I am trying to understand how to properly configure Action Mailer for Rails 3 to work with Gmail. Read the article by Ryan Bates and also read the edge Rails page article. Ryan's article said to put the config details in /config/initializers/setup_mail.rb initializer file
ActionMailer::Base.smtp_settings = { :address => "smtp.gmail.com", :port => 587, :domain => "asciicasts.com", :user_name => "asciicasts", :password => "secret", :authentication => "plain", :enable_starttls_auto => true } But the edge Rails article said put it in the config/environments/$RAILS_ENV.rb, anyone know which is the preferred way of doing it?
