limit mail to internal only

Post by 1netadmin »

How do I limit mail so that only messages for my domain are accepted? Basically, we are using Zimbra as an internal messaging system and don't want any mail to leave the company. So if my domain is xxyy.com, I don't want users to be able to send mail to yahoo.com (for example). They should only be able to send and receive mail from xxyy.com.

Thanks
