What, you've never seen spamware/worms forge the From: and To: based on what
data they can find on a victim's machine?  Some poor guy on a DSL line near
Topeka Kansas got something evil on his machine, and it sent out mail (either
an exploit or spam) with a From: pointing to your listserv and a To: pointing
at the unsub'ed user.  Then when it bounces because the source is a DSL line,
the bounce goes back to Listserv (Yes, I *know* this requires multiple different
sub-optimal configuration choices by multiple sites. Happens all the time :)

Or even more evil, they managed to run the bounce counter up to 299 - and then
when your probe bounced, it went over the top.
