removing www

[port15]

when I add a new account and use a subdomain,
ex: sub.domain.com instead of doing domain.com

how do I get rid of it using www.sub.domain.com?

Thanks.

I don't know too much but I thing you have to go in WHM to DNS/Edit dns zone, and select the new user's domain zone. there you can remove the www record. OR with ssh pico /var/named/sub.domain.com.db and remove the line starting with www
