Zimbra MTA MyNetworks Not Working


The default zimbra postfix configuration allows relaying only for the local network, but we can configure postfix to allow relaying unconditionally for other / remote networks.

When you need ? … You are observing “Relay Access Denied” errors in the MTA log (/var/log/zimbra.log) for hosts or subnets that you trust for relaying.

Checking the your zimbra configuration
# su – zimbra
$ postconf mynetworks
mynetworks =

Allowing relaying for a remote machine

Let’s say you have a single machine on a remote network  with the IP address, and the current settings look like above, then
Add the remote machine like this:

zmprov ms zimbra.example.com zimbraMtaMyNetworks ‘’

postfix reload


You can not modify MTA Mynetworks via GUI.  Not working, although you perform restart zimbra ( zmcontrol stop & zmcontrol start ). You must to do via  CLI.

thanks you
