Zimbra: changing postfix parameters

postfix zimbra

I found the solution to my own problem. By looking at the file /opt/zimbra/conf/zmmta.cf, I saw the following lines:

if VAR zimbraMtaMyNetworks
    POSTCONF mynetworks VAR zimbraMtaMyNetworks
fi

With zmprov I can check the current settings and change them:

zmprov getServer servername.mydomain | grep zimbraMtaMyNetworks
zmprov modifyServer servername.mydomain zimbraMtaMyNetworks "127.0.0.0/8 [...]"
postfix reload

And the problem is solved. Xeon suggested an alternative and simpler way:

You can also change this in the Admin Console under Server Settings -> MTA -> MTA Trusted Networks

No, wait, actually it's much better, because of the wide skillset and quantity of geeks.

I would like to change mynetworks Postfix configuration parameter in Zimbra 7 on Debian GNU/Linux 5.0.

I tried the following (as zimbra user):
```
$ zmlocalconfig -e postfix_mynetworks="127.0.0.0/8 [...]"
$ postconf -e mynetworks="127.0.0.0/8 [...]"
$ zmmtactl reload
$ postfix check
$ postfix reload
```
However
```
$ postconf mynetworks
```
Shows still the old value! Anyone knows why and how to fix this? Thank you in advance

UPDATE After office hours I've even tried
```
# /etc/init.d/zimbra stop
# /etc/init.d/zimbra start
```
However the parameter is still not updated.

UPDATE 2
```
$ zmlocalconfig postfix_mynetworks
```
Shows the updated value
```
$ zmmtactl reload
Rewriting configuration files...
postfix/postfix-script: refreshing the Postfix mail system
Stopping saslauthd...done.
Starting saslauthd...done.
```
But sadly postconf mynetworks still shows the old value. Running again postconf -e sets the value and gets lost at the first postfix reload...
