Correct.  Of course, if we can track down a few of these bounces
immediately, we might not need to worry about it again for a while.
Or qmail might have something built into it that displays the original
recipient.  Note, I don't think this would be the case though.  Most
people usually view including the original recipient on the sending
side as a privacy issue, especially if someone was meant to be bcc'ed
on the mail.

That'd be good.  Although since mailman, as configured, sends the
message and a list of e-mail addresses to the MTA, I don't think that
it will be possible without changing the configuration, i.e., sending
each e-mail individually to the MTA.  Which means, of course, that
performance and bandwidth usage suffers.
