Configuring Gmail SMTP with Actionmailer

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 block   email_settings = YAML::load("#{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:   :port: 587   :authentication: :plain   :user_name: <[email protected]>   :password: <password>   :domain: # 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.
