    40 Undeliverable mail messages (2003 SP2)

    Hi,
    Last night I received about 40 'undeliverable mail' messages for messages I never sent. My immediate thought was some kind of trojan, but I have Zone Alarm Pro, AVG anti-virus, Spywareguard and when I ran AVG it turned up nothing.
    So have I been hacked? How could this happen when my computer is tighter than Fort Knox? And what can I do about it if it can't be detected?
    Thanks for any insight you might have.

    The most probable explanation is that someone else's computer is infected and is sending out e-mails with you as sender (this kind of malware often uses e-mail addresses in the infected user's address book/contacts folder as sender).

    You could open one of the messages and look at View | Options to see if you can find out where it really comes from. If it's from someone you know, you could warn him/her, but if it's from somewhere abroad, there's not much you can do about it, except hoping that it blows over soon.

    I'll second HansV's answer. I went through a period when I was getting so many of those that I added a filter to automatically junk them. I keep my AV and firewall up to date and scan for spyware regularly so I never concerned myself with them.
