Rails ActionMailer with SendGrid

Question

Hello, I'm using SendGrid to send emails on Heroku...

The problem so far is while it works great on Heroku, on my local host it fails.

Right now I have SendGrig install here, config/setup_mail.rb:

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']
}

What's a Heroku/SendGrid way to allow me to make sure my mailers work in DEV. Is this setup_mail.rb file a good thing? Should it be in the env file? Any other thoughts?

Thanks

Answer 1

Just set environment variables on your development environment for SENDGRID_USERNAME, SENDGRID_PASSWORD, and SENDGRID_DOMAIN. Then it will work.

You can get the correct values for these from your Heroku app. Open heroku console and get the values of ENV['SENDGRID_USERNAME'] and so on.

Or just use a different set of SMTP settings locally. Or use sendmail or something.

Using config/environments/[development.rb | production.rb] as tfe mentioned above sounds like its the way to go. Just put the ActionMailer configuration in either of those files and change it to suit the development|production environment.

You can also find your SendGrid credentials used by Heroku by issuing the following command:

heroku config --long

These credentials are used for all SendGrid authentication (SMTP Auth, Website login to view stats, etc., API access)
