The bounces usually just cause annoyance and confusion, actually
(assuming you're talking about bouncing emails back to the"From:"
address). We get an immense number of confused emails from users who
have received bounced messages because their address was spoofed. So at
least *I* would prefer you didn't do it. To be helpful, if you have the
energy, checkout the Received: headers and contact the relevant ISPs--
though I don't know how much they'll appreciate it, either.
