Large number of undeliverables (2000)

Outlook is receiving several hundred returned e-mails each day. None of these are e-mails that have been sent. They just show up as returned. I have checked the machine for viruses with the latest virus definitions. Any suggestions as to how to go about stopping this?

There are several types of virus out there that spoof the sender’s address – i.e. someone with your email address in the address book gets hit and they send out emails supposedly from you.

may give you more info on the sender. Quite often the Subject line may give a hint as to the original validity of the mail.

Is there a specific reason for their return? No such user? Mailbox full? Several hundred a day still sounds a lot – perhaps you have an auto-responder bouncing back-and-forth…?
