[root /root]#

that is a directory listing from /root

and it has bits of an email randomly created from what looks like an email i
sent to the cobalt list, i thought it might have been a problem with
sendmail or something, but i checked the time of the email, and the time
that these files were created and they not related at all (apart from they
were both on the same day)

i have a feeling someone has seen me on the list, and has compromised my
machine

if anyone has anything to say in this, or have an explaination then please
reply to the list

 --Mike.
