spammer on server, can't find the script

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?

You can try this in the directory:
find ./ -name *.php Ś xargs grep -w "mail("

This will search for any PHP files containing the mail() function. 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.

Also found "How To Log Emails Sent With PHP's mail() Function To Detect Form Spam". Then you can read the logs. I have not tried this, but looks like a good idea.
