No. The symptoms aren't right. In this case what you get is what definitely appears to be a genuine delivery failure message (including quoting your original post). All the headers appear correct, and consistent with the address the message claims to come from. There's no additional payload. A virus masquerading as a delivery failure would: o Not quote a genuine message in the body. o Contain additional payload (the virus) o Have spoofed addresses that don't match the headers (and which would vary from message to message) o Be generated spontaneously, not only in response to a posting.
