I also have been getting Delivery Status Notification(Failure)
about recipient's BlackBerry Handheld. But following that I also get
mail from the questions postmaster saying my emaill is spaming junk mail
and it has a zip file attached.
The email headers only have single hop to me. Looks like forged email.
Sender hoping i will unzip the file so it can install a Trojan. I just
delete it.
