Heroku/Rails App Error

Question

I'm really stuck here and am worried my mailer config files are all messed up. My app seems to work fine locally, I'm on Nitrous. I can git push heroku master fine and when opened can view the home page, which is just a form(https://nameless-taiga-1654.herokuapp.com/), however once I hit submit I get an error message. I believe all my mailer actions on nitrous are setup correctly, I was planning on using sendgrid via heroku to run the mailing side of things. Basically I'm just lost and need help. Attached are the heroku logs of the form error.

check your `config.action_mailer.smtp_settings ` for production. — alexsmn, Aug 08 '15 at 07:09
@alexsmn I've just copied the settings file into the original question. I really am lost here, so frustrating! — RuNpiXelruN, Aug 08 '15 at 07:45
have you tried using `mail gem`? Have a look here: https://devcenter.heroku.com/articles/sendgrid#ruby-rails — alexsmn, Aug 08 '15 at 08:04

I have had the same problem working with my current project. Actually, as I found out, this is a Gmail authentication problem. Your app is trying to login into Gmail account and cannot do it because Gmail does not see or recognize encrypted email and password. I temporarily solved this problem by writing necessary values into my smtp_settings directly, like:

    smtp_settings = {
      ...
      :user_name => "...your gmail email...",
      :password => "...your gmail password...",
      ...
    }

Also, I changed Gmail account security settings: turned off double authentication and allowed my account to be accessed by less secure apps. So, currently the app is deployed on Heroku and working. However, from cyber security point of view my solution is rather dangerous, so I am still looking for better ones.

EDITED!!! There is a better way to encrypt gmail account settings. In my .bashrc file (is hidden in computer root directory - press Ctrl+H to reveal) I wrote the following lines of code:

    export GMAIL_NAME=necessary value here
    export GMAIL_PASSWORD=necessary value here

After this I also changed my smtp_settings one more time, like:

    smtp_settings = {
      ...
      user_name: ENV['GMAIL_NAME'],
      password: ENV['GMAIL_PASSWORD'],
      ...
    }

Finally, I configured repo setting on Heroku: Heroku/Personal apps/myApp/Settings, section "Config variables" via adding two new variables GMAIL_NAME and GMAIL_PASSWORD with necessary values.

It worked.

Try setting the following in your production.rb file:

config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.default_url_options = { host: 'nameless-taiga-1654.herokuapp.com' }

Also, to verify the configuration is correct, you can run heroku config.
