Very cool. I'd love to know what technique they used to build the dialogs with the simulated chat, with the text animation sequences filling out the "DMARC Results" area -- what does the source for this UI look like?
Edit: Just found the `terminal.analyze` function: very cool. That `terminal.echo` is so clever.
That's what I thought was neat about this site. There are plenty of MX testers out there, but I felt this was pretty unique. I thought it was a great idea that it interrogates a send email rather than just look up DNS entries.
