Glen,
This is fairly normal. When spammers send out campaigns they pretty
much use spoofed addresses. Unfortunately your address as well as
others in your domain have been used thus you are receiving the back
scatter. On some of the servers I maintain for clients we have seen
waves of undeliverables at a rates in excess of 1000 messages per minute.
Depending on how bad the storm is I typically will put in place a from
filter that deletes the null sender for a period of time.
David (Declude) has posted some filters in the customer portal that
deals with this, but I have not tested them at this time.

I’m on imail 9 with declude. I have users sending coments like this:
We just got hit with something big- you might want to check things out.
I received 28 delivery failure notices- postmaster dameon..... in 2
minutes! Didn't open anything- just was looking to see if I had any new
mail. I notice the spam folder also contains them!
I had one user get 600 of these in two days. Any advice?
