[SOLVED] Bounced Emails

We've run into a case where the email address in the 'To:' filled was entered incorrectly and I'm trying to figure out where the bounced return email would have gone. It was not received at the 'From:' address. Any ideas where to start?

Hi redrings,

Could be anywhere, if it's really that important and you know the incorrect email address then talk to your ISP but don't expect to get too far.

Bob,

I actually just got off the phone with the server guys about 2 seconds ago and found out that they were blackholed.

Thanks for the reply!
