When I start Outlook 2000, I receive between 80 and 100 email messages that are "Delivery Status Notification (Failure)" messages.
None of these emails have never been sent from me
It seems that someone is faking the "from:" part of the email using my email address.
I don't think my account has been compromised, as none of the emails are leaving my mailbox, only being returned undelivered
How do I determine what is causing this and what do I do to resolve this problem?
