here contents of config/initializers/setup_mail.rb

am using heroku , sendgrid , have installed plug-in.

did need install 'mail' gem first, documentation doesn't mention it??

actionmailer::base.smtp_settings = { :address        => "smtp.sendgrid.net", :port           => "25", :authentication => :plain :user_name      => "apxxxxx@heroku.com", :password       => "9xxxxxxxxx", :domain         => "www.myapp.com", }

i know issue - there no comma after user-name , password entries!
