Turning bounced emails into a revenue channel

"When you route your bounced email to, we run each one through a complex, patent-pending system to split the traffic into two groups: machine mail and human generated mail. Enhanced bounces are only sent to actual human senders, and the machine mail is captured as either a private data feed back to your network operations team or added to our global anti-spam trap feed"
Have you guys thought about using this for human or company level intelligence (eg when people leave jobs)?
@borker We have, but I'd be curious to know more of your thoughts. Shoot me an email:
