msg:3971534 | 9:48 pm on Aug 13, 2009 (gmt 0) | I have a cpanel server that apparently has a PHP script sending spam. There are quite a few accounts on the machine and I can't seem to find the script that is doing it. Any suggestions on how to track it down?

From there, you can get an idea of which scripts are sending emails out. If it's a script that allows visitors to send emails out (such as a 'email this' or 'share this'), a captcha may be needed so bots can't abuse it.
