cPanel & WHM version 11.40
Preventing the nobody system user from sending mail to remote addresses prevents would-be abusers from having any anonymity in process accounting. This is because PHP and CGI scripts generally run as nobody when the system is using mod_php, or when suEXEC is disabled.
You can access the Prevent “nobody” from sending mail setting at Home >> Server Configuration >> Tweak Settings, under the Mail Tab.
