Configuring Gmail SMTP with Actionmailer

2010-03-30

Just a couple of reminders for myself, in case I spend wasted time trying to get gmail smtp working on actionmailer again.

To get your ActionMailer configured for gmail:

# in config/environments.rb # add the following lines AFTER your Rails::Initializer.run block

email_settings = YAML::load(File.open("#{RAILS_ROOT}/config/email.yml"))

ActionMailer::Base.raise_delivery_errors = true ActionMailer::Base.perform_deliveries = true ActionMailer::Base.delivery_method = :smtp ActionMailer::Base.smtp_settings = email_settings[RAILS_ENV] unless email_settings[RAILS_ENV].nil?


in config/email.yml (if its not there, create it)
add the following for each rails environment
development:
  :enable_starttls_auto: true
  :address: smtp.gmail.com
  :port: 587
  :authentication: :plain
  :user_name: <[email protected]>
  :password: <password>
  :domain: gmail.com
remember the extra ‘:’ before the yaml key. This is what wasted my time

And magic.

There’s no need to install any new smtp/tls libraries as there’s already built in support for tls authentication within ActionMailer. Just make sure to set ‘enable_starttls_auto’ to true.
