Mailer-Daemon

For about a week, the little envelope (Yahoo Mail) icon on my menu bar has been showing a red -1 - which would suggest that I have -1 emails in my inbox. This disappeared when I actually did have mail and the red number correctly told me how many mails were in my inbox.
Today at about noon, I started getting bombarded with emails from Mailer-Daemon @ Yahoo tellimg me about emails that have failed to deliver. It has been constant since it started and I've checked every one - over 200 so far andnone of these messages have I sent - and quite a lot are supposedly a failure to deliver a message from me to someone who isn't actually in my address book. Does anyone have any idea what's going on?

I had this for a couple of weeks, failed delivery to people I've never heard of, I changed my password and have not had any problem since.
