    We don't especially mind that your English is weak, but in this case, it's getting in the way of your meaning. Can you explain your problem in a different way?

    What you have done is allow ALL email traffic on the network to be treated as LOCAL.
    Do you have a firewall between the 10.* network and the world?
    My guess would be that your zimbra server is seeing all addressed that come through the Firewall as 10.* network addresses "The Firewall's address".

    Put exact address for machines that you want to relay for in MyNetworks.

    as zimbra user
    zmprov modifyserver YourZimbraServer zimbraMtaMyNetworks ' 10.0.0.nn/32
    repeat the 10.0.0.nn/32 for each server you need to relay for.

    zmprov modifyserver YourZimbraServer zimbraMtaMyNetworks ' up to'
    if lookup from a file/table is possible, i have no idead its syntax
