I've written a plugin for Qpsmtpd which does something like this in a perl application. It parses the email, and if it's a bounce takes an action based on the email address.

It may not work on shared hosting though, and for that you may want to create an email gateway which triggers a perl script. Take a look at Request Tracker's gateway interface as an example. Have your perl script filter the email for bounces, and take action if a bounce is identified, otherwise send the email on it's way.
