help debugging ActionMailer with restful_authentication?

In a nutshell, I'm using restful_authentication that emails the user when they sign up for an account

The development.log file shows the body of the e-mail message being prepped to send out, but doesn't show confirmation that it made it.

When I use gmail's SMTP server, a Rails exception is thrown because gmail expects an encrypted connection. A different type of Rails exception is thrown if I try to connect to a Windows SMTP server on my local machine. I used Yahoo's SMTP server and no Rails exceptions is thrown. So, I have a feeling that a connection is made to the Yahoo SMTP server but, for some reason, no email is delivered.

Could someone advise on how to debug this and find out why it's not being delivered?

Here's the setup code in environment.rb ActionMailer::Base.delivery_method = :smtp ActionMailer::Base.raise_delivery_errors = true

  ActionMailer::Base.smtp_settings = { :address => "smtp.mail.yahoo.com" , :port => 25, :domain => "www.haloresearch.net" , :authentication => :login, :user_name => "patelc75" , :password => "irdiktanic" ,   }

Here's the delivery code: class UserObserver < ActiveRecord::Observer   def after_create(user)     UserMailer.deliver_signup_notification(user)   end   def after_save(user)     UserMailer.deliver_activation(user) if user.recently_activated?   end end

Thanks! Chirag
