Q:
Can you stop spoofing?
Hacking, User access, Spoofing
I have a user that is getting spoofed. It is only happening to him. Sometime it happens to other users but it goes away after a couple of days. With this one user it has been 3 months. I thought it may have been a virus/spyware on his computer. I have ran every scan I have. I have exchange 2003 is there a way I can stop it at the exchange level.

What kind of spoofing are you talking about? If it is e-mail spoofing, that is really impossible to prevent since SMTP is not an authenticated protocol and the headers can easily be manipulated to forge the from address. Think about the return address on an envelope. Anything can be written on that area and yet the message will still get delivered to the recipient.

Another way of looking at this is how backscatter happens. This is discussed in this question/answer.
