sendmail

I've noticed one of my server is sending mass spam.

The messages are like the one below (sending from: [email protected]). I've deleted USER_ACCOUNT but I'd like to know how can I identify the script (probably a hacked PHP script) that sends the mass mail considering this server hosts numerous websites.
