    A couple things..

    Turn on safe_mode in php.ini.

    Add the following to php.ini
    disable_functions = dl,system,exec,passthru,shell_exec

    ensure register_globals = Off

    You will need to test this to ensure your applications are still working properly.

    Also, you will need to determine if it is a php script that is being used to send spam. Do some research. You may find tools like 'lsof' useful.

    Also a creatve way to determine which script is sending mail, ay be to replace /usr/bin/sendmail with a script that captures command line options, such as calling script.

    You could also be an open relay. You can use dnsreport.com to check.
