I have received a significant number of "undelivered mail" messages, all with mysterious techno-gibberish, and none of which bore any resemblance to any email I had sent out. Each had a single attachment. To me that seems suspicious.
After breaking into somebody's computer, a spammer sends emails to a list of random addresses (Rumpelstiltzkin attack) with a fake return address. The messages bounce, and the bounce message is undeliverable, causing it to be bounced to your postmaster alias. The attachment is probably a worm that constitutes the trespass of step 1 above.
