rails app with heroku (http://fast-reaches-9399.herokuapp.com/). I want people to be able to type stuff in the textarea on the top, and then click the submit button, and then have it email me what is in the textarea. I'm really having trouble with it though. It redirects in the development environment, but doesn't seem to send an email. And I get a 500 error in production. Here's some relevant code...
application_controller.rb
class ApplicationController < ActionController::Base
protect_from_forgery
def email
UserMailer.idea_bar(params[:message]).deliver
redirect_to "/" # how can I redirect to the page the user was just on?
end
end
/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
default from: "anonymous@collegeanswers.com", to: "info@collegeanswerz.com", subject: "collegeanswers"
def idea_bar(message)
mail(:body => message)
end
end
application.html.erb (layout file)
<div class="idea_bar">
<div class="left_idea_bar">
<p>Ideas, comments, questions, suggestions? Help us help you!</p>
<%= form_tag("/application_controller/email", :method => "post", :id => "idea_bar_form") do %>
<%= text_area_tag('message', nil, :size => "60x4", :id => "message", :name => "message") %> <br />
<%= label_tag(:email, "• include your email if you want a response:") %>
<%= text_field_tag(:email, nil, :id => "email", :size => "36") %>
</div>
<button id="submit" type="submit" form="idea_bar_form"><span id="big_submit">Send</span>
<span id="small_submit"><br />• one click<br />• anonymous</span></button>
<% end %>
</div>
/user_mailer/idea_bar.html.erb (test file. I want the email to be what's in the textarea, not this)
<html>
<head></head>
<body>
<p>hello</p>
</body>
</html>
/user_mailer/idea_bar.text.erb

You're likely seeing the connection refused error because you're not being allowed to connect to the local SMTP server on Heroku, which is not allowed.
You'll need to use an external SMTP service. Heroku has plug-ins for several providers which offer external SMTP service listed on their addons page: (https://addons.heroku.com/#email-sms). Each add-on provides instructions on how to configure your application
You could also use a standard mail service for which you have an account and configure it through ActionMailer. You can try something like this in your config/environments/production.rb if you have a GMail account.

From log supplied it's clear that you get an error because Rails ActionMailer is unable to connect to SMTP server. To debug this problem in production you can change config in development.rb to this:
config.action_mailer.raise_delivery_errors = true
so you will see mailer exceptions in development. When you have exact error msg you can update log in question for further help.
