This is configurable in the config/environments/*.rb files.

# output to tmp/mails directory
config.action_mailer.delivery_method = :file

# config.action_mailer.file_settings = { :location => Rails.root.join('tmp/mail') }

Detailed information can be found in the config section of Action Mailer Basics or on ActionMailer::Base API
