I have been receiving a Mailer Daemon@AOL.com for mail I never sent. They state that the mail is being returned to me because a address is undeliverable. I have never sent this mail and am receiving this message every day now.
Mailer-Daemon isn't a spammer, it's the name that comes back when the address you typed in was wrong or could not be found.
There's a possibility that someone has gotton your password for your AOL account and is useing your AOL email address to send various messages. Just to be on the safe side, I'd quickly change your AOL password. (PayPal, and eBay passwords too if you have them). Don't wait and it can't hurt if that is not the problem.
