I've worked on a number of projects lately that have required the reviewing of HTML mail generated by ColdFusion's CFMail. In every development environment I've worked in the mail server is either 0.0.0.0 or there is a dummy mail gateway. In in either case knowing what the HTML will really look like can be difficult.

To help me with this issue I whipped up this very simple Adobe AIR app to help me look at the results. It's not a perfect solution and cannot account for the multitude of environments that the email will be viewed from, but it will render plain text and HTML emails close to what they would be viewed as in a mail client; it's also nice that to app is dead simple/basic.

Just point the app at your ColdFusion instance's "bad mail" folder and make sure your email server is set to 0.0.0.0 in CF Administrator
