ActionMailer : Not able to send out mails

Hello,

I have the following code in my environment/development.rb

  config.action_mailer.raise_delivery_errors = true;   config.action_mailer.delivery_method = :smtp;   config.action_mailer.smtp_settings = {

  :address => "smtp.gmail.com",   :port => 587,   :user_name => "my_id@gmail.com",   :password => "secret",   :authentication => :plain,   :enable_starttls_auto => true,   :domain => "localhost",   }

An email is being generated by the call to the mailer model from one of my controllers. However, i am not able to send or receive any emails on gmail.

I am on ruby 1.8.7, rails 2.3.5. There are no exceptions, just that no emails are being exchanged between the actual mail servers.

Being quite new to mailer, sorry for any rookie questions.

Thanks, RORails
