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.
