Hello All,

I have configured Zimbra in my local LAN as a internal mail server. called "jay.com". I have create 3 users like admin@jay.com, abc@jay.com, xyz@jay.com. Now I want to make policy as below.

1. User abc@jay.com and xyz@jay.com are allowed to send mail only on jay.com not anyother like gmail, yahoo.

2. admin@jay.com can send mail internal domain (jay.com) as well as external domain like yahoo, gmail etc....

At present I have allowed in relaying as below:
#cat /opt/zimbra/postfix/conf/main.cf |grep mynetworkmynetworks =
mynetworks =

Now how can restrict users as per above policy?
