Problem while using ActionMailer with rails 1.1.6

Hi, all

I am new to rails. While I tried to send email by configuring the email sending than my application could not started.

My environment.rb is as follows :

# Be sure to restart your web server when you modify this file.

# Uncomment below to force Rails into production mode when # you don't control web/app server and can't set it the proper way # ENV['RAILS_ENV'] ||= 'production'

# Specifies gem version of Rails to use when vendor/rails is not present RAILS_GEM_VERSION = '1.1.6'

# Bootstrap the Rails environment, frameworks, and default configuration require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|

ActionMailer::Base.delivery_method = :sendmail

require '0-13-1_cti_instantiation_patch'

  # Settings in config/environments/* take precedence those specified here

  # Skip frameworks you're not going to use (only works if using vendor/rails)   # config.frameworks -= [ :action_web_service, :action_mailer ]

  # Add additional load paths for your own custom dirs   # config.load_paths += %W( #{RAILS_ROOT}/extras )

  # Force all environments to use the same logger level   # (by default production uses :info, the others :debug)   # config.log_level = :debug

  # Use the database for sessions instead of the file system   # (create the session table with 'rake db:sessions:create')   # config.action_controller.session_store = :active_record_store

  # Use SQL instead of Active Record's schema dumper when creating the test database.   # This is necessary if your schema can't be completely dumped by the schema dumper,   # like if you have constraints or database-specific column types   # config.active_record.schema_format = :sql

  # Activate observers that should always be running   # config.active_record.observers = :cacher, :garbage_collector

  # Make Active Record use UTC-base instead of local time   # config.active_record.default_timezone = :utc

  # See Rails::Configuration for more options end

# Add new inflection rules using the following format # (all these examples are active by default): # Inflector.inflections do |inflect| # inflect.plural /^(ox)$/i, '\1en' # inflect.singular /^(ox)en/i, '\1' # inflect.irregular 'person', 'people' # inflect.uncountable %w( fish sheep ) # end

# Include your application configuration below

ActionMailer::Base.smtp_settings = {   :address => "smtp.host.com",   :port => 465,   :user_name => "admin@host.com",   :password => "pass",   :authentication => :login }

when i write to run application on console : ruby script/server

Got the message on console and application could not started.

Pls, help me as soon as possible. Thanks in advance.
