Hello good afternoon.

Have a Zimbra server with four domains, three of which can send and receive external email, and a domain which does not send mail to external domains can send and receive most of the internal fields of business, now need to do that this domain intranet can only send email to some internal mail domains.

* Ex: user@teste4.dominio.com.br send and receive email over the user1@teste1.dominio.com.br can not send to user2@teste1.dominio.com.br, user3@teste1.dominio.com. en, etc ... teste1.dominio.com.br domain.
