Regarding my messages

Before someone else sends me a message telling me to fix this, our email 
addresses are publically visible in the archives and the list server strips 
the source addressing info so I can't see what server is sending with my 
username to this list.  My server is not sending/relaying these messages to 
the list.  I have full logging turned on and I am only seeing inbound 
messages for every one of these no outbound. 

If someone wants to show a message coming from my address that contains the 
virus I will be happy to trace it down and fix it.  But if i do have problem 
it would be an indication of a Linux box being infected with this virus as I 
don't have any windows boxes running at the moment.
