Here I made an email set-up using ActionMailer
Download this project and run following commands
- rake db:create
- rake db:migrate
- rails server
After run the server visit localhost:3000 and create an user. Email will generate and send to that user mail-id.
Dont forget to set your gmail id and password in environment/development.rb configuration file
I explained step by step how I made this email set-up in README.rdoc file.
