Hi Experts,

I need your help for ZCS 7.1.4 configuration. I have few requirements

1. ZCS should allow only authenticated users of @mydomain.com, regardless of mynetworks configuration in postfix or MTA tab.
(Email sending and receiving should not be limited to NETWORKS. Users should be able to send receive emails from anywhere but authenticated Users only.)
2. No other domain should be allowed from my server (means it should not be open-relay server)
3. @mydomain Users should not be able to send (lets say) more than 100 emails /hour.
Please, Please, Please help, how can I do this Via ZimbraCS....
