OT: IP of computer sending message

[Thierry Chatelet]

Hi,
Is there a way to get the IP of the computer sending message, using Kopete?
I am receiving messages from someone who must have highjack my brother ID. I 
know that the messages dont come from his machine (I first thought it could be 
as he is running W$) because I phoned him and his computer is shut down.
Thanks
