Testing changes in outgoing emails

1. Start mailcatcher:

    $ mailcatcher
    Starting MailCatcher
    ==> smtp://127.0.0.1:1025
    ==> http://127.0.0.1:1080
    *** MailCatcher runs as a daemon by default. Go to the web interface to quit.
   

2. Open a Rails console:

    $ script/rails console
   

3. Send an email via RequestMailer:

    > r = InfoRequest.last
    > RequestMailer.overdue_alert(r, r.user).deliver
   

That's it, your outgoing email should show up in MailCatcher. And you don't need to restart the Rails console for edits to the template to take effect. Yay.
