If you are doing this as an exercise, then @solarnz has the right approach. If however, you need this done for work there is a far better solution in mailcatcher:

MailCatcher runs a super simple SMTP server which catches any message sent to it to display in a web interface. Run mailcatcher, set your favourite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check out http://127.0.0.1:1080 to see the mail that's arrived so far.

This is a program designed especially for developers whose apps need a mail server for testing but they don't want to set one up.

The great bonus is that it comes with a web interface to view messages sent by your application:
