Internet_Mail_Server FQDN: mail.test.com
private IP: 10.0.0.225/24
Internet_Mail_Server MTA: POSTFIX, and facing the internet

Local_Mail_Server FQDN: local.test.com,
ip: 10.0.0.125/24
Local_Mail_Server MTA: POSTFIX, and Doesnt face the internet

Yet Didnt configure the Internet_Mail_Server(need help to configure)

following is the Postfix configuration of Local_Mail_Server :

myhostname = local.test.com
mydomain = test.com
myorigin = test.com
inet_interfaces = all
mydestination = $myhostname, localhost, $mydomain
mynetworks = 127.0.0.0/8, 10.0.0.0/24

rest of the options are all the default.

Now I need help to configure the

1, Local_Mail_Server to forward all the emails for outside/INTERNET to the Internet_Mail_Server(mail.test.com, private ip 10.0.0.225/24)

2, Internet_Mail_Server so that it will ACCEPT all the emails(going to internet) comming from Local_Mail_Server and then forward/pass those emails TO internet

3, Internet_Mail_Server so that it will forward/pass all the emails for test.com domain(comming from internet/outside) to the Local_Mail_Server(10.0.0.125/24)

Please help
