By any chances, have you ran 'ps ax' from root and looked to see what does not look like it should be there??
The box is already down and replaced by a backup. Implemented some of your suggestions on it. Issue was unauthorized web site.I have bash_history logs for all the users created by hacker so I know commands run including starting httpd. When I get back from an 11 day business trip I will set those drives on a slow as molasses test machine and see what I can figure out...for educational purposes.

IF you are willing, paste your 'ps' output for us to help you find the program that is running and sending out the emails. also review your sendmail rule set. Next, to help lock down your server a little more make sure you have set a password on your VNC. I had and Italian 17 year old poking around one of my Amateur Radio boxes via VNC, simply cause I forgot to set a vnc password, so it was wide open like a windoz server box without a login screen, you know, the good old "I AM OPEN FOR YOUR PLEASURES..." Also change your sshd, the port it is on, and do a rule set that only allows a specific ip to access it. I think I am correct saying you can do that as well with VNC. The other option would be to stop the service all together IF your not needing it. Good Luck. Evans F.
