celluloid-smtp-sample

Clone this repo and install the dependencies with bundler.

Then choose to run a celluloid or EM based server by running ./bin/celluloid or /bin/em.

You can use swaks to send mails into the server and see how it behaves, something like this:

$ swaks -s 127.0.0.1 -p 1025 -t joe@mailinator.com

Have fun :)
