ActionMailer : Not able to send out mails


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 => “”,
:port => 587,
:user_name => “[email protected]”,
: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.
