Configure Zimbra for relay for another servers

Note Configure -> MTA -> "MTA Trusted Networks:" will not work. This particular change *MUST* be done from command-line only.


To allow another servers emails via Zimbra (ie configure Zimbra server as relay for another server) use:

  1. (As zimbra user) Check current whitelist setting for server
    zmprov gs zimbra.example.com zimbraMtaMyNetworks
  2. Then append desired additional network to above output and set new MyNetworks using:
    zmprov ms zimbra.example.com zimbraMtaMyNetworks '127.0.0.0/8 10.10.130.0/24 10.10.200.25/32'
  3. Reload postfix for new settings to take effect:
    postfix reload
