How to remove only e-mail service from the domain

[kemperalves]

Hi all,

I'm from brazil, I instaled de ispcp and its work fine to me! Excelent work.

But, I have a question:

In my domain: http://www.mignet.com.br, alright add to ispcp, but, this domain use the google apps with g-mail as mail agent. I edit de /var/cache/bind/mignet.com.br.db and its ok for the domains outside this server. But, in the server I have other domains, and when its other domains try to send a mail to xxx@mignet.com.br, its fail, because the user xxx dont have a account on mignet.com.br. But, xxx have a account in the mail server (google), how I remove the domain mignet.com.br from the postfix in this ispcp?

I need to remove only mignet.com.br from the postfix of my ispcp.

thanks
