Hi All,

I have a query regarding a possible hack on our new Sun Web mail system. Is 
anyone able to help with a query. We have just gone live for POP web mail 
and have noticed one of our test web mail accounts appears to have been 
compromised or hi-jacked, by multiple timeouts whereby another IP address 
was reported as using the session.

Is the below log report just reflective of a seemingly innocuous web bot of 
some type, or perhaps a hacker hiding behind Google range...???

We are running Sun Java Enterprise System 2.0 with UWC multiplexes deployed 
at the front of the firewall talking back to the email back end behind the 
Our main questions are:

Any other ideas, hints, suggestions or fixes etc etc would be very appreciated.
