I have heard from a couple external users that are pretty irate that our
bounces are going to them when their address was spoofed.  They say that
the RFC is wrong and we should just reconfigure our environment according
to their specifications.  In fact, that is SpamCop's contention also.  We
haven't done that yet.

We see this occasionally, but not often.  And no uptick here in recent

It does cause a serious issue if the chosen address
used by the spammer, also happens to be a real
address in use here at Northwestern.  We have
heard of people receiving hundreds of bounced messages
per day if this happens.  We recommend filters,
but there's little else we can do to stop this.

My questions are two.  Is this happening elsewhere,
and if so, have you recently noticed an increase
in this activity?
