I - THE PROBLEM
I have a cpanel/whm server where some clients use php scripts to send mail. The clients scripts use sendmail link.
Some times the spammers use the clients scripts to send email to rcpt out of the server.
I need block clients php scripts to send email to rcpt out of the server.
I need the clients php scripts to continue sending email to client email accounts into the server.
