Undeliverable messages I never sent

[Guest]

One of the fellas in the office recieved a Mail delivery failed, returning
message to sender. problem is he never sent it.
It contained an attachment that has been used by recent viruses or other
malware.
I'm not sure if this is because he might have picked up a worm or something
like that and wanted to know if anyone can help. The address that it was
trying to be sent to is not in his addresss book.

Two most likely possibilities:

1. This is a virus masquerading as an NDR
2. Someone, somewhere has this user's email address in their address book
and has a virus, and the virus is sending out messages spoofing the
sender....so the 'sender' gets the NDR for a message they didn't send.

Nothing you can do but make sure you have good antivirus installed, kept
updated, etc....delete the messages.

Yeah that is a virus still trying to work but has been stopped. Run a
thurough virus scan on it.

It's not a virus - someone is using your email address to send spam and the
spam that can't be delivered is being returned to you. Unfortunately
there's nothing you can do to prevent it...
