Security SMTP Bug still in CPanel Server?

just going to check SMTP on a CPanel server and saw anyone is still able to send e-mail's trought servers SMTP : mail.anyaccount.com
I have already set the security tweak in WHM:
"SMTP Mail protection has been enabled. Only users with the gid mail or mailman may make smtp connections. "

but it is not working. I tried anso to change my IP address (so without login in ) but I am still able to sending e-mails.
Have also customers that claims somon using there smtp.theredomain.com to sending spam.

Anything that can be done?

thanks a lot
